Genes affected
DNAH8 (HGNC:2952): (dynein axonemal heavy chain 8) The protein encoded by this gene is a heavy chain of an axonemal dynein involved in sperm and respiratory cilia motility. Axonemal dyneins generate force through hydrolysis of ATP and binding to microtubules. [provided by RefSeq, Jan 2012]
DNAH8-AS1 (HGNC:40188): (DNAH8 antisense RNA 1)
