Association of a TDRD1 variant with spermatogenic failure susceptibility in the Han Chinese.

ABSTRACT:

Purpose

Piwi-interacting RNAs (piRNAs) are a broad group of noncoding small RNAs that have important biological functions in germline cells and can maintain genome integrity via silencing of retrotransposons. In this study, we aimed to explore the associations between genetic variants of important genes involved in piRNA biogenesis and male infertility with spermatogenic impairment.

Methods

To this end, five single-nucleotide polymorphisms (SNPs) in the ASZ1, PIWIL1, TDRD1, and TDRD9 genes were genotyped by TaqMan allelic discrimination assays in 342 cases of nonobstructive azoospermia (NOA) and 493 controls.

Results

The SNP rs77559927 in TDRD1 was associated with a reduced risk of spermatogenic impairment. The genotypes TC and TC + CC showed odds ratios and 95 % conf
