Genes affected

DNAH7 (HGNC:18661): (dynein axonemal heavy chain 7) DNAH7 is a component of the inner dynein arm of ciliary axonemes (Zhang et al., 2002 [PubMed 11877439]).[supplied by OMIM, Mar 2008]

DNAH7 Gene-Disease associations (from GenCC):

• ciliary dyskinesia, primary, 50

  Inheritance: AR Classification: LIMITED Submitted by: Labcorp Genetics (formerly Invitae)
• male infertility with azoospermia or oligozoospermia due to single gene mutation

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

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.04).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.603 is higher than 0.05.
