Molecular characterization of Glucose-6-phosphate dehydrogenase (G6PD) variants in the Cuban population . Rev Cubana Hematol Inmunol Hemoter [online]. 2008, vol.24, n.2, pp. 0-0. ISSN 1561-2996.

G6PD deficiency is the most common erythroenzymopathy in the world. The molecular study of 50 variants of G6PD with diminished enzymatic activity and/or carriers of electrophoretic variants was conducted. Of 38 patients with rapid variants, 33 were G6PD A- 376/202; 3 were G6PD A- 376/968 (class 3) and 2 were rare variants. Seven deficient variants with normal electrophoretic mobility were classified as G6PD Santamaría376/542 (class 2). Of the 4 cases with slow variants, one was carrier of G6PD Sao Borja337 (class 4); other 2 were rare electrophoretic variants with normal activity. In a patient with CNSHA it was not possible to determine the molecular variant (class 1). The most frequent variant in our population was G6PD A- 376/202 that is a marker for the black race. No patient with Mediterranean variety was found. This was the first molecular study of G6PD conducted in Cuba.
