Genes affected

ODAD3 (HGNC:28303): (outer dynein arm docking complex subunit 3) This gene encodes a protein containing coiled-coil domains. The encoded protein functions in outer dynein arm assembly and is required for motile cilia function. Mutations in this gene result in primary ciliary dyskinesia. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Oct 2014]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM4: Nonframeshift variant in NON repetitive region in NM_145045.5.

In summary, this variant is a novel in-frame deletion with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. Experimental studies and prediction algorithms are not available for this variant, and the functional significance of the deleted amino acids is currently unknown. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a CCDC151-related disease. This sequence change deletes 21 nucleotides from exon 6 of the CCDC151 mRNA (c.767_787delTGAGGACCAAACATGAGCTGG). This leads to the deletion of 7 amino acid residues in the CCDC151 protein (p.Val256_Leu262del) but otherwise preserves the integrity of the reading frame. -
