Integrated Genetics/Laboratory Corporation of America RCV000779817 SCV000916635 likely pathogenic Wilson disease 2018-08-15 criteria provided, single submitter clinical testing Variant summary: ATP7B c.3301_3302ins14 (p.Gly1101AlafsX25), where in the inserted sequence is CCAGGCAGTGCCAG, 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 (e.g., p.Ala1135fsX13 and p.Arg1319X). The variant was absent in 246242 control chromosomes. To our knowledge, no occurrence of c.3301_3302ins14 in individuals affected with Wilson Disease and no experimental evidence demonstrating its impact on protein function have been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as likely pathogenic.
