Genes affected

DNAH17 (HGNC:2946): (dynein axonemal heavy chain 17) Dyneins are microtubule-associated motor protein complexes composed of several heavy, light, and intermediate chains. DNAH17 is a heavy chain associated with axonemal dynein (Milisav and Affara, 1998 [PubMed 9545504]).[supplied by OMIM, Mar 2008]

DNAH17-AS1 (HGNC:48594): (DNAH17 antisense RNA 1)

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=7.9940725E-7).
• BP6: Variant 17-78495045-T-C is Benign according to our data. Variant chr17-78495045-T-C is described in ClinVar as [Benign]. Clinvar id is 402682.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.96 is higher than 0.05.
