Fig. 3From: Identification of deleterious variants in patients with male infertility due to idiopathic non-obstructive azoospermiaVariants of DMRT1 in NOA22 and NOA25. A The families affected by the variants in DMRT1. The red arrows indicate mutated positions in the Sanger sequencing results. B Testicular histopathology. C The mutated positions of DMRT1 are conserved among species (red arrows). And the dotted line indicates the position of DMRT1 variants in DMRT1 protein. M, mutation; WT, wild typeBack to article page
