Marbach et al. (2020 - medRxiv : https://doi.org/10.1101/2020.09.10.20190314 - last author : C. Schaaf) report 6 unrelated individuals with heterozygous missense PRKAR1B variants. All presented formal ASD diagnosis (6/6), global developmental delay (6/6) and intellectual disability (all - formal evaluations were lacking though). Additional features included neurologic anomalies (movement disorders : dyspraxia, apraxia, clumsiness in all, with tremor/dystonia or involuntary movements as single occurrences). Three displayed high pain tolerance. Regression in speech was a feature in two. Additional behavior anomalies included ADHD (4-5/6) or aggression (3/6). There was no consistent pattern of malformations, physical anomalies or facial features (with the exception of uplsanted palpebral fissures reported in 4). 3 different missense variants were identified (NM_00116470:c.1003C>T - p.Arg335Trp, c.586G>A - p.Glu196Lys, c.500_501delAAinsTT - p.Gln167Leu) with Arg355Trp being a recurrent one within this cohort (4/6 subjects). A possible splicing effect may apply for the MNV. All variants are absent from gnomAD and the SNVs had CADD scores > 24. In all cases were parental samples were available (5/6), the variant had occurred as a de novo event. Protein kinase A (PKA) is a tetrameric holoenzyme formed by the association of 2 catalytic (C) subunits with a regulatory (R) subunit dimer. Activation of PKA is achieved through binding of 2 cAMP molecules to each R-subunit, and unleashing(/dissociation) of C-subunits to engage substrates. PRKACA/B genes encode the Cα- and Cβ-subunits while the 4 functionally non-redundant regulatory subunits are encoded by PRKAR1A/1B/2A/2B genes. As the authors comment, the RIβ subunit is primarily expressed in brain with higher expression in cortex and hypothalamus. The functional consequences of the variants at cellular level were not studied. Previous studies have demonstrated that downregulation of RIβ in murine hippocampal cultures, reduced phosphorylation of CREB, a transcription factor involved in long-term memory formation. The authors speculate that a similar effect on cAMP/PKA/CREB cascade may mediate the cognitive effects in humans. RIβ deficient mice also display diminished nociceptive pain, similar to the human phenotype. [Several refs provided]. The authors cite the study by Kaplanis et al (2020 - PMID: 33057194), where in a large sample of 31,058 trio exomes of children with developmental disorders, PRKAR1B was among the genes with significant enrichment for de novo missense variants. [The gene has a pLI score of 0.18 in gnomAD / o/e = 0.26 - so pLoF variants may not be deleterious]. Please note that a specific PRKAR1B variant (NM_002735.2:c.149T>G - p.Leu50Arg) has been previous reported to segregate with a late-onset neurodegenerative disorder characterized by dementia and/or parkinsonism within a large pedigree with 12 affected individuals [Wong et al 2014 - PMID: 25414040].

The authors performed microarray and exome sequencing in 192 consanguineous families and identified a homozygous ITGF2 stopgain variant (NM_018463.3:c.472G>T / p.Glu158*) along with 3 additional variants segregating with ID within an investigated family (PK51). Cheema et al (2020 - https://doi.org/10.1038/s41525-020-00150-z) report briefly on a male, born to consanguineous parents presenting with NDD, seizures, regression and ataxia. There was a similarly affected female sibling. Evaluation of ROH revealed a homozygous ITFG2 nonsense variant [NM_018463.3:c.361C>T / p.(Gln121*)]. Families in this study were investigated by trio WES or WGS. Evaluation of data of the same lab revealed 3 additional unrelated subjects with overlapping phenotypes, notably NDD and ataxia. These individuals were - each - homozygous for pLoF variants [NM_018463.3:c.848-1G>A; NM_018463.3:c.704dupC, p.(Ala236fs), NM_018463.3:c.1000_1001delAT, p.(Ile334fs)]. As discussed in OMIM, ITFG2 encodes a subunit of the KICSTOR protein complex, having a role in regulating nutrient sensing by MTOR complex-1 (Wolfson et al 2017 - PMID : 28199306). Rated Amber as Cheema et al report on diagnostic outcomes and multiple candidate genes as part of a heterogenous cohort and details are therefore limited. Sources: Literature |

