OMIA:001737-9925 : Coat colour, white spotting, KIT-related in Capra hircus (goat) |
In other species: dog , domestic cat , ass (donkey) , Arabian camel , taurine cattle
Categories: Pigmentation phene
Possibly relevant human trait(s) and/or gene(s)s (MIM numbers): 172800 (trait) , 164920 (gene)
Links to MONDO diseases: No links.
Mendelian trait/disorder: yes
Considered a defect: no
Key variant known: yes
Year key variant first reported: 2019
Cross-species summary: Variable degree of white spotting ranging from tiny white spots up to completely white animals. The absence of pigment is caused by the absence of skin melanocytes ("leucism, leucistic"), not by failure in the biochemical reactions required for pigment synthesis.
Molecular basis: Henkel et al. (2019) reported two "CNVs were located in the 3’-flanking region of KIT and associated with a completely white coat color phenotype in Pak Angora goats [see OMIA 000209-9925] and a white-spotted coat color phenotype in Barbari goats [this OMIA entry], respectively".
Genetic engineering:
Unknown
Have human generated variants been created, e.g. through genetic engineering and gene editing
Breeds:
Barbari (Goat) (VBO_0000728),
Pak Angora, Pakistan (Goat) (VBO_0009787).

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.
