Fig. 1From: Novel variants in DNAH9 lead to nonsyndromic severe asthenozoospermiaVariants of DNAH9 in the two patients. a-b The two families affected by the variants in DNAH9. The red arrows indicate mutated positions in the Sanger sequencing results. c The mutated positions of DNAH9 are conserved among species. And the red arrows indicate the locations of DNAH9 variants occurred in the domains of DNAH9 protein. M, DNAH9 variant; WT, wild typeBack to article page
