RCV003042677 | SCV003337431 | pathogenic | Seizures, benign familial infantile, 3; Developmental and epileptic encephalopathy, 11 | 2023-08-18 | criteria provided, single submitter | clinical testing | This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 879 of the SCN2A protein (p.Gly879Arg). Information on the frequency of this variant in the gnomAD database is not available, as this variant may be reported differently in the database. This missense change has been observed in individual(s) with clinical features of developmental and epileptic encephalopathy (PMID: 25473036, 35417276; Invitae; external communication). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 2114224). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. For these reasons, this variant has been classified as Pathogenic. |
