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]

Ambry Genetics

Nov 21, 2024

The c.1452G>A (p.M484I) alteration is located in exon 12 (coding exon 11) of the CATSPER2 gene. This alteration results from a G to A substitution at nucleotide position 1452, causing the methionine (M) at amino acid position 484 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
