Table 2.

Representation of males and females defined as G6PD deficient, assuming different thresholds for deficiency. The prevalence of G6PD deficiency is expressed in terms of hemizygous males with a G6PD-deficient allele. The numbers are calculated for a population of 10,000 with equal male and female distribution

For each prevalence, the total number (No.) of males (M), females (F), and the sum of the two (T) that have less than the threshold G6PD activity levels are given.

The relative proportions of the two genders from the total number of deficient (% def.) as well as the proportion (% pop.) of all males, all females, and the total population are also given.
