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]

The c.94A>G (p.T32A) alteration is located in exon 2 (coding exon 2) of the TEX40 gene. This alteration results from a A to G substitution at nucleotide position 94, causing the threonine (T) at amino acid position 32 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
