This sequence change falls in intron 38 of the DNAH5 gene. It does not directly change the encoded amino acid sequence of the DNAH5 protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs377638408, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with DNAH5-related conditions. ClinVar contains an entry for this variant (Variation ID: 238982). 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. -
The c.6444+4T>C intronic variant results from a T to C substitution 4 nucleotides after coding exon 38 in the DNAH5 gene. This nucleotide position is not well conserved in available vertebrate species. In silico splice site analysis predicts that this alteration will not have any significant effect on splicing. Based on the available evidence, the clinical significance of this alteration remains unclear. -
