GeneDx RCV000078053 SCV000520883 likely benign not specified 2017-12-15 criteria provided, single submitter clinical testing This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.

Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.0027 in 279784 control chromosomes, predominantly at a frequency of 0.017 within the East Asian subpopulation in the gnomAD database, including 6 homozygotes. The observed variant frequency within East Asian control individuals in the gnomAD database is approximately 3.15 fold of the estimated maximal expected allele frequency for a pathogenic variant in ATP7B causing Wilson Disease phenotype (0.0054), strongly suggesting that the variant is a benign polymorphism found primarily in populations of East Asian origin. c.3889G>A has been reported as a "polymorphism" in the literature in individuals affected with Wilson Disease. Multiple studies reported not significantly different MAF of variant in diesease vs control cohort (Dong_2016 and Hua_2016) and listed variant as polymorphism. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Five clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar without evidence for independent evaluation (2 benign, 2 likely benign and 1 VUS). Based on the evidence outlined above, the variant was classified as benign.

Illumina Clinical Services Laboratory,Illumina RCV000490530 SCV001268482 likely benign Wilson disease 2018-09-17 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.
