OMIA 001322-93934 : Feather colour, roux in Coturnix japonica

Mendelian trait/disorder: yes

Mode of inheritance: Sex-linked

Considered a defect: no

Key variant known: yes

Year key variant first reported: 2007

Species-specific symbol: r

Molecular basis: Nadeau et al. (2007) showed that this plumage mutant corresponds to a SNP (giving rise to Phe282Ser) in the gene for TYRP1 - orthologous to the classic brown coat-colour locus in mammals.

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.
