Genes affected

CATSPER2 (HGNC:18810): (cation channel sperm associated 2) This gene encodes a member of a family of cation channel proteins that localize to the flagellum of spermatozoa. Defects at this locus causes male infertility. Alternatively spliced transcript variants have been observed at this locus. Readthrough transcription originates upstream of this locus in diphosphoinositol pentakisphosphate kinase 1 pseudogene 1 and is represented by GeneID:110006325. Related pseudogenes are found next to this locus on chromosome 15 and on chromosome 5. [provided by RefSeq, Mar 2017]

The c.1175A>C (p.D392A) alteration is located in exon 10 (coding exon 9) of the CATSPER2 gene. This alteration results from a A to C substitution at nucleotide position 1175, causing the aspartic acid (D) at amino acid position 392 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
