The ODAD1 c.1391+5G>A variant is predicted to interfere with splicing. This variant has been reported in the compound heterozygous state in an individual with primary ciliary dyskinesia (Knowles et al. 2013. PubMed ID: 23261302). This variant was shown to disrupt the adjacent GT donor site in exon 12 of ODAD1, resulting in an out-of-frame deletion of exon 12 and a premature protein termination (Knowles et al. 2013. PubMed ID: 23261302). This variant is reported in 0.049% of alleles in individuals of Ashkenazi Jewish descent in gnomAD. This variant is interpreted as pathogenic. -

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change falls in intron 12 of the CCDC114 gene. It does not directly change the encoded amino acid sequence of the CCDC114 protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs201133219, gnomAD 0.05%). This variant has been observed in individual(s) with primary ciliary dyskinesia (PMID: 23261302; internal data). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 39640). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
