Invitae RCV000666959 SCV000933934 likely pathogenic Wilson disease 2018-12-27 criteria provided, single submitter clinical testing This sequence change falls in intron 8 of the ATP7B gene. It does not directly change the encoded amino acid sequence of the ATP7B protein, but it affects a nucleotide within the consensus splice site of the intron. This variant is present in population databases (rs776572343, ExAC 0.009%). This variant has been observed in individuals affected with Wilson disease (PMID: 18373411, Invitae). ClinVar contains an entry for this variant (Variation ID: 551811). Nucleotide substitutions within the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site, but this prediction has not been confirmed by published transcriptional studies. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
