Cross-species summary: Junctional epidermolysis bullosa, Herlitz-type is a severe subtype of junctional epidermolysis bullosa (JEB) characterized by blisters and extensive erosions, localized to the skin and mucous membranes. [ Orphanet:79404 ]
Molecular basis: "2.4 kb deletion encompassing the first exon of the LAMC2 gene" (Murgiano et al., 2015)
Have human generated variants been created, e.g. through genetic engineering and gene editing
Hereford (Cattle) (VBO_0000232).

By default, variants are sorted chronologically by year of publication, to provide a historical perspective.

order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column
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.
