Species-specific name: French rex; Gillet rex; Franz. Rex
Species-specific symbol: rex; r1
Species-specific description: See Robinson (1958, pp. 298-300).
History: This is the first of three rex mutant phenotypes to be described. As summarised by Diribarne et al. (2011), "In 1919 in the Pays de Loire French region, a mutant phenotype with soft hair was observed by a breeder in a litter of wild gray rabbits. Abbé Gillet, a local priest, considered the trait very fancy and started planning crosses to produce rabbits with this soft hair touching phenotype with guard hair that was no longer than the undercoat."
Mapping: Castle and Nachtsheim (1933) showed that r1 rex is linked to r2 rex (OMIA 002005-9986) with a recombination frequency of 10-12%. These same authors showed that the third type of rex in rabbits, r3 (OMIA 002006-9986), segregates independently of r1 and r2.
Molecular basis: Diribarne et al (2011) showed that the r1 rex hair coat phenotype in rabbits is due to a single nucleotide deletion in exon 9 of the LIPH gene.

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.
