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]

DNAH10OS (HGNC:37121): (dynein axonemal heavy chain 10 opposite strand)

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 Benign. Variant got -21 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.65).
• BP6: Variant 12-123933342-C-T is Benign according to our data. Variant chr12-123933342-C-T is described in ClinVar as [Benign]. Clinvar id is 402625.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr12-123933342-C-T is described in Lovd as [Benign].
• BP7: Synonymous conserved (PhyloP=-2.63 with no splicing effect.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.316 is higher than 0.05.
