Genes affected

CATSPERZ (HGNC:19231): (catsper channel auxiliary subunit zeta) Predicted to be involved in flagellated sperm motility; male meiotic nuclear division; and sperm capacitation. Located in cytoplasm and sperm principal piece. [provided by Alliance of Genome Resources, Apr 2022]

CATSPERZ links:

KCNK4-TEX40 (HGNC:56753): (KCNK4-CATSPERZ readthrough (NMD candidate)) This locus represents naturally occurring readthrough transcription between the neighboring KCNK4 (potassium channel subfamily K member 4) and the downstream TEX40 (testis expressed 40) chromosome 11. The readthrough transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is unlikely to produce a protein product. [provided by RefSeq, Nov 2015]

Ambry Genetics

Oct 28, 2024

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
