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

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 6 ACMG points.

PVS1
Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.043624163 fraction of the gene. Cryptic splice site detected, with MaxEntScore 4.5, offset of 1, new splice context is: tggacttccctccttgcaAGgag. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.
PM2
Very rare variant in population databases, with high coverage;
PP5
Variant 19-11430777-C-T is Pathogenic according to our data. Variant chr19-11430777-C-T is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 1959852.Status of the report is criteria_provided_single_submitter, 1 stars.

This sequence change affects an acceptor splice site in intron 2 of the CCDC151 gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in CCDC151 are known to be pathogenic (PMID: 25192045). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with CCDC151-related conditions. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -
