OMIA 001362-9823 : Coat colour, blond in Sus scrofa

In other species: meadow voles

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Dominant

Considered a defect: unknown

Key variant known: yes

Year key variant first reported: 2015

Molecular basis: Using the candidate gene approach, Wu et al. (2016; first published online in 2015) provided strong evidence that a 6bp deletion in TYRP1 (g.17599_17604del; p.M495_G496del) is the cause of the blond coat colour in Liangshan pigs.

Breed: Liangshan.

Associated gene:

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.
