Cross-species summary: or pheomelanin dilution, pigment intensity

Molecular basis: Weich et al. (2020) " identified a 6 kb copy number variant (CNV) 152 kb upstream of KITLG . . . [showing] a significant association between an increased copy number with the dark-red coat color [pheomelanin pigment intensity] in NSDTR". The authors also reported that the same CNV is " significantly associated with coat color variation in both eumelanin and pheomelanin-based Poodles . . . and across other breeds. Moreover, the copy number correlated with pigment intensity along the hair shaft in both pheomelanin and eumelanin coats."

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.
