    Doberman hepatitis (DH) is associated with homozygous DLA-DRB1*00601/DQA1*00401/DQB1*01303 indicating a role for the immune system in the development of the disease. The dog leucocyte antigen (DLA) class II expression is controlled at the transcriptional level with proximal promoters. Differential expression of DLA class II molecules of antigen-presenting cells is reported to affect susceptibility to or protection from different immune-mediated diseases. The aim of this study was to evaluate, whether the variation in promoter areas of homozygous DLA-DRB1*00601/DQA1*00401/DQB1*01303 Dobermans could explain why some dogs become afflicted with DH and others do not. Our findings suggest that promoter variants are not associated as risk modifiers in homozygous DLA-DRB1*00601/DQA1*00401/DQB1*01303 Dobermans, but additional factors are needed. Nevertheless, our study indicates that the whole DLA block is associated to the disease. © 2011 John Wiley & Sons A/S.
