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]

Submissions by phenotype

Primary ciliary dyskinesia Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeDec 07, 2023This 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. -
