Genes linked to Familial focal epilepsy with variable foci
DEPDC5: GATOR1 complex protein DEPDC5
It is part of the GATOR1 complex, which restrains mTORC1 activity when amino acids are limited. Loss-of-function variants cause focal epilepsy with variable penetrance and can contribute to focal cortical dysplasia through somatic second-hit events.
1 disease-causing and 828 uncertain variants in DEPDC5 are linked to Familial focal epilepsy with variable foci.
Known disease-causing variants in Familial focal epilepsy with variable foci

About this data
Variant–disease links come from ClinVar, Open Targets and UniProt, pooled from the latest public CATVariant analysis of each human protein. Evidence scores use the ACMG/AMP Bayesian points scale with computable criteria only (position among known disease variants, rarity in gnomAD, calibrated predictors, deep mutational scanning); there is no family or patient data, so they prioritise variants for expert review and never classify them.
