Genes affected

DEPDC5 (HGNC:18423): (DEP domain containing 5, GATOR1 subcomplex subunit) This gene encodes a member of the IML1 family of proteins involved in G-protein signaling pathways. The mechanistic target of rapamycin complex 1 (mTORC1) pathway regulates cell growth by sensing the availability of nutrients. The protein encoded by this gene is a component of the GATOR1 (GAP activity toward Rags) complex which inhibits the amino acid-sensing branch of the mTORC1 pathway. Mutations in this gene are associated with autosomal dominant familial focal epilepsy with variable foci. A single nucleotide polymorphism in an intron of this gene has been associated with an increased risk of hepatocellular carcinoma in individuals with chronic hepatitis C virus infection. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2014]

This sequence change replaces serine, which is neutral and polar, with arginine, which is basic and polar, at codon 1073 of the DEPDC5 protein (p.Ser1073Arg). This variant is present in population databases (rs754608531, gnomAD 0.006%). This missense change has been observed in individual(s) with familial focal epilepsy with variable foci (PMID: 23542697). ClinVar contains an entry for this variant (Variation ID: 264760). Algorithms developed to predict the effect of variants on protein structure and function are not available or were not evaluated for this variant. Experimental studies are conflicting or provide insufficient evidence to determine the effect of this variant on DEPDC5 function (PMID: 25366275). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
