| Invitae | RCV003589571 | SCV004250902 | likely pathogenic | Early infantile epileptic encephalopathy with suppression bursts | 2023-05-07 | 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. 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on SPTAN1 protein function. This missense change has been observed in individual(s) with SPTAN1-related conditions (PMID: 34489640). In at least one individual the variant was observed to be de novo. This variant is present in population databases (no rsID available, gnomAD 0.003%). This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 532 of the SPTAN1 protein (p.Lys532Arg). |
