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.800G>A (p.R267H) alteration is located in exon 4 (coding exon 4) of the RSPH3 gene. This alteration results from a G to A substitution at nucleotide position 800, causing the arginine (R) at amino acid position 267 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
