Genes affected
ACRBP (HGNC:17195): (acrosin binding protein) The protein encoded by this gene is similar to proacrosin binding protein sp32 precursor found in mouse, guinea pig, and pig. This protein is located in the sperm acrosome and is thought to function as a binding protein to proacrosin for packaging and condensation of the acrosin zymogen in the acrosomal matrix. This protein is a member of the cancer/testis family of antigens and it is found to be immunogenic. In normal tissues, this mRNA is expressed only in testis, whereas it is detected in a range of different tumor types such as bladder, breast, lung, liver, and colon. [provided by RefSeq, Jul 2008]

The c.1364G>A (p.R455Q) alteration is located in exon 8 (coding exon 8) of the ACRBP gene. This alteration results from a G to A substitution at nucleotide position 1364, causing the arginine (R) at amino acid position 455 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
