Median predicted allele frequency for G6PD deficiency map in 2010 globally

Download as: PDF PNG

This map shows the predicted allele frequency for G6PD deficiency within malaria endemic countries

Estimates were made based on data from community surveys which fed into a geostatistical model configured to give gene frequency estimates for populations on a spatial scale and adapted to reflect the X-linked inheritance of the G6PD gene. The model output a range of estimates (a posterior distribution) at each location (~5x5km) and the median estimate is shown on the above map. The interquartile range of estimates at eahc location is shown in the map below as a measure of uncertainty in the median predictions displayed above.
