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]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 0 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), DEPDC5. . Gene score misZ 2.6501 (greater than the threshold 3.09). Trascript score misZ 3.7275 (greater than threshold 3.09). GenCC has associacion of gene with focal epilepsy, Brugada syndrome, epilepsy, familial focal, with variable foci 1, familial focal epilepsy with variable foci, autosomal dominant epilepsy with auditory features, autosomal dominant nocturnal frontal lobe epilepsy.
BP4
Computational evidence support a benign effect (MetaRNN=0.11032802).
BS1
Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.0000219 (32/1461606) while in subpopulation SAS AF= 0.000336 (29/86254). AF 95% confidence interval is 0.00024. There are 0 homozygotes in gnomad4_exome. There are 23 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

This variant is present in population databases (rs750919199, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with DEPDC5-related conditions. ClinVar contains an entry for this variant (Variation ID: 534792). 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. -
