Genes affected

ZP2 (HGNC:13188): (zona pellucida glycoprotein 2) The zona pellucida is an extracellular matrix that surrounds the oocyte and early embryo. It is composed of three glycoproteins with various functions during fertilization and preimplantation development. The glycosylated mature peptide is one of the structural components of the zona pellucida and functions in secondary binding and penetration of acrosome-reacted spermatozoa. Female mice lacking this gene do not form a stable zona matrix and are sterile. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2014]

The c.1814A>C (p.H605P) alteration is located in exon 15 (coding exon 15) of the ZP2 gene. This alteration results from a A to C substitution at nucleotide position 1814, causing the histidine (H) at amino acid position 605 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
