Invitae RCV000555656 SCV000641284 uncertain significance Dilated cardiomyopathy with woolly hair and keratoderma; Arrhythmogenic right ventricular cardiomyopathy, type 8 2017-03-26 criteria provided, single submitter clinical testing This sequence change falls in intron 12 of the DSP gene. It does not directly change the encoded amino acid sequence of the DSP protein, but it affects a nucleotide within the consensus splice site of the intron. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a DSP-related disease. Nucleotide substitutions within the consensus splice site are relatively common causes of aberrant splicing (PMID: 17576681, 9536098) but according to multiple splice site algorithms this particular variant is not predicted to significantly affect splicing. These predictions have not been confirmed by published functional studies. In summary, this variant is a novel  intronic change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance.
