Beta thalassemia genes are reported throughout the world, although more frequently in Mediterranean, African, and Southeast Asian populations. Symptoms of beta thalassemia occur when not enough oxygen gets to various parts of the body due to low levels of hemoglobin.

Beta-thalassemia also known as Cooley’s anemia. Beta-thalassemia happens when the body is unable to make an important blood protein called beta globin. Beta-thalassemia is caused by abnormalities in the beta-globin gene, located on chromosome 11. It is not a sex-linked genetic trait. Worldwide, beta thalassemia is affecting thousands of infants each year.

Alpha thalassemia occurs when one or much of the four alpha string genes fails to operate.

Thalassemia is a hard topic to explain, since the circumstance is not an unmarried disorder, but a group of defects with related clinical effects. Alpha string protein output, for pragmatic purposes, is equally divided among the four genes. Loss of two genes (two-gene omission alpha thalassemia) produces a circumstance with tiny crimson blood cells, and at most a balmy anemia. People with this circumstance feel and look natural. The circumstance can be detected by regular blood examination, however. The carrier country in alpha thalassemia normally refers to an individual who “carries” simply one irregular alpha-chain gene.

Autoimmune hemolytic anemia is more likely to occur in middle-aged and older individuals.

Autoimmune hemolytic anemia is a serious, life threatening disease. About half of the time, the cause of autoimmune hemolytic anemia cannot be determined. There are two main types of autoimmune hemolytic anemia: warm antibody hemolytic anemia and cold antibody hemolytic anemia. Autoimmune hemolytic anemia can also be caused by or occur with another disease, such as systemic lupus erythematosus, and rarely it follows the use of certain drugs, such as penicillin. In the warm antibody type, the autoantibodies attach to and destroy red blood cells at temperatures equal to or in excess of normal body temperature. In the cold antibody type, the autoantibodies become most active and attack red blood cells only at temperatures well below normal body temperature.
