Genes affected

RSPH3 (HGNC:21054): (radial spoke head 3) The protein encoded by this gene acts as a protein kinase A anchoring protein. Mutations in this gene cause primary ciliary dyskinesia; a disorder characterized by defects of the axoneme in motile cilia and sperm flagella. The homolog of this gene was first identified in the blue-green algae Chlamydomonas as encoding a radial spoke protein that formed a structural component of motile cilia and flagella. Alternate splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Dec 2016]

The c.1057C>T (p.R353W) alteration is located in exon 5 (coding exon 5) of the RSPH3 gene. This alteration results from a C to T substitution at nucleotide position 1057, causing the arginine (R) at amino acid position 353 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 353 of the RSPH3 protein (p.Arg353Trp). This variant is present in population databases (rs755822557, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with RSPH3-related conditions. ClinVar contains an entry for this variant (Variation ID: 566567). 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 disruptive. 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. -
