Genes affected

ZPBP (HGNC:15662): (zona pellucida binding protein) ZPBP is one of several proteins that are thought to participate in secondary binding between acrosome-reacted sperm and the egg-specific extracellular matrix, the zona pellucida (McLeskey et al., 1998 [PubMed 9378618]).[supplied by OMIM, Aug 2008]

The c.992G>A (p.R331H) alteration is located in exon 8 (coding exon 8) of the ZPBP gene. This alteration results from a G to A substitution at nucleotide position 992, causing the arginine (R) at amino acid position 331 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
