Genes affected

GAPDHS (HGNC:24864): (glyceraldehyde-3-phosphate dehydrogenase, spermatogenic) This gene encodes a protein belonging to the glyceraldehyde-3-phosphate dehydrogenase family of enzymes that play an important role in carbohydrate metabolism. Like its somatic cell counterpart, this sperm-specific enzyme functions in a nicotinamide adenine dinucleotide-dependent manner to remove hydrogen and add phosphate to glyceraldehyde 3-phosphate to form 1,3-diphosphoglycerate. During spermiogenesis, this enzyme may play an important role in regulating the switch between different energy-producing pathways, and it is required for sperm motility and male fertility.

The c.263G>A (p.R88H) alteration is located in exon 3 (coding exon 3) of the GAPDHS gene. This alteration results from a G to A substitution at nucleotide position 263, causing the arginine (R) at amino acid position 88 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
