OMIA:001737-9685 : Coat colour, white spotting, KIT-related in Felis catus |
In other species: dog , ass , Arabian camel , cattle , goat
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
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.
Species-specific description: see also "OMIA 000214-9685 : Coat colour, white spotting in Felis catus"
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. David et al. (2014) identified in the same study that a 617bp insertion of a long terminal repeat (LTR) of the feline endogenous retrovirus (FERV1) is associated with domiant white - see OMIA 000209-9685 : Coat colour, dominant white in Felis catus’ for further detail.
Frischknecht et al. (2015) confirmed the causal mutation for white spotting.

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.
