Absence of a Primary Role for SCN10A Mutations in Arrhythmogenic Right Ventricular Dysplasia/Cardiomyopathy.

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 ARV
