ARUP Laboratories, Molecular Genetics and Genomics,ARUP Laboratories RCV000169240 SCV001159924 pathogenic Wilson disease 2018-08-30 criteria provided, single submitter clinical testing The ATP7B c.3263T>A; p.Leu1088Ter variant (rs753250853) has been described in several individuals with Wilson disease (Coffey 2013, Deguti 2004, Merle 2010, Vrabelova 2005). It contains an entry in ClinVar (Variation ID: 188886) and observed on only 2 alleles in the Genome Aggregation Database. This variant induces an early termination codon and is predicted to result in a truncated protein or mRNA subject to nonsense-mediated decay. Based on available information, this variant is considered pathogenic. REFERENCES Coffey A et al. A genetic study of Wilson's disease in the United Kingdom. Brain. 2013 May;136(Pt 5):1476-87.

Invitae RCV000169240 SCV001403793 pathogenic Wilson disease 2019-10-09 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Leu1088*) in the ATP7B gene. It is expected to result in an absent or disrupted protein product. This variant is present in population databases (rs753250853, ExAC 0.002%). This variant has been observed in individuals affected with Wilson disease (PMID: 15024742, 23518715,12515040, 20082719). ClinVar contains an entry for this variant (Variation ID: 188886). Loss-of-function variants in ATP7B are known to be pathogenic (PMID: 10441329, 16283883). For these reasons, this variant has been classified as Pathogenic.
