DNAH3 and Infertility: In this study, we identified biallelic variants of DNAH3 (p.Gly1715Ser and p.Asp2493Asn, p.Phe2325Leu and p.Arg2991Cys, and p.Trp3420X and p.Arg3480Gln) in three unrelated infertile men whose spermatozoa displayed multiple morphological abnormalities of the flagella and decreased motility.
