Distribution of abnormal hemoglobins and glucose-6-phosphate dehydrogenase variants in 1200 school children of Bahia, Brazil

School children from Bahia, Brazil were studied for hemoglobin and glucose‐6‐phosphate dehydrogenase electrophoretic variants. Eighty‐nine heterozygotes Hb AS and 41 Hb AC were identified out of 1200 children. In a subsample of 369 male children there were 38 Gd A−, 38 Gd A, and six Gd Med. An example of Gd MG was identified and evidence is added to the suggestion that this allele is not rare in Brazil.
