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]

Primary ciliary dyskinesia

Uncertain:1Benign:1

Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Jul 05, 2022	This sequence change replaces methionine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 33 of the RSPH9 protein (p.Met33Thr). This variant is present in population databases (rs374043705, gnomAD 0.006%). 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: 575069). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The threonine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
Likely benign, criteria provided, single submitter	clinical testing	Ambry Genetics	Mar 05, 2024	This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
