Genes affected

CATSPERG (HGNC:25243): (cation channel sperm associated auxiliary subunit gamma) CATSPERG is a subunit of the CATSPER (see CATSPER1; MIM 606389) sperm calcium channel, which is required for sperm hyperactivated motility and male fertility (Wang et al., 2009 [PubMed 19516020]).[supplied by OMIM, Jul 2010]

Collection Method: clinical testing

The c.707C>T (p.S236L) alteration is located in exon 7 (coding exon 6) of the CATSPERG gene. This alteration results from a C to T substitution at nucleotide position 707, causing the serine (S) at amino acid position 236 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
