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]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The missense variant c.1385A>G (p.Tyr462Cys) in DEPDC5 gene has been submitted to ClinVar as a Variant of Uncertain Significance. The c.1385A>G (p.Tyr462Cys) variant has not been reported in the literature in individuals with DEPDC5-related disease. The c.1385A>G (p.Tyr462Cys) variant is reported with the allele frequency (0.001%) in the gnomAD Exomes and is novel (not in any individuals) in 1000 Genomes. The amino acid Tyr at position 462 is changed to a Cys changing protein sequence and it might alter its composition and physico-chemical properties. The variant is predicted to be damaging by both SIFT and PolyPhen2. The residue is conserved across species. The amino acid change p.Tyr462Cys in DEPDC5 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Variant of Uncertain Significance (VUS). -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 462 of the DEPDC5 protein (p.Tyr462Cys). This variant is present in population databases (rs747546981, gnomAD 0.006%). This missense change has been observed in individual(s) with frontal lobe epilepsy (PMID: 30093711). ClinVar contains an entry for this variant (Variation ID: 466451). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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. -
