OMIA 000201-9793 : Coat colour, agouti in Equus asinus |
From a survey of 283 donkeys, Yu et al. (2020) reported "Donkeys homozygous for the ASIP [c.349]T‐allele all have light points, which are missing in all homozygous C‐allele genotype at c.349T>C (CC) animals . . . However, 27.8% of the NLP [no light points] donkeys are heterozygous, which has not been found previously. . . . The variable phenotypes of ASIP heterozygotes and of ASIP TT homozygotes indicate the involvement of one or more other genes that so far have not been identified."

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.
