DMRT1 mutations are rarely associated with male infertility

Because deletions of DMRT1 are found in XY gonadal dysgenesis, ovotesticular disorder, and male infertility, we sequenced DMRT1 in 171 male infertility patients and detected four possibly pathogenic mutations.

Abstract

Objective:

To study a potential association between male infertility and DMRT1 mutations.

Design:

Retrospective sequencing study.

Setting:

University hospital.

Patient(s):

171 patients with cryptozoospermia (sperm concentration <0.1 million/mL, n = 40) or nonobstructive azoospermia (n = 131), and 215 normozoospermic controls. Intervention(s):

Sequence analysis of DMRT1.

Main Outcome Measure(s):

Identification of rare variants in DMRT1 that are associated with male infertility.

Result(s):

In total, we detected four putative pathogenic mutations in six patients (3.5%) and less frequently in two controls (0.9%).

Conclusion(s):

Point mutations of DMRT1 may be rarely associated with male infertility.
