Cross-species summary: The name of this phene was changed from "Coat colour, white spotting, PAX3-related" to "Auditory-pigmentary syndrome, PAX3-related" on 01-Mar-2024.
The phene includes altered pigmentation of the eyes and/or skin together with a predisposition for unilateral or bilateral sensineural deafness. Affected animals often have blue eyes or eyes with different colors (heterochromia iridis). Skin pigmentation may include variable degrees of white spotting ranging from tiny white spots up to completely white animals. The absence of pigment is caused by the absence of melanocytes ("leucism"), not by a failure in the biochemical reactions required for pigment synthesis. The increased risk for deafness is the consequence of lacking melanocytes in the stria vascularis of the inner ear.

Species-specific name: Dominant blue eyes (DBE)

Genetic engineering: Unknown
Have human generated variants been created, e.g. through genetic engineering and gene editing

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.
