THALASSEMIA

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Clinical signs of disease vary, depending on the class of ____ involved, as well as gene zygosity.
A
Altered stability
B
globin chain
C
Solubility
D
Altered function
Explanation: 

Detailed explanation-1: -Thalassemia can be defined as a condition in which a reduced rate of synthesis of one or more of the globin chains leads to imbalanced globin-chain synthesis, defective hemoglobin production, and damage to the red cells or their precursors from the effects of the globin subunits that are produced in relative excess.

Detailed explanation-2: -Thalassemia is a genetic disorder in which there is decreased production of one of the globin chains found in hemoglobin. This oxygen-transporting molecule in blood normally contains four globin chains, two alpha (a) and two non-a, each with its own heme group (made of an iron atom bound in protoporphyrin ring).
