Buruli ulcer, the third most common mycobacterial disease worldwide, is caused by Mycobacterium ulcerans and characterized by devastating necrotizing skin lesions. Susceptibility to Buruli ulcer is thought to depend on host genetics, but very few genetic studies have been performed. The identification of a microdeletion on chromosome 8 in a familial form of severe Buruli ulcer suggested a monogenic basis of susceptibility. The role of common host genetic variants in Buruli ulcer development has been investigated in only three candidate-gene studies targeting genes involved in mycobacterial diseases. A recent genome-wide association study suggested a probable role for long non-coding RNAs and strengthened the contribution of autophagy as a major defense mechanism against mycobacteria. In this review, we summarize the history, epidemiological and clinical aspects of Buruli ulcer, focusing particularly on genetic findings relating to susceptibility to this disease. Finally, we discuss exciting new genetic avenues arising, in particular, from studies of mouse models, and the need for different disciplines to work together, to benefit from the extensive work on other mycobacterial diseases, mostly tuberculosis and leprosy. We are convinced that such pooling of effort will lead to the development of efficient novel strategies for combatting Buruli ulcer.
