This variant disrupts a region of the DCLRE1C protein in which other variant(s) (p.Thr557Asnfs*21) have been determined to be pathogenic (PMID: 26476407). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. Variants that disrupt 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. This variant has not been reported in the literature in individuals affected with DCLRE1C-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change affects a donor splice site in intron 13 of the DCLRE1C gene. While this variant is not anticipated to result in nonsense mediated decay, it likely alters RNA splicing and results in a disrupted protein product.
