G6PD and G6PD deficiency: Finally, we identified a couple of resources specific to G6PD deficiency: (1) the G6PD deficiency database created by Dr Andrew Martin's group at University College London (http://www.bioinf.org.uk/g6pd/index.html) provides information on mutations leading to deficiency but no geographical information is provided; and (2) G6PD MutDB (http://bminfor.tongji.edu.cn/mutdb/) links mutations to deficiency phenotypes [Zhao et al., 2010] and while information on ethnic backgrounds is included, geographical location is not.
