This sequence change falls in intron 35 of the NUP160 gene. It does not directly change the encoded amino acid sequence of the NUP160 protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs201495092, gnomAD 0.06%). This variant has not been reported in the literature in individuals affected with NUP160-related conditions. 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 is not likely to affect RNA splicing. 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. -