Zornitza Stark commented on gene: HPDL: 17 individuals from 13 families, with a spectrum of neurologic impairment ranging from a severe congenital form without any neurological development (n = 2/17, 12%) to infantile-onset presentations (n = 10/17, 59%) with moderate to severe neurodevelopmental issues, partly with a pathology reminiscent of mitochondrial disease (Leigh-like syndrome), to juvenile-onset spastic paraplegia (n = 5/17, 29%). Frequently observed clinical findings included chronic progression of neurological signs (n = 16/17, 94%), motor developmental delay (n = 12/17, 71%), intellectual impairment (n = 11/17, 65%), microcephaly (n = 9/16, 56%), and seizures/epilepsy (n = 9/17, 53%). Other relevant clinical findings were visual disturbances/strabismus (n = 9/17, 53%) and loss of developmental milestones (n = 6/17, 35%). Acute central respiratory failure leading to life-threatening events requiring partly mechanically assisted ventilation occurred in half of individuals with infantile presentation (n = 5/10, 50%), respectively one third of all individuals (n = 5/17, 29%). Demyelinating neuropathy was present in three individuals (n = 3/11, 27%), with reduced sensory nerve conduction velocity (NCV) in all and severely reduced motor NCV in one. |

Parental segregation confirmatory in patient 1, quantitative PCR analysis confirmatory in patient 2). Functional tests performed on platelets of one patient displayed an absence of the obligate multisubunit complex BLOC-1, showing that the variant disrupts BLOC1S5 function and impairs BLOC-1 assembly. Expression of the patient-derived BLOC1S5 deletion in nonpigmented murine Bloc1s5-/- melan-mu melanocytes failed to rescue pigmentation, the assembly of a functional BLOC-1 complex, and melanosome cargo trafficking, unlike the wild-type allele.

