OMIA 000214-9913 : Coat colour, white spotting in Bos taurus

In other species: domestic cat , dog , horse , water buffalo , domestic guinea pig

Possibly relevant human trait(s) and/or gene(s)s (MIM numbers): 193510 , 103500

Mendelian trait/disorder: no

Mode of inheritance: Multifactorial

Considered a defect: no

Key variant known: yes

Year key variant first reported: 2012

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"), not by failure in the biochemical reactions required for pigment synthesis.

Molecular basis: Fontanesi et al. (2012) reported a strong association between an intronic MITF variant and spotted vs non-spotted Italian Holstein and Italian Simmental cattle, explaining that "Variability in the MITF gene clearly explained the differences between spotted and non-spotted phenotypes but, at the same time, it is evident that this gene is not the only genetic factor determining piebaldism in Italian Holstein and Italian Simmental cattle breeds."

Hofstetter et al. (2019) "hypothesize[d] that rs722765315 [variant g.31908435G>A in MITF] represents the most likely causative variant for the white-spotting phenotype observed in Brown Swiss cattle. Presence of the mutant allele in a heterozygous or homozygous state supports a dominant mode of inheritance with incomplete penetrance and results in a variable extent of coat colour depigmentation."

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.
