Division of Human Genetics,Children's Hospital of Philadelphia RCV000185532 SCV000238407 uncertain significance Arrhythmogenic right ventricular cardiomyopathy, type 8 2014-07-17 no assertion criteria provided research This test identified a novel variant (c.274-3C>G) in the DSP gene. This gene is associated with cardiomypathies and keratodermas: arrhythmogenic right ventricular dysplasia 8 (autosomal dominant), dilated cardiomyopathy with woolly hair and keratoderma (autosomal dominant and autosomal recessive), keratosis palmoplantaris striata II (autosomal dominant) and other autosomal recessive keratodermas. The novel DSP variant occurs in the third intronic position of the splice acceptor site. Splice site mutations in this gene have previously been reported in patients with arrhythmogenic right ventricular cardiomyopathy. However, there is no evidence in the literature supporting any splicing/expression changes resulting from the variant identified in this test. Furthermore, in silico predictions are conflicting. Therefore, this variant is considered a variant of unknown significance.