| Mendeliome v0.4520 | SLC12A2 |
Zornitza Stark edited their review of gene: SLC12A2: Added comment: Monoallelic : DD/ID was a feature in >= 6 individuals with monoallelic de novo SLC12A2. An individual with an exon 22 truncating variant was reported to have normal milestones and cognitive function. Exon 21 variants have been described in individuals with rather isolated hearing impairment (possibly some associated motor delay, but normal cognition). Hearing impairment was also reported in 2/6 patients with variants in other exons (1 missense / 1 frameshift). Biallelic : DD/ID was reported in at least 3 individuals in literature. Hearing impairment has been reported on 2 occasions (although this was not probably evaluated in all subjects). --- Monoallelic SLC12A2 mutations : ► Individuals with de novo mutations and developmental disorder were first identified by the DDD study (2017 - PMID: 28135719). 5 of them have been reported in detail by McNeill et al (below). ► McNeill et al (2020 - PMID: 32658972) report on 6 individuals with neurodevelopmental disorder due to de novo SLC12A2 mutation. All presented DD or ID ranging from mild to severe. ASD was reported in 3/6. Sensorineural hearing loss was a feature in 2/6 with the remaining having normal formal evaluations. Brain, cardiac and/or additional malformations were reported in a single individual. Following non-diagnostic prior work-up (CMA, FMR1 or other investigations) trio exome sequencing revealed missense (4/6) or truncating variants (2/6). Three additional individuals (incl. a father and his son) with missense variants in exon 21 (NM_001046.3 / p.Glu979Lys and p.Glu980Lys) presented with bilateral sensorineural hearing loss. Speech and/or motor delay reported in these cases were attributed to the hearing impairment/vestibular arreflexia (cognitive abilities not tested). SLC12A2 encodes sodium-potassium-chloride transporter 1 (also NKCC1). The GTEx project has identified 8 isoforms. In brain both exon 21-containing/deleted isoforms are expressed (cited Morita et al 2014 - PMID: 24695712). As the authors discuss, RNA-seq of the developing mouse cochlea suggests that the exon 21 containing isoform is the single transcript expressed. Evidence from RNA-seq data (BrainSpan project) and literature suggests that the significant amounts of exon 21 lacking isoforms in fetal brain compensate for the deleterious effects of exon 21 variants and explain the lack of NDD in relevant patients. Slc12a2 (NKCC1) null mouse model has demonstrated that the transporter plays a role in accumulation of the potassium rich endolymph in the inner ear, with NKCC1 absence causing sensorineural deafness and imbalance. Slc12a2 display cochlear malformations, loss of hair cells and hearing impairment (cited Delpire et al 1999 - PMID: 10369265). The brain phenotype has not been studied extensively, although loss of Slc12a2 has been shown to inhibit neurogenesis (cited: Magalhães and Rivera et al. - PMID: 27582690). Slc12a2 null zebrafish display a collapse of the otic vesicle and reduced endolymph (Abbas and Whitfield, 2009 - PMID: 19633174) relevant to the human hearing disorder. In vitro assessment of NKCC1 ion transporter function in Xenopus laevis, supported the deleterious effect of the identified variants (significant reduction in K+ influx). Using available single cell RNA-seq data the authors further demonstrated that SLC12A2 expressing cells display transcriptomic profiles reflective of active neurogenesis. ► Delpire et al (2016 - PMID: 27900370 - not reviewed in detail) described a 13 y.o. girl harboring a de novo 11-bp deletion in SLC12A2 exon 22. This individual reached developmental milestones on time and had a NORMAL cognitive function. Hearing was seemingly normal. Features included orthostatic intolerance, respiratory weakness, multiple endocrine abnormalities, pancreatic insufficiency and multiorgan failure incl. gut and bladder. Exome in the proband, parents and 3 unaffected sibs suggested SLC12A2 as the only candidate for her phenotype. Functional analyses in Xenopus laevis oocytes suggested that a non functional transporter was expressed and trafficked to the membrane as the wt. Detection of the truncated protein at higher molecular sizes suggested either enhanced dimerization or misfolded aggregate. There was no dominant-negative effect of mutant NKCC1. In patient fibroblasts a reduced total and NKCC1-mediated K+ influx. ► Mutai et al (2020 - PMID: 32294086) report on several individuals from 4 families, harboring variants within exon 21 or - in one case - at it's 3' splice-site (leading to skipping oe this exon at the mRNA level). All subjects were investigated for severe/profound hearing loss (in line with the role of exon 21-included isoforms in cochlea. The variant segregated with hearing impairment in 3 generations of a family while in all other subjects the variant had occured as de novo event. Despite motor delays (e.g. the subject from fam2 could not hold head or sit at the age of 10m / the proband in Fam3 was able to hold his head and walk at 6 and 20 m respectively) behavior and cognition were commented to be within normal range. ----- Biallelic SLC12A2 mutations: ► Anazi et al (2017 - PMID: 29288388) briefly reported on a 3 y.o. boy (17DG0776) with central hypotonia, neonatal respiratory distress, failure to thrive, global DD and microcephaly and a skeletal survey suggestive of osteopenia. After non-diagnostic prior investigations (CMA revealing a 1p duplication classified as VUS, extensive metabolic workup), WES revealed a homozygous SLC12A2 splicing variant [NM_001046.2:c.2617-2A>G]. ► Macnamara et al (2019 - PMID: 30740830) described a 5.5 y.o. male with sensorineural hearing loss, profound delays in all developmental areas among several other features (choanal atresia, failure to thrive, respiratory problems, absent sweat and tear production or salivation, GI abnormalities). Genetic testing for several disorders considered (cystic fibrosis, spinal muscular atrophy, sequencing and del/dup analysis of mtDNA) was normal. CMA revealed paternal uniparental isodisomy for chr. 5 and WGS a homozygous 22kb deletion in SLC12A2. This was followed by confirmation of homozygosity in the proband, heterozygosity of the unaffected father, delineation of breakpoints (chr5:127441491-127471419). mRNA studies in patient fibroblasts confirmed deletion of ex2-7, splicing of ex1 directly to ex8 and introduction of a premature stop codon in ex9. qRT-PCR confirmed that mRNA is likely subjected to NMD (expression ~80% of control). Western blot confirmed absence of the protein in the patient's fibroblasts. Again mouse models are thought to recapitulate the hearing defect but also the deficient saliva production (cited Evans et al 2000 - PMID: 10831596). Again the authors speculate a role of SLC12A2 in brain development based on evidence from murine models (migration, dendritic growth, increse in neuron density through regulation of GABAergic signalling (Young et al 2012 - PMID: 23015452). Hypotheses are also made on a regulatory relationship between NKCC1 and CFTR based on mRNA data from the ko mouse model. ► Stödberg et al (2020 - PMID: 32754646) reported 2 sibs with a complex neurodevelopmental disorder due to compound heterozygosity for a frameshift SLC12A2 variant and a splicing one (NM_001046:c.1431delT and c.2006-1G>A). Both presented hypotonia, neonatal S. aureus parotitis and respiratory problems (incl. apneas). While the older sib died at the age of 22 days, the younger one had persistent respiratory issues incl. a dry respiratory mucosa motivating metabolic, immunology investigations and testing for CF. She displayed microcephaly (OFC -2.5 SD, H was also -3.5SD), severe intellectual disability. MRI was suggestive of white matter and basal ganglia abnormalities. Other features incl. hearing impairment, and lack of tears,saliva and sweat, constipation and intestinal malrotation. There was facial dysmorphism. The variants were the only retained following WGS of the 2 affected sisters, parents and an unaffected brother. The splicing variant was shown to result in skipping of exon 13, while the indel in NMD. Again the authors discuss that the deficient saliva production, impaired hearing and GI problems are recapitulated in the mouse model (several refs provided).; Changed rating: GREEN; Changed publications: 28135719, 32658972, 27900370, 32294086, 29288388, 30740830, 32754646; Changed phenotypes: Kilquist syndrome, deafness, intellectual disability, dysmorphic features, absent salivation, ectodermal dysplasia, constipation, intestinal malrotation, multiple congenital anomalies; Changed mode of inheritance: BOTH monoallelic and biallelic, autosomal or pseudoautosomal |

