Glucose-6-phosphate dehydrogenase deficiency in the Greek population of Cape Town.

A sample of 250 unrelated members of the Greek community of Cape Town was studied in order to establish the prevalence of glucose-6-phosphate dehydrogenase (G-6-PD) deficiency in the community. A gene frequency of 0,067 in males and a prevalence of 6,7% are estimated for this group. It is recommended that persons with G-6-PD deficiency should have access to a list of medicinal agents which have the potential for precipitating acute haemolytic crises and that they should wear Medic-Alert discs bearing information concerning the disorder.
