• Consequence: DNAH10 NM_001372106.1 missense
• Clinical Significance: Uncertain significance criteria provided, single submitter U:1
• Conservation: PhyloP100: 7.89

Genes affected

DNAH10 (HGNC:2941): (dynein axonemal heavy chain 10) Dyneins are microtubule-associated motor protein complexes composed of several heavy, light, and intermediate chains. The axonemal dyneins, found in cilia and flagella, are components of the outer and inner dynein arms attached to the peripheral microtubule doublets. DNAH10 is an inner arm dynein heavy chain (Maiti et al., 2000 [PubMed 11175280]).[supplied by OMIM, Mar 2008]

CCDC92 (HGNC:29563): (coiled-coil domain containing 92) Enables identical protein binding activity. Located in centriole; centrosome; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 5 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), DNAH10. . Gene score misZ 1.5457 (greater than the threshold 3.09). Trascript score misZ 3.4903 (greater than threshold 3.09). GenCC has associacion of gene with spermatogenic failure 56.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.9
