Invitae RCV002967950 SCV003289713 uncertain significance Long QT syndrome 2022-12-08 criteria provided, single submitter clinical testing Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. 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 SNTA1 protein function. This variant has not been reported in the literature in individuals affected with SNTA1-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces threonine, which is neutral and polar, with lysine, which is basic and polar, at codon 370 of the SNTA1 protein (p.Thr370Lys).
