Neonatal clinicians should understand the screening and diagnostic approach to SCID along with the initial management approaches for these extremely high-risk patients. Once a definitive diagnosis of SCID has been established, treatment frequently involves bone marrow or stem cell transplantation however, enzyme replacement and gene therapy are also becoming options in those with SCID due to adenosine deaminase deficiency and other forms of SCID. Severe combined immunodeficiency ( SCID ), also known as Swiss-type agammaglobulinemia, is a rare genetic disorder characterized by the disturbed development of functional T cells and B cells caused by numerous genetic mutations that result in differing clinical presentations. Newborn screening for SCID is effective and allows for early implementation of lifesaving supportive measures, including protective isolation, initiation of prophylactic antimicrobials, caution with blood product transfusions, and avoidance of live vaccinations. Severe combined immunodeficiency (SCID) is one of the most severe forms of inborn errors of immunity (IEI), affecting both cellular and humoral immunity. Severe combined immunodeficiency (SCID) is the most noteworthy of these conditions, leading to considerable early morbidity and often death by the age of 1 year if left untreated. Combined immunodeficiencies can result, because B cells and natural killer cells rely on successful interactions with T cells to ensure their proper performance and survival. SCID, or severe combined immunodeficiency, is a set of genetic disorders that results in a lack of an immune system. Severe combined immunodeficiency (SCID), also known as Swiss-type agammaglobulinemia, is a rare genetic disorder characterized by the disturbed development of functional T cells and B cells caused by numerous genetic mutations that result in differing clinical presentations. The poor B and T cell development results in lymphopenia (less than 1,000. Healthy term newborns have baseline immune immaturity, increasing their risk of infections, but significant immunologic consequences can occur, because of abnormal T-cell maturation. This fatal disease was first described in the horse by McGuire and Poppie in 1973. The most severe is severe combined immune deficiency (SCID), where both the disease-fighting immune system T-cells and B-cells are absent or broken. The NBS Program screens for SCID by measurement of T-cell Receptor Excision Circles (TRECs). Because the human immune system is so complex, there are many possible genetic mutations that can result in severe congenital immune deficiency.

It is considered to be the most serious PIDD. a screen-positive result for severe combined immunodeficiency (SCID). The proper development and function of T cells is imperative in the creation of adequate cell-mediated and humoral immunity. Severe combined immunodeficiency (SCID) is an inherited primary immunodeficiency disease (PIDD) that typically presents in infancy results in profound immune deficiency condition resulting in a weak immune system that is unable to fight off even mild infections.
