This variant is predicted to cause a frameshift, which alters the protein’s amino acid sequence beginning at position 1264 and lead to a premature termination codon 2 amino acids downstream. This alteration is then predicted to lead to a truncated or absent protein. Loss of function of the DSP gene is an established disease mechanism in autosomal dominant arrhythmogenic right ventricular cardiomyopathy (ARVC) and autosomal recessive Carvajal syndrome.
