LMTK2 and PARP-2 gene polymorphism and azoospermia secondary to meiotic arrest.

ABSTRACT:

Purpose

To investigate whether the human LMTK2 and PARP-2 gene defects are associated with azoospermia by meiotic arrest, mutational analysis was performed on Japanese men with azoospermia.

Methods

Via direct sequencing, mutational screening was carried out on the exon region of the genes, using genomic DNAs from 18 Japanese men. Statistical analysis was done on the detected single nucleotide polymorphisms (SNPs) in the patients and normal controls.

Results

Nine SNPs were detected in LMTK2 and five SNPs were detected in PARP-2. There were no significant differences in the genotype distribution and allele frequencies between the two groups in LMTK2. However, the genotype frequency of heterozygotes in SNP1 of PARP-2 was higher in the patient group. The haplotype analysi
