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]

Collection Method:clinical testing

The c.995A>T (p.D332V) alteration is located in exon 8 (coding exon 8) of the ZPBP gene. This alteration results from a A to T substitution at nucleotide position 995, causing the aspartic acid (D) at amino acid position 332 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
