Genes affected

GPX5 (HGNC:4557): (glutathione peroxidase 5) This gene belongs to the glutathione peroxidase family. It is specifically expressed in the epididymis in the mammalian male reproductive tract, and is androgen-regulated. Unlike several other characterized glutathione peroxidases, this enzyme is not a selenoprotein, lacking the selenocysteine residue. Thus, it is selenium-independent, and has been proposed to play a role in protecting the membranes of spermatozoa from the damaging effects of lipid peroxidation and/or preventing premature acrosome reaction. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Oct 2016]

The c.605C>G (p.A202G) alteration is located in exon 5 (coding exon 5) of the GPX5 gene. This alteration results from a C to G substitution at nucleotide position 605, causing the alanine (A) at amino acid position 202 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
