Genes affected

RSPH6A (HGNC:14241): (radial spoke head 6 homolog A) The protein encoded by this gene is similar to a sea urchin radial spoke head protein. Radial spoke protein complexes form part of the axoneme of eukaryotic flagella and are located between the axoneme's outer ring of doublet microtubules and central pair of microtubules. In Chlamydomonas, radial spoke proteins are thought to regulate the activity of dynein and the symmetry of flagellar bending patterns. This gene maps to a region of chromosome 19 that is linked to primary ciliary dyskinesia-2 (CILD2). [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.1669G>A (p.V557M) alteration is located in exon 4 (coding exon 4) of the RSPH6A gene. This alteration results from a G to A substitution at nucleotide position 1669, causing the valine (V) at amino acid position 557 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
