| Mendeliome v1.2184 | HMGCS1 |
Zornitza Stark gene: HMGCS1 was added gene: HMGCS1 was added to Mendeliome. Sources: Literature Mode of inheritance for gene: HMGCS1 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: HMGCS1 were set to 39531736 Phenotypes for gene: HMGCS1 were set to Rigid spine syndrome, MONDO:0019951, HMGCS1-related Review for gene: HMGCS1 was set to GREEN Added comment: Five individuals from four families reported. All individuals presented with spinal rigidity primarily affecting the cervical and dorsolumbar regions, scoliosis, and respiratory insufficiency. Creatine kinase levels were variably elevated. The clinical course worsened with intercurrent disease or certain drugs in some; one individual died from respiratory failure following infection. Muscle biopsies revealed irregularities in oxidative enzyme staining with occasional internal nuclei and rimmed vacuoles. HMGCS1 encodes a critical enzyme of the mevalonate pathway. Notably, biallelic hypomorphic variants in downstream enzymes including HMGCR and GGPS1 are associated with muscular dystrophy. Hmgcs1 mutant zebrafish displayed severe early defects, including immobility at 2 days and death by day 3 post-fertilisation and were rescued by HMGCS1 mRNA. Four variants tested (S447P, Q29L M70T, and C268S) have reduced function compared to wildtype HMGCS1 in zebrafish rescue assays Sources: Literature |

| Mendeliome v1.28 | SPTAN1 | Zornitza Stark edited their review of gene: SPTAN1: Added comment: Leveille et al (2019) - 2 patients with HSP with biallelic missense SPTAN1 variants Previously described zebrafish, mouse, and rat animal models of SPTAN1 deficiency, all consistently showing axonal degeneration, fitting the pathological features of HSP in humans. Xie et al (2022) - 1 patient with complicated HSP and homozygous SPTAN1 mutation. Healthy parents and sister all carried the heterozygous mutation. Van de Vondel et al (2022) - 22 patients from 14 families with five novel heterozygous SPTAN1 variants. Presentations ranged from cerebellar ataxia, intellectual disability, epilepsy, and spastic paraplegia. A recurrent missense mutation (p.Arg19Trp) in 15 patients with spastic paraplegia. Through protein modeling they showed that mutated amino acids are located at crucial interlinking positions, interconnecting the three-helix bundle of a spectrin repeat.; Changed publications: 20493457, 22258530, 32811770, 35150594, 34526651, 31515523; Changed phenotypes: Developmental and epileptic encephalopathy 5, MIM# 613477, Hereditary spastic paraplegia MONDO:0019064, SPTAN1-related; Changed mode of inheritance: BOTH monoallelic and biallelic, autosomal or pseudoautosomal | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Mendeliome v0.14650 | ADD1 |
Chirag Patel gene: ADD1 was added gene: ADD1 was added to Mendeliome. Sources: Literature Mode of inheritance for gene: ADD1 was set to BOTH monoallelic and biallelic (but BIALLELIC mutations cause a more SEVERE disease form), autosomal or pseudoautosomal Publications for gene: ADD1 were set to PMID: 34906466 Phenotypes for gene: ADD1 were set to Intellectual disability, corpus callosum dysgenesis, and ventriculomegaly; no OMIM # Review for gene: ADD1 was set to GREEN Added comment: 4 unrelated individuals affected by ID and/or complete or partial agenesis of corpus callosum, and enlarged lateral ventricles. WES found loss-of-function variants - 1 recessive missense variant and 3 de novo variants. The recessive variant is associated with ACC and enlarged lateral ventricles, and the de novo variants were associated with complete or partial agenesis of corpus callosum, mild ID and attention deficit. Human variants impair ADD1 protein expression and/or dimerization with ADD2. Add1 knockout mice recapitulate corpus callosum dysgenesis and ventriculomegaly phenotypes. Three adducin genes (ADD1, ADD2, and ADD3) encode cytoskeleton proteins that are critical for osmotic rigidity and cell shape. ADD1, ADD2, and ADD3 form heterodimers (ADD1/ADD2, ADD1/ADD3), which further form heterotetramers. Adducins interconnect spectrin and actin filaments to form polygonal scaffolds beneath the cell membranes and form ring-like structures in neuronal axons. Adducins regulate mouse neural development, but their function in the human brain is unknown Sources: Literature |

| Mendeliome v0.11540 | NDUFAF4 |
Krithika Murali edited their review of gene: NDUFAF4: Added comment: 3 unrelated families reported with patient-specific functional evidence provided for each. PMID: 32949790 - report two siblings with facial dysmorphism and lactic acidosis diagnosed neonatally with subsequent fatal early encephalopathy with apneic episodes, irritability, central hypoventilation, liver involvement and hyperammonemia. Cerebral white matter anomalies reported in one patient and cardiomyopathy in the other. WES identified homozygous nonsense NDUFAF4 variants with absent NDUFAF4 expression in patient fibroblasts. OXPHOS assembly studies demonstrated almost undetectable levels of fully assembled complex I and complex I–containing supercomplexes and an abnormal accumulation of SCIII2IV1 supercomplexes. Morphologically, fibroblasts showed rounder mitochondria and a diminished degree of branching of the mitochondrial network. PMID: 28853723 - report one patient born at 38 weeks after IOL for IUGR. Presented age 7 months with developmental regression, growth failure and central hypotonia. Brain MRI revealed diffuse bilateral signal alterations in the basal ganglia and thalami and an EEG showed generalized slowing with multifocal spikes consistent with an epileptogenic focus. Homozygous missense NDUFAF4 variants identified. Lentiviral complementation of patient fibroblasts with wild-type NDUFAF4 rescued complex I deficiency and assembly defect PMID 18179882 - report multiple affected individuals from one family. Most presented soon after birth with severe metabolic acidosis and high plasma lactate levels. Patients who survived longer were repeatedly admitted because of exacerbation of the acidosis during intercurrent infections. One long-term survivor had profound ID.; Changed publications: 32949790, 28853723, 18179882 |
