There is no central record of how many babies are diagnosed with SCID in the United States each year, but the best estimate is somewhere around So, SCID is a rare condition.

On the other hand, researchers have no clear idea of how many babies are not diagnosed and die of SCID-related infections each year. The actual number of cases could be higher. If a baby exhibits any of the following persistent symptoms within the first year of life, he or she should be evaluated for SCID or other types of immune deficiency syndromes:.

This gene creates a key part of a receptor on the surface of a lymphocyte which, when activated by chemical messengers called cytokines, transmits information that directs lymphocytes to mature, proliferate and mobilize to fight infection.

The defective part of the lymphocyte receptor is called the "common" gamma chain, because it is a common component of lymphocyte receptors for several types of cytokines, including the interleukin-2 IL-2 receptor. Thus, it is a critical component for mobilizing the body's defenses against infection.

Because females have two X chromosomes, if they have a mutation that disrupts the IL2RG gene on one X chromosome, they still have a spare normal gene on the other X chromosome that can compensate for the mutation. Thus, they have normal immune systems. A male with a defect in his only IL2RG gene produces immune cells that are missing the? Because the receptors cannot respond to stimulation, immune dysfunction and SCID sets in.

Therefore, the overall incidence of SCID is higher in males than in females. It is caused by a mutation in the gene that encodes a protein called adenosine deaminase ADA.

This enzyme also breaks down toxic metabolites that otherwise accumulate to harmful levels that kill lymphocytes. People afflicted with this disease often have to take antibiotics and supplemental infusions of antibodies to protect themselves from serious infections. They can also receive adenosine deaminase injections given once or twice a week.

Early diagnosis of SCID is rare because doctors do not routinely count each type of white blood cell in newborns. As a result, the average age at which babies are diagnosed with SCID is just over six months, usually because of recurrent infections see below and failure to thrive.
