Title: Absence of a Primary Role for SCN10A Mutations in Arrhythmogenic Right Ventricular Dysplasia/Cardiomyopathy. Author: Te Riele AS, James CA, Murray B, Tichnell C, Amat-Alarcon N, Burks K, Tandri H, Calkins H, Polydefkis M, Judge DP. Journal: J Cardiovasc Transl Res; 2016 Feb; 9(1):87-9. PubMed ID: 26733327. Abstract: Prior reports have identified associations between SCN10A and cardiac disorders, such as atrial fibrillation and Brugada syndrome. We evaluated SCN10A in 151 probands with ARVD/C. In this cohort, 10 putatively pathogenic SCN10A variants were identified, including a novel frameshift insertion. Despite a known role for the encoded protein in peripheral nerve function, the proband with the frameshift variant had no discernible neurological abnormalities. Arrhythmic phenotypes were not different between those with a rare variant in SCN10A and those without. The prevalence of rare variants in SCN10A was similar among ARVD/C probands with and without a desmosome mutation and similar among healthy Caucasian controls. These results indicate the absence of a primary role for SCN10A mutations in ARVD/C.[Abstract] [Full Text] [Related] [New Search]
