Variations in the dynein axonemal heavy chain 17 gene (DNAH17, OMIM 610063), encoding a component of outer dynein arms (ODAs) in the ciliary axonemes, have been reported to be associated with only flagella destabilization and asthenozoospermia (Whitfield et al., 2019; Zhang et al., 2020). This evidence concerns the gene DNAH17 and Reduced sperm motility.
