Two faulty genes: The patient has mild anemia. In addition to history retrieve and physical examination, diagnosis of these disorders requires laboratory information. Severe anemia can damage organs and lead to death. Thalassemia Thalassemia is a common term for a group of inheritable, genetic diseases characterized by reduced levels of Hemoglobin, low RBCs production and anemia. If a person received an alpha thalassemia trait from her mother and the normal alpha parts from her father, she would have alpha thalassemia trait (also called alpha thalassemia minor). Beta Thalassemia can be defined by type: thalassemia major, intermedia, and minor, by genotype, or by TDT or non-TDT. This is especially important for those who receive transfusions, as they have a higher risk of contracting hepatitis A or B. Patients with thalassemia major will need between eight and twelve transfusions a year. The first type has one alpha gene missing on each chromosome (α-/α-) and is called as the trans form of alpha thalassemia trait.

Three faulty genes: The patient has hemoglobin H disease, a type of chronic anemia. β-Thalassemia and HbE, each, is a syndrome resulted from quantitative and qualitative defects of β-globin chain, respectively. This is now less common, because removing the spleen can lead to other complications. Some people find out about their thalassemia because they have relatives with a similar condition. Most children with moderate to severe thalassemia receive a diagnosis by the time they are 2 years old. An enlarged spleen can become overactive. Removing the spleen leads to a higher chance of infection, and regular transfusions increase the risk of contracting a blood-borne disease. In Thalassemia one of these chains is defective and depending upon the type of the protein chain involved it can be divided into two major types, Alpha and Beta Thalassemia. A fetus with four mutated genes cannot produce normal hemoglobin and is unlikely to survive, even with blood transfusions. The cells accumulate in the spleen, making it grow.
