Labcorp Genetics (formerly Invitae), Labcorp RCV000638680 SCV000760220 uncertain significance Brugada syndrome 2024-10-26 criteria provided, single submitter clinical testing This sequence change replaces isoleucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 1593 of the SCN10A protein (p.Ile1593Phe). This variant is present in population databases (rs762600386, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with SCN10A-related conditions. ClinVar contains an entry for this variant (Variation ID: 532077). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt SCN10A protein function with a negative predictive value of 80%. 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.

Ambry Genetics RCV002334095 SCV002635721 uncertain significance Cardiovascular phenotype 2024-08-12 criteria provided, single submitter clinical testing The p.I1593F variant (also known as c.4777A>T), located in coding exon 27 of the SCN10A gene, results from an A to T substitution at nucleotide position 4777. The isoleucine at codon 1593 is replaced by phenylalanine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. The evidence for this gene-disease relationship is limited; therefore, the clinical significance of this alteration is unclear.
