Genes affected

DNAH6 (HGNC:2951): (dynein axonemal heavy chain 6) This gene belongs to the dynein family, whose members encode large proteins that are constituents of the microtubule-associated motor protein complex. This complex is composed of dynein heavy, intermediate and light chains, which can be axonemal or cytoplasmic. This protein is an axonemal dynein heavy chain. It is involved in producing force for ciliary beating by using energy from ATP hydrolysis. Mutations in this gene may cause primary ciliary dyskinesia (PCD) as well as heterotaxy.

DNAH6 Gene-Disease associations (from GenCC):

• male infertility with azoospermia or oligozoospermia due to single gene mutation

  Inheritance: AR Classification: MODERATE Submitted by: King Faisal Specialist Hospital and Research Center

ACMG classification

Our verdict: Benign. The variant received -10 ACMG points.
