Thalassemia: Causes, Symptoms, Diagnosis, and Treatment Guidelines for the Clinical Care of Patients with Thalassemia in Canada. 16.5 β THALASSEMIA MINOR 16.5.1 Definition This is an inherited defect in haemoglobin synthesis where there is a decrease in globin chain synthesis. Several forms of hemoglobin E/β-thalassemia, S/β-thalassemia, and hemoglobin C/β-thalassemia are common, yet these forms need molecular analysis as they have unique characteristics and management peculiarities 5. Intermediate forms of thalassemia can cause mild to moderate anemia and may be associated with other health problems such as slowed growth, delayed puberty, bone problems and/or an . Thalassemia intermedia may result from a variety of molecular processes, but its milder clinical presentation is usually due to a less marked imbalance of the α:β globin chain ratio. But more severe forms might require regular blood transfusions. Satu dari orang tua menderita thalasemia trait/bawaan maka kemungkinan 50% sehat dan 50% thalasemia trait. The symptoms of thalassemia major generally appear before a child's second birthday. The diagnosis is usually suspected in children or adults with an unexplained mild microcytic hypochromic anemia .
