OMIA 001540-9615 : Ciliary dyskinesia, primary, CCDC39-related in Canis lupus familiaris
Previously, references to case reports of dogs with primary ciliary dyskinesia with unknown genetic cause were listed here, but these have been moved to the generic entry for this disease [3/6/2022].Mapping: By conducting a GWAS on 5 affected and 15 control Old English Sheepdogs (that all traced back to a common ancestor), each genotyped with an Affymetrix v2.0 Canine SNP chip, Merveille et al. (2011), from the LUPA consortium, identified a 15Mb region of autozygosity on chromosome CFA34. Molecular basis: Sequencing of the six most-likely candidate genes in the CFA34 candidate region (see Mapping section) region identified a nonsense mutation in the CCDC39 gene, which encodes coiled-coil domain-containing protein 39. By searching for CCDC39 mutations in PCD cases in humans (where PCD is a heterogeneous inherited disorder), they were able to identify a new cause of human PCD. This study highlights the power of canine genomic studies to inform knowledge of human inherited disorders that are genetically heterogeneous. Clinical features: As reported by Merveille et al. (2014), "Clinical findings were recurrent nasal discharge and cough, pyrexia, leucocytosis, and bronchopneumonia." Prevalence: After genotyping "578 OES [Old English Sheepdogs], including 28 affected and 550 clinically healthy dogs" for the mutation discovered by Merveille et al. (2011) (see Molecular section), Merveille et al. (2014) reported that ""The mutation was more frequent in nonrandomly selected European OES population with a higher proportion of carriers (19%) compared to non-European dogs (7%). Breed: Old English Sheepdog. Associated gene:

By default, variants are sorted chronologically by year of publication, to provide a historical perspective. Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column headers.
WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.
Since October 2021, OMIA includes a semiautomated lift-over pipeline to facilitate updates of genomic positions to a recent reference genome position. These changes to genomic positions are not always reflected in the ‘acknowledgements’ or ‘verbal description’ fields in this table.
