[Patterns in the distribution of GPD- alleles in Azerbaijan. I. Incidence and polymorphism of glucose-6-phosphate dehydrogenase deficiency in the Shekii region of the Azerbaijan SSR].

Through examination of G6PD deficiency among 939 pupils of Shekii district of Azerbaijan 52 hemi-, 10 homo- and 58 heterozygous carriers of defect were found. Relatives of probands--inhabitants of 3 settlements in the Shekii district-- were examined on G6PD deficiency too. Average hemizygote frequency is 11.11%, heterozygotes frequency is 12.9%. The cases of disaccordance between phenotype and genotype in female carriers of Gd- are analysed using pedigree data.
