Invitae RCV003595995 SCV000774465 pathogenic Myoclonic-atonic epilepsy 2023-08-04 criteria provided, single submitter clinical testing Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt SLC6A1 protein function. For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 422549). This missense change has been observed in individual(s) with clinical features of myoclonic-atonic epilepsy (PMID: 28708303, 29315614; Invitae). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 75 of the SLC6A1 protein (p.Gly75Arg).
