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 Pathogenic. Variant got 16 ACMG points.
PVS1
?
Splicing variant, LoF is a know mechanism of disease, Cryptic splice site detected, with MaxEntScore 5.8, offset of 23, new splice context is: atgGTgcgg. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.
PM2
?
Very rare variant in population databases, with high coverage;
PP3

Familial focal epilepsy with variable foci Pathogenic:1
Likely pathogenic, criteria provided, single submitter | clinical testing | Invitae | May 14, 2017 | In summary, donor and acceptor splice site variants are typically loss-of-function (PMID: 16199547), and loss-of-function variants in DEPDC5 are known to be pathogenic (PMID: 26505888). However, without additional functional and/or genetic data, this variant has been classified as Likely Pathogenic. This variant has not been reported in the literature in individuals with a DEPDC5-related disease. This sequence change affects a donor splice site in intron 13 of the DEPDC5 gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. - |
