Mendeliome v0.2280 KCNJ11 Elena Savva edited their review of gene: KCNJ11: Added comment: Congenital hyperinsulinism (HI) variants are generally reported in heterozygous patients where they also carry a somatic 2nd hit, or have isodisomy of the paternal allele (focal HI), or in bilallelic patients (diffuse HI). 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

Added comment: Single clinical paper (30804514) reports variant in affected mother and child (de novo in mother) and in a separate unrelated female (de novo) with spondylo-epiphyseal dysplasia. Mouse model (21576357) deletion of gene causes impaired longitudinal bone growth. Separate mouse model studies by same authors as clinical paper above (30804514) showed phenotype of mice with same mutation in this gene consistent with the skeletal dysplasia features of patients with the n.24A-G mutation, suggestive of neomorphic effects (mutation produces both loss-of-function and gain-of-function effects.)

Review for gene: TDP2 was set to GREEN
Added comment: ID is part of the phenotype: 4 families with 6 affected patients, with functional evidence.

1 family with 3 affected sibs with homozygous splice site mutation in the TDP2 gene. 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.

Added comment: 6 males from 2 unrelated families with hemizygous missense mutation in the SLC9A7 gene. 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.

Added comment: Reviewed by E Palmer: Ambrosino et al described 2 unrelated females with de novo variants in KCNT2. The first patient had the variant p.(Arg190His) had with West syndrome followed by Lennox-Gastaut syndrome , the second patient had the variant p.(Arg190Pro) and DEE with migrating focal seizures. Both variants were absent gnomad and had supportive in silico support for pathogenicity. In an electrophisological model both KCNT2 R190P and KCNT2 R190H increased maximal current density and shifted toward more negative membrane potential values the activation curve of KCNT2 channels, consistent with gain of function effects. PMID: 29740868.

Gururaj et al describe one male with de novo variant in KCNT2 p. (Phe240Leu) and early infantile epileptic encephalopathy. he variant was absent gnomad and supportive evidence of pathogenicity This variant was electrophysiologically modelled and revealed that the variant resulted in a 'change in function' demonstrating unusual altered selectivity in KNa channels.PMID: 29069600.

Western blot analysis of proteins overexpressed in the Drosophila fat body showed strongly reduced levels of the SCAMP p.Gly302Trp protein compared with the wild-type protein, indicating that the mutant either reduced expression or increased turnover of the protein. The expression of the fly homologue of the human SCAMP5 p.Gly180Trp mutation caused similar eye and neuronal phenotypes as the expression of SCAMP RNAi, suggesting a dominant-negative effect.

Mendeliome v0.308 PISD Zornitza Stark commented on gene: PISD: 4 individuals in 2 unrelated but consanguineous families from Portugal and Brazil affected by early-onset retinal degeneration, sensorineural hearing loss, microcephaly, intellectual disability, and skeletal dysplasia with scoliosis and short stature (Liberfarb syndrome). 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. Decreased conversion of phosphatidylserine to PE in patient fibroblasts is consistent with impaired phosphatidylserine decarboxylase (PISD) enzyme activity.

Patient lymphocytes and fibroblasts showed variably decreased levels of cell surface GPI-anchored proteins, including CD16 and CD59. In vitro functional expression studies performed with some of the mutations in PIGB-null CHO cells showed that the mutant proteins were unable to fully restore expression of GPI-anchored surface proteins, consistent with a loss of function, although the mutations had variable effects.

Added comment: 9 cases with intellectual disability and craniofacial anomalies (Potocki-Shaffer syndrome), with de novo truncating variants in PHF21A. No functional evidence of variants, but PHF21A is highly expressed in the human fetal brain, which is consistent with the neurodevelopmental phenotype.

2 other unrelated individuals with translocations disrupting PHF21A. Lymphoblastoid cell lines from translocation subjects showed derepression of the neuronal gene SCN3A and reduced LSD1 occupancy at the SCN3A promoter, supporting a direct functional consequence of PHF21A haploinsufficiency on transcriptional regulation.
