ClinVar
Submissions by phenotype
Brugada syndrome Uncertain:1
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: 463270). 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 SCN10A protein function. 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. This variant is present in population databases (rs748441157, gnomAD 0.01%). This sequence change replaces proline, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 1956 of the SCN10A protein (p.Pro1956Thr). -
not provided Uncertain:1
Identified in a patient with DCM who also harbored additional cardiogenetic variants including a pathogenic SCN5A variant (PMID: 32746448); In silico analysis indicates that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 32746448) -
Cardiovascular phenotype Uncertain:1
The c.5866C>A (p.P1956T) alteration is located in exon 27 (coding exon 27) of the SCN10A gene. This alteration results from a C to A substitution at nucleotide position 5866, causing the proline (P) at amino acid position 1956 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
