Genes affected

RSPH9 (HGNC:21057): (radial spoke head component 9) This gene encodes a protein thought to be a component of the radial spoke head in motile cilia and flagella. Mutations in this gene are associated with primary ciliary dyskinesia 12. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Jul 2010]

This sequence change replaces proline, which is neutral and non-polar, with arginine, which is basic and polar, at codon 87 of the RSPH9 protein (p.Pro87Arg). This variant is present in population databases (rs774989438, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with RSPH9-related conditions. ClinVar contains an entry for this variant (Variation ID: 525281). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. 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. -
