Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 2P and 3B. PM2 BP4_Moderate BP7

The NM_001370.2(DNAH6):​c.873C>A​(p.Ser291Ser) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. S291S) has been classified as Benign.

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: Likely_benign. The variant received -1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.31).
• BP7: Synonymous conserved (PhyloP=0.457 with no splicing effect.
