GeneDx RCV000599470 SCV000710275 pathogenic not provided 2017-12-15 criteria provided, single submitter clinical testing The c.491_492delCCins15 pathogenic variant in the DSP gene has not been reported to our knowledge. However,this variant causes a shift in reading frame starting at codon alanine 164, changing it to a glutamic acid, and creating apremature stop codon at position 23 of the new reading frame, denoted p.Ala164GlufsX23. This pathogenic variant isexpected to result in either an abnormal, truncated protein product or loss of protein from this allele through nonsensemediatedmRNA decay. Other downstream frameshift variants in the DSP gene have been reported in the Human GeneMutation Database in association with cardiomyopathy (Stenson et al., 2014), indicating that loss of function is amechanism of disease for this gene. Furthermore, the c.491_492delCCins15 variant has not been observed in largepopulation cohorts (Lek et al., 2016).
