(b) Adenosine deaminase (ADA) deficiency. It is associated with (SCID) severe combined immunodeficiency. ADA is very crucial for immune systems to function. The deficiency of ADA causes severe combined immune deficiency disease. The patient lacks functional T-lymphocyteo and fails to fight the infections pathogens.
Using the gene-therapy lymphocytes are extracted from the patient’s bone marrow and a normal functional gene for ADA is introduced into these lymphocytes with the help of the retro virus. The lymphocyctes of bone marrow contains the functional ADA gene and reactivate the patient’e immune system.
In some children, ADA deficiency can be treated bone marrow transplantation, in other it can be treatedby enzyme replacement therapy, in which functional ADA is given to the patient by injection.
