Genes affected

ODAD1 (HGNC:26560): (outer dynein arm docking complex subunit 1) This gene encodes a coiled-coil domain-containing protein that is a component of the outer dynein arm docking complex in cilia cells. Mutations in this gene may cause primary ciliary dyskinesia 20. [provided by RefSeq, May 2013]

ODAD1 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0039197803).
• BP6: Variant 19-48318481-C-G is Benign according to our data. Variant chr19-48318481-C-G is described in ClinVar as [Benign]. Clinvar id is 241874.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr19-48318481-C-G is described in Lovd as [Benign].
• BS1: Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.00168 (256/152282) while in subpopulation EAS AF= 0.0471 (244/5182). AF 95% confidence interval is 0.0422. There are 6 homozygotes in gnomad4. There are 141 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 6 AR gene
