A new study showed that incidence and morbidity of many diseases and disorders correlate negatively with frequencies of Rh+ heterozygotes (i.e. the carriers of one copy of the gene for Rh positivity and one copy of the gene for Rh negativity) in the population of individual countries. At the same time, the disease burden associated with the same disorders correlated positively with frequency of Rh negative subjects in individual countries. Together with the observed worse health status and higher incidence of many disorders in Rh negative subjects published by the same research team last autumn, this result probably solved 80 years old enigma of coexistence of carriers of two variants of Rhesus gene in the same population.
