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 -21 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.6).
• BP6: Variant 19-48311568-G-A is Benign according to our data. Variant chr19-48311568-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 262499.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=1.03 with no splicing effect.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00146 (222/152182) while in subpopulation NFE AF= 0.0024 (163/68010). AF 95% confidence interval is 0.0021. There are 1 homozygotes in gnomad4. There are 100 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
• BS2: High Homozygotes in GnomAdExome4 at 10 AR gene

Likely benign, criteria provided, single submitter	clinical testing	Ambry Genetics	Jan 22, 2018	This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
