A very large multi-country genetic association study with over 11,000 severe malaria cases and 17,000 population controls found no overall protective effect of the G6PD + 202T allele (the most common mutation in sub-Saharan Africa causing G6PD deficiency), under an additive model (Malaria Genomic Epidemiology Network, 2014). Here, G6PD is linked to G6PD deficiency.
