Haemoglobinopathy is a kind of genetic defect that results in abnormal structure of one of the globin chains of thehemoglobinmolecule. Hemoglobinopathies are inherited single-gene disorders; in most cases, they are inherited as autosomal co-dominant traits. Common hemoglobinopathies include sickle-cell disease. It is estimated that 7% of world's population (420 million) are carriers, with 60% of total and 70% pathological being in Africa.
Haemoglobin Functions :Transport of oxygen from the lungs to the tissues. This is due to the peculiar cooperation of the globin chains that allows the molecule to take in more oxygen where there is increased oxygen and to release oxygen in low concentration of oxygen.Transport of carbondioxide: from the tissue to the lungs.the end product of tissue metabolism is acidic which increases the hydrogen ion in solution. the hydrogen ion combines with bicarbonates to produce.
Symptoms and signs: Blood tests (Findings).
Statistics: Germany has been an immigration country since the early 1950s. In December 2007, 6.7 million non-German citizens lived in the country. However, the total number of citizens with a migration background is 15-20 million, about 9 million of whom come from countries where sickle cell disease and thalassaemias are frequent. In a country with 82 million inhabitants health authorities are not worried by the presence of probably 1000-1500 sickle cell and 450 transfusion-dependent thalassaemia patients.
