In this paper are brought the results obtained in two Parisian hospitals during a survey of abnormal hemoglobins in 540 immigrant workers coming from Africa, mostly from Mali, Mauritania and Senegal. All the subjects investigated were male and between 20 and 40 years old. The studies were performed following internationally standardized technics. The most frequent abnormalities were: Hb S found in 16.3%, Hb C (6.6%), alpha-thalassemia trait (3.1%) and beta-thalassemia trait (3.1%). Some rare abnormalities were also found: delta-chain variants, hereditary persistance of foetal hemoglobin, Hb Hope and Hb Grady. This work emphasizes the high frequency of the different hemoglobin disorders in this population. The easy diagnostic of electrophoretically detectable variants is compared to the more complex situation of thalassemia leading probably to an under estimation of the percentage.

UI MeSH Term Description Entries
D007501 Iron A metallic element with atomic symbol Fe, atomic number 26, and atomic weight 55.85. It is an essential constituent of HEMOGLOBINS; CYTOCHROMES; and IRON-BINDING PROTEINS. It plays a role in cellular redox reactions and in the transport of OXYGEN. Iron-56,Iron 56
D008297 Male Males
D004586 Electrophoresis An electrochemical process in which macromolecules or colloidal particles with a net electric charge migrate in a solution under the influence of an electric current. Electrophoreses
D004912 Erythrocytes Red blood cells. Mature erythrocytes are non-nucleated, biconcave disks containing HEMOGLOBIN whose function is to transport OXYGEN. Blood Cells, Red,Blood Corpuscles, Red,Red Blood Cells,Red Blood Corpuscles,Blood Cell, Red,Blood Corpuscle, Red,Erythrocyte,Red Blood Cell,Red Blood Corpuscle
D005319 Fetal Hemoglobin The major component of hemoglobin in the fetus. This HEMOGLOBIN has two alpha and two gamma polypeptide subunits in comparison to normal adult hemoglobin, which has two alpha and two beta polypeptide subunits. Fetal hemoglobin concentrations can be elevated (usually above 0.5%) in children and adults affected by LEUKEMIA and several types of ANEMIA. Hemoglobin F,Hemoglobin, Fetal
D005602 France A country in western Europe bordered by the Atlantic Ocean, the English Channel, the Mediterranean Sea, and the countries of Belgium, Germany, Italy, Spain, Switzerland, the principalities of Andorra and Monaco, and by the duchy of Luxembourg. Its capital is Paris. Corsica,Saint Pierre and Miquelon,Miquelon and Saint Pierre,Miquelon and St. Pierre,St. Pierre and Miquelon
D006443 Hemoglobin A2 An adult hemoglobin component normally present in hemolysates from human erythrocytes in concentrations of about 3%. The hemoglobin is composed of two alpha chains and two delta chains. The percentage of HbA2 varies in some hematologic disorders, but is about double in beta-thalassemia. A2, Hemoglobin
D006444 Hemoglobin C A commonly occurring abnormal hemoglobin in which lysine replaces a glutamic acid residue at the sixth position of the beta chains. It results in reduced plasticity of erythrocytes.
D006451 Hemoglobin, Sickle An abnormal hemoglobin resulting from the substitution of valine for glutamic acid at position 6 of the beta chain of the globin moiety. The heterozygous state results in sickle cell trait, the homozygous in sickle cell anemia. Hemoglobin S,Deoxygenated Sickle Hemoglobin,Deoxyhemoglobin S,Hemoglobin SS,Hemoglobin, Deoxygenated Sickle,SS, Hemoglobin,Sickle Hemoglobin,Sickle Hemoglobin, Deoxygenated
D006453 Hemoglobinopathies A group of inherited disorders characterized by structural alterations within the hemoglobin molecule. Hemoglobinopathy
