This sequence change creates a premature translational stop signal (p.Tyr1479*) in the CCDC141 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 52 amino acid(s) of the CCDC141 protein. This variant is present in population databases (rs539116633, gnomAD 0.2%), and has an allele count higher than expected for a pathogenic variant. This variant has not been reported in the literature in individuals affected with CCDC141-related conditions. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
