Genes affected

ACR (HGNC:126): (acrosin) Acrosin is the major proteinase present in the acrosome of mature spermatozoa. It is a typical serine proteinase with trypsin-like specificity. It is stored in the acrosome in its precursor form, proacrosin. The active enzyme functions in the lysis of the zona pellucida, thus facilitating penetration of the sperm through the innermost glycoprotein layers of the ovum. The mRNA for proacrosin is synthesized only in the postmeiotic stages of spermatogenesis. In humans proacrosin first appears in the haploid spermatids. [provided by RefSeq, Jul 2008]

Sep 15, 2021

The c.191C>T (p.T64M) alteration is located in exon 2 (coding exon 2) of the ACR gene. This alteration results from a C to T substitution at nucleotide position 191, causing the threonine (T) at amino acid position 64 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
