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 Likely_benign. Variant got -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.87).
• BP6: Variant 19-48306328-G-C is Benign according to our data. Variant chr19-48306328-G-C is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 1800137.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=1}.

Likely benign, criteria provided, single submitter	clinical testing	Invitae	Jan 25, 2024	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Aug 26, 2019	The c.487-5C>G intronic variant results from a C to G substitution 5 nucleotides upstream from coding exon 5 in the CCDC114 gene. This nucleotide position is poorly conserved in available vertebrate species. Using the BDGP and ESEfinder splice site prediction tools, this alteration is not predicted to have any significant effect on this splice acceptor/donor site; however, direct evidence is unavailable. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
