OMIA 000245-9615 : Curly coat in Canis lupus familiaris
In adjacent papers published online just three days apart, Bauer et al. (2019) and Salmela et al. (2019) independently reported a second likely causal variant (c.1266_1273delinsACA) in Curly Coated Retrievers, a breed with curly coats but which does not have the previously-known variant, c.451C>T.Prevalence: Bauer et al. (2019) "found that the [c.1266_1273delinsACA] variant was fixed in a cohort of 125 Curly Coated Retrievers and segregating in five of 14 additionally tested breeds with a curly or wavy coat".
Salmela et al. (2019): "The [c.1266_1273delinsACA] variant was also found at lower frequencies in five other breeds, including Lagotto Romagnolo, Bichon Frise, Spanish Water Dog, Chesapeake Bay Retriever and Irish Terrier." These authors also reported that "One curly-coated Lagotto carried neither of the two KRT71 variants", indicating that not all the likely causal variants have yet been discovered.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.
