FMF mutations confer resistance to Yersinia pestis — heterozygote advantage confirmed

Familial Mediterranean Fever

Summary

Park et al. (2020, Nat Immunol) demonstrated that FMF-associated pyrin mutations provide enhanced resistance to Yersinia pestis virulence factors. This explains the remarkably high carrier frequencies (1 in 3.5 to 1 in 5) in Mediterranean populations through positive evolutionary selection.
