Abstract
ZP1 is a critical glycoprotein in the formation of the zona pellucida. It plays an indispensable role in the maturation of oocytes. To identify the causative gene of empty follicle syndrome (EFS) in a patient from a consanguineous family, whole-exome sequencing was performed in the proband. We identified a novel homozygous nonsense mutation c.1260C > G (p. Tyr420X) in the ZP1 gene from two primary infertile patients. Western blot showed that Y420X mutation in ZP1 gene produced a truncated protein. However, the mutation had no significant effect on subcellular localization of the mutant protein. Our findings confirmed the important role of the ZP1 gene in human female reproduction, enriched the mutation spectrums of ZP1 gene, and expanded its applications in the clinical and molecular diagnoses of EFS.
