Overall, 8 DNAH1 variations were detected in the infertile patients; among them, 6 variations (g.52400764G>C, g.52409336C>T, g.52412620del, g.52412624C>A, g.52418050del, g.52430536del) were respectively located at 6 AAA-domains, which together with a coiled-coil stalk constitute a conserved dynein motor domain. This evidence concerns the gene DNAH1 and Infertility.
