Some reported LRLs/LDLs have been estimated from small sample sizes, [7,11,12] from populations with high G6PD deficiency prevalence, [8-10,13,15,16] and from mixtures of G6PD-normal and G6PD-deficient preterm and full-term neonates [8,15]. The gene discussed is G6PD; the disease is G6PD deficiency.
