Callosome v0.523 SRPK3 Zornitza Stark gene: SRPK3 was added
gene: SRPK3 was added to Callosome. Sources: Literature
Mode of inheritance for gene: SRPK3 was set to X-LINKED: hemizygous mutation in males, biallelic mutations in females
Publications for gene: SRPK3 were set to 38429495; 39073169
Phenotypes for gene: SRPK3 were set to Neurodevelopmental disorder, MONDO:0700092, SRPK3-related
Review for gene: SRPK3 was set to GREEN
Added comment: PMID 39073169: 9 individuals from 5 unrelated families reported with 4 missense and 1 putative truncating variant and a neurodevelopmental phenotype. The 8 patients ascertained postnatally shared common clinical features including intellectual disability, agenesis of the corpus callosum, abnormal eye movement, and ataxia. A ninth case, ascertained prenatally, had a complex structural brain phenotype. Supportive animal model data (mouse and zebrafish).

Callosome v0.516 SNF8 Chern Lim gene: SNF8 was added
gene: SNF8 was added to Callosome. Sources: Literature
Mode of inheritance for gene: SNF8 was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: SNF8 were set to 38423010
Phenotypes for gene: SNF8 were set to Severe developmental delay, epileptic encephalopathy, brain MRI abnormality; intellectual disability, childhood-onset optic atrophy, ataxia
Review for gene: SNF8 was set to GREEN
gene: SNF8 was marked as current diagnostic
Added comment: PMID: 38423010
- Nine individuals from six families presenting with a spectrum of neurodevelopmental/neurodegenerative features caused by bi-allelic variants in SNF8. In total, three putative LoF variants and four missense variants were identified.
- The phenotypic spectrum included four individuals with severe developmental and epileptic encephalopathy, massive reduction of white matter, hypo-/aplasia of the corpus callosum, neurodevelopmental arrest, and early death. A second cohort shows a milder phenotype with intellectual disability, childhood-onset optic atrophy, or ataxia. All mildly affected individuals shared the same hypomorphic variant, c.304G>A (p.Val102Ile) as compound heterozygous.
- Functional studies using fibroblasts derived from patients and zebrafish model showed LoF is the disease mech.
