Aplastic anemia occurs because of damage to stem cells inside bone marrow, which is the sponge-like tissue within your bones. Many diseases and conditions can damage the stem cells in bone marrow. As a result, the bone marrow makes fewer red blood cells, white blood cells, and platelets.

Fanconi anemia is an inherited disease caused by mutations in certain genes, known as FA genes. These genes provide instructions to help the body repair certain types of DNA damage. The cells of healthy people often repair DNA damage, but cells affected by Fanconi anemia cannot make these repairs. In people who have Fanconi anemia, certain cells may die or stop working properly.

Red blood cells develop in the bone marrow, which is the sponge-like tissue inside your bones. Your body normally destroys old or faulty red blood cells in the spleen or other parts of your body through a process called hemolysis. Hemolytic anemia occurs when you have a low number of red blood cells due to too much hemolysis in the body.
