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

A heterozygous missense variation in exon 5 of the ZPBP gene that results in the amino acid substitution of cystine for tyrosine at codon 186 was detected. The variant was not observed in 1000 genomes and gnomAD databases. The in silico prediction of the variant is damaging by PolyPhen2, MutationTaster, SIFT, REVEL and CADD. The variant validated by sanger sequencing showed a heterozygous status in mother, whereas paternal sample was not avaliable. The reference codon is conserved across species. In summary, the variant meets our criteria to be classified as a variant of uncertain significance. -
