Species-specific name: Bobtail, bobbed tail

Species-specific description: Japanese Bobtail cats have such a shortened and kinked tail. Show-quality standards require the cat to have a tail length under 3 inches (Pollard et al., 2015). The shortened tail in this breed is caused by a different mutation and gene compared to the tailless Manx phenotype (OMIA 000975-9685).

History: "Cats with shortened and kinked tails were first recorded in the Malayan archipelago by Charles Darwin in 1868 and remain quite common today in Southeast and East Asia." (Xu et al. 2016)

Molecular basis: Lyons et al. (2016): c.5A>G; p.V2A in Japanese Bobtail Xu et al. (2016) identified the same likely causal mutation in Chinese short-tailed feral cat, and confirmed it in Japanese Bobtail.

Genetic engineering: Unknown
Have human generated variants been created, e.g. through genetic engineering and gene editing

Clinical features: Pollard et al. (2015): "radiological examinations of the entire vertebral column of kink-tailed cats indicated variation from the normal vertebral feline formula (C7, T13, L7, S3, Cd20-24), including cats with mostly one reduction of thoracic vertebrae (C7, T12, L7, S3), and an average of 15.8 caudal vertebrae. A few cats had variation in the number of cervical vertebrae. Several transitional vertebrae and anomalous ribs were noted. One cat had a bifid vertebra in the tail. Most cats had hemivertebrae that were usually included in the tail kink, one of which was demonstrated by gross pathology and histopathology. The abnormal vertebral formula or the placement of the kink in the tail did not coincide with morbidity or mortality."

Prevalence: As reported by Lyon et al. (2016): "A sub-set of cats was genotyped for the HES7 variant, supporting the variant as private to the Japanese bobtail breed."

Breed: Japanese Bobtail (Cat) (VBO_0100128).

Variants

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.
