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]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -12 ACMG points.

PVS1
Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.13684872 fraction of the gene. Cryptic splice site detected, with MaxEntScore 5.2, offset of 6, new splice context is: atttcttctttatgttcaAGagg. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.
BP6
Variant 15-43632936-T-A is Benign according to our data. Variant chr15-43632936-T-A is described in ClinVar as [Benign]. Clinvar id is 402497.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BA1
GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.704 is higher than 0.05.
