Cross-species summary: FN acknowledges invaluable feedback from Cord Drögemüller that has led to the name of this phene being changed from "Coat colour, dilution" to "Coat colour, dilution, PMEL-related".

Molecular basis: Gutiérrez-Gil et al. (2007): c.64G>A

Jolly et al. (2008): c.50_52delTTC

Laible et al. (2021): "To better adapt dairy cattle to rapidly warming climates, we aimed to lighten their coat color by genome editing. ... Using gRNA/Cas9-mediated editing, we introduced a three bp deletion in the pre-melanosomal protein 17 gene (PMEL) proposed as causative variant for the semi-dominant color dilution phenotype observed in Galloway and Highland cattle. [Holstein Friesian] calves generated from cells with homozygous edits revealed a strong color dilution effect. ... This ... verified the causative nature of the PMEL mutation for diluting the black coat color in cattle." This study involves genetically modified organisms (GMO).

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.
