RCV001064692 | SCV001229605 | likely pathogenic | Idiopathic generalized epilepsy; Epilepsy, idiopathic generalized, susceptibility to, 13; Epilepsy, childhood absence 4 | 2019-12-24 | criteria provided, single submitter | clinical testing | In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has been observed in individual(s) with clinical features of early infantile epileptic encephalopathy (Invitae). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (ExAC no frequency). This sequence change replaces asparagine with lysine at codon 275 of the GABRA1 protein (p.Asn275Lys). The asparagine residue is highly conserved and there is a moderate physicochemical difference between asparagine and lysine. |