Neurological manifestations were reported in 16 individuals from 14 families (data not available for 1 fam), among others hypotonia (3/14 fam), speech delay (4/14 fam), global DD (9/14 fam), ID (4/14 fam), microcephaly (4/14 fam). ASD was reported in 4 fam (4 indiv). Seizures were reported in 2 fam (2 indiv). Variable other features included cardiac defects, facial dysmorphisms, small hands and feet with dys-/hypo-plastic nails and clinodactyly. 14 pLoF variants were identified, in most cases as de novo events (8 fam). In 2 families the variant was inherited from an affected parent. Germline mosaicism occurred in 1 family. The human disease features were recapitulated in a X. tropicalis morpholino knockdown, with expression of truncating variants failing to rescue renal and craniofacial defects. Heterozygous Zmym2-deficient mice also recapitulated the features of CAKUT. ZMYM2 (previously ZNF198) encodes a nuclear zinc finger protein localizing to the nucleus (and PML nuclear body). It has previously been identified as transcriptional corepressor interacting with nuclear receptors and the LSD1-CoREST-HDAC1 complex. It has also been shown to interact with FOXP transcription factors. The authors provide evidence for loss of interaction of the truncated ZMYM2 with FOXP1 (mutations in the latter having recently been reported in syndromic CAKUT). Sources: Literature |

