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 Gene-Disease associations (from GenCC):

• primary ciliary dyskinesia 20

  Inheritance: AR Classification: DEFINITIVE, STRONG Submitted by: G2P, ClinGen, Labcorp Genetics (formerly Invitae)
• primary ciliary dyskinesia

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Likely_benign. The variant received -5 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.057471067).
• BS1: Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.0000212 (31/1461788) while in subpopulation MID AF = 0.00416 (24/5768). AF 95% confidence interval is 0.00287. There are 0 homozygotes in GnomAdExome4. There are 14 alleles in the male GnomAdExome4 subpopulation. Median coverage is 63. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
