1. THALASSAEMIA: Thalassaemia are inherited blood disorders which cause the body to make fewer healthy red blood cells and less haemoglobin (an iron-rich protein in red blood cells). The two major types of thalassaemia are alpha- and beta thalassaemia. Haemoglobin in red blood cells has two kinds of protein chains: alpha globin and beta globin. If the body doesn't make enough of these protein chains, red blood cells don't form properly and can't carry enough oxygen.
2. APLASTIC ANAEMIA: Aplastic anaemia is a blood disorder in which the body's bone marrow doesn't make enough new blood cells. Damage to the bone marrow's stem cells causes aplastic anaemia. In more than half of people who have aplastic anaemia, the cause of the disorder is unknown.

SICKLE CELL ANAEMIA: Sickle cell anaemia is a serious disease in which the body makes sickle-shaped ("C"-shaped) red blood cells. Normal red blood cells are disk-shaped and move easily through your blood vessels. Sickle cells contain abnormal haemoglobin that causes the cells to have a sickle shape, which don’t move easily through the blood vessels – they are stiff and sticky and tend to form clumps and get stuck in the blood vessels. Sickle cell anaemia is an inherited, lifelong disease.
5. PERNICIOUS ANAEMIA: Pernicious anaemia is a condition in which the body can't make enough healthy red blood cells because it doesn't have enough vitamin B12 (a nutrient found in certain foods). People who have pernicious anaemia can't absorb enough vitamin B12 due to a lack of intrinsic factor (a protein made in the stomach).
6.FANCONI ANAEMIA: Fanconi anaemia, or FA, is a rare, inherited blood disorder that leads to bone marrow failure. FA is a type of aplastic anaemia that prevents your bone marrow from making enough new blood cells for your body to work normally. FA can also cause your bone marrow to make many abnormal blood cells. This can lead to serious health problems, such as
