Thalassemia comes from the Greek word "Thalassa" which means: the sea.

Thalassemia is an inherited disorder of Blood. In this disorder, hemoglobin is not produced in an adequate amount. Types of hemoglobin are A, A2, F, H, Bart's, and Portland. These major forms of hemoglobin are further subclassified as alpha, beta, gamma, and delta globin chains.

What is alpha-thalassemia? 
      Alpha thalassemia is an autosomal recessive disorder caused by deletion of alpha globin genes on chromosome 16.

   Alpha Thalassemia is a rare blood disorder that  disrupts the body's production of hemoglobin. Hemoglobin is a protein that helps carry oxygen throughout the body. Alpha Thalassemia also reduces the red blood cell count in the body, which could possibly lead to Anemia. Anemia itself can lead to a host of additional symptoms and complications.

What is beta thalassemia?
    Beta thalassemia is a genetic disorder where there's a deficiency in production of the B-globin chains of hemoglobin, which is the oxygen-carrying protein in red blood cells - or RBCs for short.
