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 Gene-Disease associations (from GenCC):

• spermatogenic failure 46

  Inheritance: AR Classification: STRONG Submitted by: ClinGen, Labcorp Genetics (formerly Invitae)
• spermatogenic failure 5

  Inheritance: AR Classification: MODERATE Submitted by: Franklin by Genoox
• primary ciliary dyskinesia

  Inheritance: AR Classification: NO_KNOWN Submitted by: ClinGen
