Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV000411545 SCV000918585 likely pathogenic Wilson disease 2018-02-08 criteria provided, single submitter clinical testing Variant summary: ATP7B c.1820dupA (p.Phe608ValfsX2) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been classified as pathogenic by our laboratory (eg. c.2009_2015delATATGCT, p.Tyr670fsX1; c.2165dupT, p.Arg723fsX32; c.2304dupC, p.Met769fsX26). The variant was absent in 120764 control chromosomes (ExAC). The variant, c.1820dupA, has been reported in the literature in individuals affected with Wilson Disease (Dong_2016, Fan_2004). These data indicate that the variant may be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. One clinical diagnostic laboratory has submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation, and has a classification of likely pathogenic. Based on the evidence outlined above, the variant was classified as likely pathogenic.
