Novel Mutation Loci Lead to Multiple Morphological Abnormalities of the Sperm Flagella and Literature Review.

The protein encoded by dynein axonemal heavy chain 1 () is a part of dynein, which regulates the function of cilia and sperm flagella. The mutant of causes the deletion of inner dynein arm 3 in the flagellum, leading to multiple morphological abnormalities of the sperm flagella (MMAF) and severe asthenozoospermia. However, instead of asthenozoospermia and MMAF, the result caused by the mutation of remains unknown.
