Variant summary

Our verdict is Likely benign. Variant got -5 ACMG points: 3P and 8B. PM2PP2BP4_StrongBS1

The NM_001242896.3(DEPDC5):c.3241A>C(p.Thr1081Pro) variant causes a missense change. The variant allele was found at a frequency of 0.000173 in 1,611,366 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T1081I) has been classified as Uncertain significance.

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 Likely_benign. Variant got -5 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=0.051430076).

BS1

Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.000164 (25/152278) while in subpopulation NFE AF= 0.000353 (24/68016). AF 95% confidence interval is 0.000243. There are 0 homozygotes in gnomad4. There are 15 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
