Molecular basis: Zhan et al. (2012): "A single nucleotide polymorphism (MC1R: c.376A>G) in the MC1R gene was found to be highly correlated with pigment phenotype in the Gyrfalcon. Homozygous genotypes c.376GG and c.376AA were found to dominate the extreme white and dark plumage types respectively, and heterozygotes occurred mainly in intermediate phenotypes. However, some heterozygotes were associated with extreme phenotypes, indicating that melanism/albinism might also involve other loci."

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.
