Variant summary: The ATP7B c.1947-4C>T variant causes a missense change involving the alteration of a non-conserved intronic nucleotide. Mutation taster predicts a damaging outcome for this variant. 5/5 splice prediction tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. This variant was found in 159/275932 control chromosomes including two homozygous occurrences (gnomAD), predominantly observed in the East Asian subpopulation at a frequency of 0.008075 (152/18824). This frequency is about 1.5 times the estimated maximal expected allele frequency of a pathogenic ATP7B variant (0.0054006), suggesting this is possibly a benign rare polymorphism found primarily in the populations of East Asian origin. Two studies report this variant as a polymorphism, without clearly stating if it was found in WD patients or controls (Kim_1998, Kim_1998). One clinical diagnostic laboratory has classified this variant as likely benign. Taken together, this variant is classified as VUS-possibly benign.
