From: A nonsense mutation in the COL7A1 gene causes epidermolysis bullosa in Vorderwald cattle
Homozygosity mapping on bovine chromosome 22 in five calves with epidermolysis bullosa. Light blue, grey and dark blue, respectively, represent homozygous, heterozygous and alternate homozygous genotypes in five calves with epidermolysis bullosa from Vorderwald (VWD) and Rotes Höhenvieh (RHV) cattle. The orange frames indicate common segments of extended homozygosity within breeds. The green bar represents a 8.72 Mb segment of extended homozygosity that was shared among the diseased calves from both breeds. The red triangle represents the position of the rs876174537 T-allele (red triangle) in the COL7A1 gene
