OMIA 002134-9913 : Abortion due to haplotype AH2 in Bos taurus
Guarini et al. (2019) reported the frequency of the AH2 haplotype in Canadian Ayrshires was less than 1% from 1997 to 2010 after which it rose to be around 11.2% in 2014 (estimated from their Figure 2).Breed: Ayrshire. 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.
