OMIA 001678-9913 : Epidermolysis bullosa, junctionalis, LAMC2-related in Bos taurus

In other species: horse , sheep

Possibly relevant human trait(s) and/or gene(s) (MIM number): 226700

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Recessive

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2015

Cross-species summary: Blisters in and around the mouth and on the limbs, leading in the latter case to separation of the hoof from the corium (dermis), resulting in inability to stand.

Molecular basis: "2.4 kb deletion encompassing the first exon of the LAMC2 gene" (Murgiano et al., 2015)

Breed: Hereford.

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.