Features included DD (9/10), ID (6/8 of relevant age), microcephaly (7/10), seizures (5/10 - >=3 different variants), structural brain abnormalities (e.g. thin CC in 6/9), highly variable ocular abnormalities (5/10) and dysmorphic features in some (7/10 - nonspecific). All had variable prior non-diagnostic genetic tests (CMA, gene panel, mendeliome, karyotype). WES/WGS revealed LMBRD2 missense variants, in all cases de novo. A single individual had additional variants with weaker evidence of pathogenicity. 5 unique missense SNVs and 2 recurrent ones (NM_001007527:c.367T>C - p.Trp123Arg / c.1448G>A - p.Arg483His) were identified. These occurred in different exons. Variants were not present in gnomAD and all had several in silico predictions in favor of a deleterious effect. There was phenotypic variability among individuals with the same variant (e.g. seizures in 1/3 and microchephaly in 2/3 of those harboring R483H). The gene has a pLI of 0 (although o/e ranges from 0.23 to 0.55), %HI of 15.13 and z-score of 2.27. The authors presume that haploinsufficiency may not apply, and consider a gain-of-function/dominant-negative effect more likely. As the authors comment LMBRD2 (LMBR1 domain containing 2) encodes a membrane bound protein with poorly described function. It is widely expressed across tissues with notable expression in human brain (also in Drosophila, or Xenopus laevis). It displays high interspecies conservation. It has been suggested (Paek et al - PMID: 28388415) that LMBRD2 is a potential regulator of β2 adrenoreceptor signalling through involvement in GPCR signalling. ► Kaplanis et al (2020 - https://doi.org/10.1101/797787) in a dataset of 31058 parent-offspring trios (WES) previously identified 3 individuals with developmental disorder, harboring c.1448G>A - p.Arg483His.

Both presented with an early onset neurological phenotype with severe global DD, ID (2/2 - moderate and profound), spasticity (2/2), ophthalmic findings (strabismus 2/2, nystagmus 1/2). Epilepsy, abnormal brain MRI (cerebral and cerebellar atrophy and white matter hyperintensities) as well and additional findings were reported in one (always the same individual). Following a normal CMA, exome in the first case revealed a homozygous missense SNV (NM_005679.3:c.1165C>T / p.Arg389Cys) supported by in silico predictions. mRNA and protein levels were substantially reduced in fibroblasts from this subject. Only the patient and parents were tested for the variant but not 3 unaffected sibs (fig1). The second individual was homozygous for another missense variant (p.Arg405Cys) also supported by in silico predictions. The girl was the single affected person within the family with an unaffected sib and parents heterozygous for the variant. Several other unaffected relatives in the extended pedigree were either carriers for this variant or homozygous for the wt allele. TAF1C encodes the TATA-box binding protein associated factor (TAF) RNA polymerase I subunit. RNA polymerase I (Pol I) transcribes genes to produce rRNA. For Pol I to initiate transcription, two transcription factors are required : UBF (upstream binding factor encoded by UBTF) and SL1 (selectivity factor 1). The latter is formed by TBP (TATA-binding protein) and 3 Pol I-specific TBP-associated factors (TAFs). A recurrent de novo missense variant in UBTF (encoding the other Pol I transcription factor) causes a disorder with highly similar features. The specific variant acts through a gain-of-function mechanism (and not by LoF which appears to apply for TAF1C based on expression data). The authors hypothesize that altered Pol I activity and resulting ribosomal stress could cause the microcephaly and leukodystrophy (both reported in 1 - the same - individual). Sources: Expert list |

