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]

ACMG classification

Verdict is Benign. Variant got -21 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.6).
• BP6: Variant 19-48298306-G-A is Benign according to our data. Variant chr19-48298306-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 262484.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=1.15 with no splicing effect.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00554 (844/152354) while in subpopulation AFR AF= 0.0187 (779/41584). AF 95% confidence interval is 0.0176. There are 8 homozygotes in gnomad4. There are 362 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 8 AR gene
