Following an abnormal newborn screen, blood testing to measure the number of the T, B and NK cells is needed to see if the newborn actually has SCID. The immunologist will also test the function of the T cells with another blood study. If the number of T cells is very low, genetic testing will be recommended to determine the type of SCID your child has so that this information can guide treatment recommendations.
Hospital stays will be required for testing, treatment, and, if needed, recovery time from infections. Long hospital stays can take their toll on families, but there are steps families can take to reduce the stress. From knowing what to expect to making the best use of time in the hospital, families can minimize the effects of daily life in the hospital. Following HSCT, the baby will undergo months of immune system monitoring to determine if the HSCT was successful. With HSCT, there can be a number of complications, and sometimes the HSCT needs to be repeated.
Because your baby may have little or no immune system, the most important thing to do right now is to keep your baby from getting sick. Even if the child has not yet been diagnosed, the safest course of action is to assume that they have an immune problem until proven otherwise. Illnesses that would normally not be a cause for concern can cause life-threatening complications in children born with SCID. Patients with an abnormal newborn screen are initially seen by the CHOP Immunology team to have their diagnosis confirmed. Once a diagnosis of SCID is confirmed, the referral is made to the CHOP BMT team.
Tips and expectations for hospital stays
A lack of T cells is essential to SCID diagnosis, but no or low T cells may also occur in other health conditions. Severe combined immunodeficiency (SCID) causes babies to be born with little or no immune system. This means common, usually mild infections can be fatal because their bodies don’t have a strong enough natural defense system. Secretary of Health and

At the SCID Foundation, our mission is to empower families affected by Severe Combined Immunodeficiency (SCID) through awareness, education, advocacy, and support. These are a few examples of the ways in which families deal with uncertainty in their SCID journey. Blood or blood products should be irradiated, leukocyte depleted, and negative for CMV before being administered to patients with confirmed or suspected SCID. Babies affected by SCID are not able to produce their own antibodies to fight infection. The missing antibodies are replaced by giving treatment with immunoglobulin.
You may feel worried or frustrated when doctors cannot guarantee that using conditioning will lead to a more successful transplant for your child than not using conditioning, or vice versa. Families often say that going through a treatment when there is a lot of uncertainty is one of the hardest parts of their child’s journey with SCID. Parents’ involvement in making a choice about using conditioning may vary.
Four other forms of SCID are due to variants in genes that code for four of the individual protein chains that make up CD3, another component of the T cell receptor complex. These SCID-causing gene variants result in deficiencies of CD3 delta, epsilon, gamma, or zeta chains. These deficiencies are inherited as autosomal recessive traits and account for less than 5% of individuals with SCID. If you live in the U.S., your baby will be screened for it when they’re born.
SCID is the result of an immune system so highly compromised that it is considered almost absent. The most common treatment for SCID is an allogeneic bone marrow transplant, which will introduce normal infection-fighting cells into your child’s body. Allogeneic transplants use stem cells from a relative or an unrelated donor from the National Marrow Donor Program.
The numbers of B cells and NK cells are normal, but the B cells don't work because of the lack of T cells. IL7R deficiency is inherited as an autosomal recessive trait, so both boys and girls can be affected. Severe combined immunodeficiency (SCID) is a group of rare, life-threatening diseases that cause a child to be born with very little or no immune system. As a result, the child’s body is unable to fight off infections and can become very sick from infections like chickenpox, pneumonia and meningitis and can die within the first year of life. The immediate priorities will be to provide an environment which protects from infection, to perform appropriate tests and assessments, and to start treatment for infection and other protective measures. Subsequently, possible treatments that can correct the defect will be discussed.
