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]

Submissions by phenotype
Familial focal epilepsy with variable foci Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jan 20, 2017 | For these reasons, this variant has been classified as Pathogenic. While this particular variant has not been reported in the literature, loss-of-function variants in DEPDC5 are known to be pathogenic (PMID: 27173016). This sequence change creates a premature translational stop signal at codon 462 (p.Tyr462*) of the DEPDC5 gene. It is expected to result in an absent or disrupted protein product. - |
