Genes affected
RSPH10B2 (HGNC:34385): (radial spoke head 10 homolog B2) This gene encodes a protein component of the radial spoke head in flagella and motile cilia. Eukaryotic flagella and motile cilia share a common 9 + 2 structure, in which nine peripheral microtubule doublets (MTDs) surround a central-pair of microtubules (CP), with radial spokes connecting the MTDs to the CP. The radial spoke is a multi-protein complex that works as a mechanochemical transducer between the CP and the MTDs. The radial spoke contributes to the regulation of the activity of dynein motors, and thus to flagellar motility. PMID: 22754630 provides a good review of radial spokes.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 05, 2024The c.181C>T (p.R61C) alteration is located in exon 3 (coding exon 1) of the RSPH10B2 gene. This alteration results from a C to T substitution at nucleotide position 181, causing the arginine (R) at amino acid position 61 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
