OBJECTIVES: Identify and screen the G6PD Mediterranean mutation in favism patients by applying A Amplification Refractory Mutation System Polymerase Chain Reaction (ARMS-PCR).

PATIENTS AND METHODS: A total of 114 unrelated Egyptians patients were included in the present study; their ages ranged between (2-9) years with male to female ratio 4.5:1. G6PD activity was determined qualitatively from red cell hemolysate during attack. The G6PD Mediterranean mutation in patients has been identified by ARMS-PCR.

RESULTS: G6PD deficiency was detected in 87.7%, (n=100). The frequency of G6PD Mediterranean mutation was (94.7%), (n=108). The association between G6PD deficiency and Mediterranean mutation was a highly significant.

CONCLUSIONS: Glucose-6-phosphate dehydrogenase Mediterranean mutation is one of the most common mutations causing G6PD deficiency among Egyptian children with favism.