Zornitza Stark edited their review of gene: PIGQ: Added comment: Homozygous or compound heterozygous mutations in PIGQ cause Epileptic encephalopathy, early infantile, 77 (MIM #618548). Johnstone et al (2020 - PMID: 32588908) describe the phenotype of 7 children (from 6 families) with biallelic PIGQ pathogenic variants. The authors also review the phenotype of 3 subjects previously reported in the literature (by Martin et al, Alazami et al, Starr et al - respective PMIDs: 24463883, 25558065, 31148362). Affected individuals displayed severe to profound global DD/ID and seizures with onset in the first year of life. There were variable other features incl. - among others - genitourinary, cardiac, skeletal, ophthalmological anomalies, gastrointestinal issues. Within the cohort there was significant morbidity/mortality. PIGQ encodes phosphatidylinositol glycan anchor biosynthesis class Q protein, playing a role (early) in the biosynthesis of the GPI-anchor. Several genes in the GPI biosynthesis pathway cause multi-system disease with DD/ID and seizures. Flow cytometry has been used in individuals with PIGQ-related disorder. Serum ALP was elevated in some (4) although - as the authors comment - elevations are more typical in disorders affecting later steps of GPI biosynthesis. More than 10 variants have been reported to date (missense / pLoF).; Changed phenotypes: Epileptic encephalopathy, early infantile, 77, MIM# 618548 |

The phenotype corresponded to a neurodevelopmental disorder and - as the authors comment - consistently included DD, ID , behavioral problems. Postnatal growth delay was observed in approximately half. Hypertelorism, ptosis, downslant of palpebral fissures, wide nasal bridge as low-set/posteriorly rotated ears were among the facial features observed (each in 3 or more subjects within this cohort). Together with short/webbed neck and abnormalities of skin (lentigines / CAL spots) and growth delay these led to clinical suspicion of Noonan s. or disorder of the same pathway in some. Congenital heart defects (ASD, mitral valve insufficiency, though not cardiomyopathy) occurred in 4/7. Bleeding diathesis and lymphedema were reported only once. MAPK1 encodes the mitogen-activated protein kinase 1 (also known as ERK2) a serine/threonine kinase of the RAS-RAF-MEK-(MAPK/)ERK pathway. MAPK1 de novo variants were identified in all individuals following trio exome sequencing (and extensive previous genetic investigations which were non-diagnostic). The distribution of variants, as well as in silico/vitro/vivo studies suggest a GoF effect (boosted signal through the MAPK cascade. MAPK signaling also upregulated in Noonan syndrome).

Features included cognitive impairment (mild ID in one case, regression at the age of 12y in another, hypotonia and delayed milestones in a third aged 8m), seizures (3/3 - variable age of onset) and/or gingival overgrowth (2/3 - prior to initiation of AEDs). Other findings included behavioral abnormalities, mandibular anomalies, abnormal brain imaging and ophthalmologic or (rarely) audiometric evaluations. All were born to non-consanguineous couples and additional investigations were performed in some. Variants were identified by WES or trio WGS, with Sanger confirmation/compatible segregation analyses. In line with the pLoF variants, mRNA studies in fibroblasts from 2 unrelated affected individuals demonstrated significantly reduced (~80-90%) TBC1C2D mRNA levels compared to controls, restored following cycloheximide treatment. Protein was absent in patient fibroblasts. TBC-domain containing GTPase activating proteins are known as key regulators of RAB GTPase activity. TBC1D2B was shown to colocalize with RAB5-positive endocytic vesicles. CRISPR/Cas9-mediated ko of TBC1D2B in HeLa cells suggested a role in EGF receptor endocytosis and decreased cell viability of TBC1D2B-deficient HeLa cells upon serum deprivation. Genes encoding other TBC domain-containg GTPase-activating proteins, e.g. TBC1D7 and TBC1D20, TBC1D24 are associated with recessive neurodevelopmental disorders (with ID and/or seizures) and the pathophysiological defect in TBC1D2B-related disorder (deficit in vesicle trafficking and/or cell survival) is proposed to be similar to that of TBC1D24.

