RCV001953445 | SCV002241270 | pathogenic | Early infantile epileptic encephalopathy with suppression bursts | 2022-10-08 | criteria provided, single submitter | clinical testing | For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 1456810). This sequence change creates a premature translational stop signal (p.Ser121Argfs*9) in the KCNQ2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in KCNQ2 are known to be pathogenic (PMID: 14534157, 23692823, 27779742). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with KCNQ2-related conditions. |
