Two single nucleotide polymorphisms in PRDM9 (MEISETZ) gene may be a genetic risk factor for Japanese patients with azoospermia by meiotic arrest.

ABSTRACT:

Purpose

To investigate whether defects in human PRDM9, CDK2 and PSMC3IP are associated with azoospermia Mutational analysis was performed in Japanese patients with azoospermia caused by meiotic arrest.

Methods

Mutational screening of the coding regions of human PRDM9, CDK2 and PSMC3IP was done by direct sequencing using genomic DNA from 18 Japanese patients. Statistical analysis of the detected coding single nucleotide polymorphisms (cSNPs) in patients and normal control men was then carried out.

Results

One cSNP was detected in CDK2 and PSMC3IP. There were no significant differences in genotype distribution and allele frequencies between the patient and control groups in these two genes. However, three novel cSNPs were detected in the PRDM9. The genotype and allele f
