Genes affected
RSPH1 (HGNC:12371): (radial spoke head component 1) This gene encodes a male meiotic metaphase chromosome-associated acidic protein. This gene is expressed in tissues with motile cilia or flagella, including the trachea, lungs, airway brushings, and testes. Mutations in this gene result in primary ciliary dyskinesia-24. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2014]

This sequence change replaces proline with leucine at codon 225 of the RSPH1 protein (p.Pro225Leu). The proline residue is weakly conserved and there is a moderate physicochemical difference between proline and leucine. This variant is present in population databases (rs201100138, ExAC 0.03%). This variant has not been reported in the literature in individuals affected with RSPH1-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest 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. -