Clinical presentation included DD, ID (severe in 2 subjects from fam1, borderline intellectual functioning in fam2), dysmorphic features and brain abnormalities. Cerebellar anomalies were common to all with a molar tooth sign observed in one (1/3). Other findings limited to subjects from one family included acquired microcephaly, congenital contractures, spastic quadriplegia (each observed 2/3). Previous investigations were in all cases non-diagnostic. WES identified biallelic EXOC2 mutations in all affected individuals. EXOC2 encodes an exocyst subunit. The latter is an octameric complex, component of the membrane transport machinery, required for tethering and fusion of vesicles at the plasma membrane. As discussed ,vesicle transport is important for the development of brain and the function of neurons and glia. Exocyst function is also important for delivery of Arl13b to the primary cilium (biallelic ARL13B mutations cause Joubert syndrome 8) and ciliogenesis. Affected subjects from a broader consanguineous family (fam1) were homozygous for a truncating variant. Fibroblast studies revealed mRNA levels compatible with NMD (further restored in presence of CHX) as well as reduced protein levels. The female belonging to the second non-consanguineous family was found to harbor 2 missense variants in trans configuration. An exocytosis defect was demonstrated in fibroblasts from individuals belonging to both families. Ciliogenesis appeared to be normal, however Arl13b localization/recruitment to the cilia was reduced compared with control cells with the defect rescued upon exogenous expression of wt EXOC2. Mutations in other genes encoding components of the exocyst complex have been previously reported in individuals with relevant phenotypes (e.g. EXOC8 in a boy with features of Joubert s. or EXOC4 in nephrotic syndrome). The authors discuss on the essential role of EXOC2 based on model organism studies (e.g. impaired neuronal membrane traffic, failure of neuronal polarization and neuromuscular junction expansion seen in Drosophila Sec5 (EXOC2) null mutants).

In a screen of 104 probands with KS or nIHH, four heterozygous AXL mutations were identified in two KS and two nIHH unrelated subjects (two males and two females). Three of the variants appear to be too common in gnomAD v2.1 given the reported prevalence of KS reported in GeneReviews (1:30,000 in males and 1:125,000 in females): c.587-6C>T (normal splicing in RNA studies, NFE AF 0.0001472), p.Q361P (NFE 0.002560), p.L50F (AJ 0.004405).

Presenting features: hypotonia, failure to thrive, microcephaly (5/6), severe global DD and ID as well as features suggestive of a motor disorder (dystonia/spasticity/dyskinesia). Seizures were reported in 2 unrelated individuals (2/6). MRI abnormalities were observed in some with thin CC being a feature in 3. Affected individuals were found to be homozygous for truncating variants (4/5 families being consanguineous). The following 3 variants were identified (NM_001039672.2) : c.186dupT or p.Ala64fs / c.360_361insACAT or p.Gly121fs / c.598G>T or p.Glu200*. Yif1B KO mice demonstrate a disorganized Golgi architecture in pyramidal hippocampal neurons (Alterio et al 2015 - PMID: 26077767). Functional/network analysis of genes co-regulated with YIF1B based on available RNAseq data, suggest enrichement in in genes important for nervous system development and function.

| Mendeliome v0.2759 | TNRC6B | Zornitza Stark edited their review of gene: TNRC6B: Added comment: 17 unrelated individuals with heterozygous TNRC6B variants reported. Features included hypotonia (10/17), DD/ID (17/17 - ID was not universal: average IQ of 12 individuals was 73 (range : 50-113) with 4 having below 70), ADHD (11/17), ASD or autistic traits (8/17 and 5/17). Some/few presented with abnormal OFC (micro- / macrocephaly in 3/17 and 2/17), abnormal vision or hearing, variable other congenital anomalies, echocardiographic, GI or renal abnormalities, etc. Epilepsy was reported in 1/17. There was no recognisable gestalt.Detected variants included 14 pLoF, 1 missense SNV and 2 intragenic deletions. Variants had occurred as de novo events in 10/13 subjects for whom testing of both parents was possible. 3/13 subjects had inherited the variant from a parent with milder phenotype. Based on the type of variants identified, the pLI score of 1 in gnomAD and the HI index of 5.61%, the authors suggest haploinsufficiency as the most likely mechanism. Individuals with de novo TNRC6B variants have also been reported in larger cohorts (e.g. DDD study - PMID: 28135719, Iossifov et al - PMID: 25363768, Lelieveld et al - PMID: 27479843, Jónsson et al - PMID: 28959963).

