It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. This variant is present in population databases (rs748810737, ExAC 0.002%). This variant has been observed in individuals affected with non-syndromic deafness or Usher syndrome (PMID: 27460420, 28944237). ClinVar contains an entry for this variant (Variation ID: 265980). 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. Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in USH2A are known to be pathogenic (PMID: 10729113, 10909849, 20507924, 25649381). 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.
