OMIA:001581-9685 : Curly coat, Devon rex in Felis catus (domestic cat)

Categories: Integument (skin) phene

Links to possible relevant human trait(s) and/or gene(s) in OMIM: 608245 (gene) , 615896 (trait)

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal recessive

Considered a defect: no

Key variant known: yes

Year key variant first reported: 2010

Species-specific name: Devon rex

Species-specific symbol: re

Inheritance: Gandolfi et al. (2010) suggested that the allelic hierarchy is best represented as KRT71(+) > KRT71(hr) > KRT71(re), where + is wild-type, hr is Sphynx hairless and re is Devon rex.

Molecular basis: Gandolfi et al. (2010) showed that the Devon rex mutation and the Sphynx hairless mutation (OMIA 001583-9685) are both due to mutations in the KRT71 gene which encodes keratin 71: "An 81-bp deletion (c.1108-4_1184del), including the last 4 bp of intron 6 and the first 77 bp of exon 7, followed by a 8-bp insertion (c.1184_1185insAGTTGGAG) and a base insertion (c.1196insT), was found to be homozygous in the two Devon Rex cats".

Breed: Devon Rex (Cat) (VBO_0100084).

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.
