OMIA 001737-9685 : Coat colour, white spotting, KIT-related in Felis catus

In other species: dog , ass , Arabian camel , cattle , goat

Possibly relevant human trait(s) and/or gene(s) (MIM number): 172800 (trait)

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Co-Dominant

Considered a defect: no

Key variant known: yes

Year key variant first reported: 2014

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.

Mapping: Cooper et al. (2006) reported that this locus maps near to KIT on FCA B1.

Molecular basis: David et al. (2014) reported the causal mutation of white spotting to be an insertion of an entire feline endogenous retrovirus (FERV1) into intron 1 of the KIT gene.

Frischknecht et al. (2015) confirmed this causal mutation.

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.
