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.

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), DNAH6. . Gene score misZ 3.5535 (greater than the threshold 3.09). Trascript score misZ 3.4022 (greater than threshold 3.09). GenCC has associacion of gene with male infertility with azoospermia or oligozoospermia due to single gene mutation.

BP4

Computational evidence support a benign effect (MetaRNN=0.027846336).

BP6

Variant 2-84528965-T-C is Benign according to our data. Variant chr2-84528965-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 2462267.Status of the report is criteria_provided_single_submitter, 1 stars.

Ambry Genetics

Mar 06, 2023

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
