dynein axonemal heavy chain 1

From NCBI Gene:
This gene encodes an inner dynein arm heavy chain that provides structural support between the radial spokes and the outer doublet of the sperm tail. Naturally occurring mutations in this gene are associated with primary ciliary dyskinesia and multiple morphological anomalies of the flagella that result in asthenozoospermia and male infertility. Mice with a homozygous knockout of the orthologous gene are viable but have reduced sperm motility and are infertile. [provided by RefSeq, Feb 2017]
Force generating protein of cilia required for sperm flagellum motility. Produces force towards the minus ends of microtubules. Dynein has ATPase activity; the force-producing power stroke is thought to occur on release of ADP. Required in spermatozoa for the formation of the inner dynein arms and biogenesis of the axoneme (PubMed:24360805).

- SPERMATOGENIC FAILURE 18
Ciliary dyskinesia, primary, 37 (CILD37): A form of primary ciliary dyskinesia, a disorder characterized by abnormalities of motile cilia. Respiratory infections leading to chronic inflammation and bronchiectasis are recurrent, due to defects in the respiratory cilia. Some patients exhibit randomization of left-right body asymmetry and situs inversus. Primary ciliary dyskinesia associated with situs inversus is referred to as Kartagener syndrome. CILD37 inheritance is autosomal recessive. [MIM:617577]
Spermatogenic failure 18 (SPGF18): An infertility disorder caused by spermatogenesis defects and characterized by abnormally shaped spermatozoa in the semen of affected individuals. SPGF18 patients present with primary infertility and multiple morphological abnormalities of sperm flagella that result in impaired sperm mobility. Abnormalities include absent, short, coiled, bent, and irregular flagella. SPGF18 inheritance is autosomal recessive. [MIM:617576]
