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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 24, 2023The c.1999T>G (p.S667A) alteration is located in exon 17 (coding exon 17) of the ZP2 gene. This alteration results from a T to G substitution at nucleotide position 1999, causing the serine (S) at amino acid position 667 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
