OMIA:001263-9796 : Coat colour, champagne in Equus caballus (horse) |
Categories: Pigmentation phene
Links to possible relevant human trait(s) and/or gene(s) in OMIM: 606561 (gene)
Mendelian trait/disorder: yes
Mode of inheritance: Autosomal dominant
Disease-related: no
Key variant known: yes
Year key variant first reported: 2008
Mapping: From a genome scan with 102 microsatellites, Cook et al. (2008) mapped this trait to a 6 cM region on chromosome ECA14.
Molecular basis: Sequencing of three candidate genes in the mapped region (see Mapping section above) enabled Cook et al. (2008) to identify a causal mutation as the substitution of "C to a G at base 76 of exon 2 (c.188C>G)" of the SLC36A1 gene, resulting in the amino-acid substitution T63R.
Breeds:
American Cream Draft (Horse) (VBO_0017088),
American Miniature Horse (Horse) (VBO_0000896),
American Paint (Horse) (VBO_0000897),
American Saddle Horse (Horse) (VBO_0000898),
Appaloosa (Horse) (VBO_0000904),
Missouri Fox Trotting Horse (Horse) (VBO_0017148),
Quarter Horse (Horse) (VBO_0001057),
Tennessee Walking Horse (Horse) (VBO_0001081).

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.
