Fava and colleagues compared LRRK2 polymorphisms between Leprosy patient families affected and free from type-1 reactions, and concluded that the majority of GWAS reported LRRK2 polymorphisms were actually associated with T1R susceptibility within Leprosy, rather than Leprosy susceptibility per se (Fava et al., 2016). The gene discussed is LRRK2; the disease is leprosy.