Animal knockout functional studies supported gene-disease association. PMID: 30573563 "By analysing WES data based on allele frequencies of in-house controls, population allele frequencies and in silico prediction tools, two rare homozygous mutations in USP45 were identified in two unrelated families. Immunohistochemistry of USP45 in the human and zebrafish retinal sections revealed enriched expression in the inner segments of photoreceptors. The knockdown of usp45 transcript in zebrafish led to abnormal retinal development with effects on photoreceptors, which could be successfully rescued by wild-type usp45 mRNA. Moreover, targeted knockout of Usp45 in mice caused abnormal electroretinography responses, similar to that seen in patients with LCA." Sources: Literature |

This condition can be dominant (but rarely), where patients with these missense are diazoxide-responsive. Patients with recessively inherited variants are diazoxide-unresponsive (OMIM, PMID:11395395, PMID: 23275527, PMID: 23345197). Genotype-phenotype correlation: Permanent neonatal diabetes – GOF (OMIM) Permanent neonatal diabetes + other features – GOF (OMIM) Congenital hyperinsulinism – LOF (PMID:18250167). PTCs - LOF Missense - Loss and gain of function LOF – cause reduce channel expression, channel activity and increase current decay (PMID:18250167) GOF - impair ATP-based sensitivity, more open state channel (OMIM) Mutations generally occur on the paternal allele (PMID: 23345197).; Changed publications: PMID:18250167, 11395395, 23275527, 23345197 |

Patient cell extracts showed absence of the full-length TDP2 protein and absence of 5-prime TDP activity, consistent with a loss of function, although 3-prime TDP activity, conferred by TDP1, was normal. In addition, patient lymphoblastoid cells were hypersensitive to the TOP2 poison etoposide. The findings indicated impaired capacity for double-strand break repair. 1 unrelated Egyptian patient with a similar disorder was homozygous for a truncating mutation in the TDP2 gene 1 unrelated Caucasian patient with same homozygous splice site mutation in the TDP2 gene. Western blot analysis did not detect TDP2 protein in patient primary skin fibroblasts. Patient fibroblasts showed an inability to rapidly repair topoisomerase-induced DNA double-strand breaks in the nucleus and also showed a profound hypersensitivity to this type of DNA damage. Complementation of patient cells with recombinant human TDP2 restored normal rates of nuclear DSB repair. Sources: Expert list |

The mutation segregated with the disorder in the family. In vitro functional expression studies in CHO cells (AP-1 cells) showed that the mutation caused decreased levels of protein expression and reduced oligosaccharide maturation/glycosylation compared to wildtype, indicating impaired posttranslational processing. Subcellular localization studies indicated that protein trafficking was unaffected by the mutation. However, examination of the trans-Golgi compartment suggested a gain-of-function effect and a perturbation of glycosylation of secretory cargo. Serum transferrin studies in 1 patient suggested a glycosylation defect. Sources: Literature |

Affected individuals shared a homozygous 10-bp deletion immediately upstream of the last exon of the PISD gene. In HEK293T cells, this variant led to aberrant splicing of PISD transcripts. 1 family with 2 sisters with congenital cataracts, short stature, and white matter changes identified compound heterozygous variants in the PISD gene.

In vitro functional expression studies in HEK293 cells showed that the mutant subunit was expressed at the surface and incorporated into the channel, but the mutant channel was 10 times more sensitive to GABA compared to wildtype. This increased sensitization resulted in increased receptor desensitization to GABA, with a reduced maximal GABA-evoked current and impaired capacity to pass GABAergic chloride current.
