Genetic modifiers of anemia in Plasmodium falciparum infection and sickle cell disease (SCD) are not fully known. Both conditions are associated with oxidative stress, hemolysis and anemia. CYB5R3 encodes cytochrome b5 reductase 3, which converts methemoglobin to hemoglobin through oxidation of NADH. CYB5R3c.350C>G , the most frequent recognized African-specific polymorphism, does not have known functional significance, but its high allele frequency (23% in African-Americans) suggests a selection advantage.
sickle cell disease
Management of fever is a key element of care for children with sickle cell disease (SCD). There exist few studies of current practices in managing fevers in SCD in low- and middle-income countries (LMICs) and malaria-endemic regions where SCD is prevalent.
