The absence of a primary role for SCN10A mutations in arrhythmogenic right ventricular dysplasia/cardiomyopathy was reported and it has previously been noted that despite a known role for the encoded protein in peripheral nerve function, the proband with the SCN10A mutation had no discernible neurological abnormalities33. The gene discussed is SCN10A; the disease is Arrhythmogenic right ventricular dysplasia.
