Invitae RCV000641804 SCV000763454 uncertain significance Dilated cardiomyopathy with woolly hair and keratoderma; Arrhythmogenic right ventricular cardiomyopathy, type 8 2017-11-18 criteria provided, single submitter clinical testing This sequence change falls in intron 1 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). This variant has not been reported in the literature in individuals with DSP-related disease. Nucleotide substitutions within the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing, but this prediction has not been confirmed by published transcriptional studies. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
