![]() ![]() Gene therapy is a newer treatment option that involves introducing healthy genes into the patient's cells to rectify the genetic defect. Stem cell transplantation is the most common treatment, and involves replacing the faulty immune system with healthy stem cells from a donor. Treatment of SCID typically involves a stem cell transplant or gene therapy. Genetic testing is utilized to determine the specific genetic defect causing SCID. SCID diagnostic criteria proposed by the Primary immune Deficiency Treatment Consortium (PIDTC) help to distinguish typical SCID from leaky SCID and Omenn syndrome (Table 1). Laboratory tests may include lymphocyte counts, enzyme assays, and immunophenotyping. Clinical indicators may include recurrent infections, failure to develop, and chronic diarrhea. The diagnosis of SCID is commonly established through a combination of clinical indicators, laboratory tests, and genetic testing. SCID is generally identified in infancy and, if left untreated, can be fatal. The transplanted cells provide healthy, functioning stem cells from a donor. Learn about the Transplant Program at St. Primary immunodeficiency disorders can be cured or managed with a stem cell transplant. It is caused by a genetic flaw that leads to a lack of both T and B lymphocytes. Patients with SCID and Wiskott-Aldrich syndrome are often treated with bone marrow transplants. Some clinical trials have shown positive outcomes for children, but this form of therapy is still being studied as there. Severe combined immunodeficiency (SCID) is a rare, inherited disorder of the immune system that impairs the body's ability to fight off infections. With treatment, most people with SCID can live a normal life. The prognosis for those with SCID is good if they receive treatment early. If a donor cannot be found, gene therapy may be used to fix the faulty gene and restore the immune system. This transplant replaces the flawed immune system with a healthy one. Treatment for SCID is typically a bone marrow transplant from a healthy donor. Other types of SCID are caused by mutations in other genes, such as RAG1 and RAG2, which are responsible for the recombination of DNA in B- and T-cells. Without ADA, the body cannot produce the proteins needed for the growth of B- and T-cells. The most common form of SCID is X-linked SCID, which is caused by a mutation in the gene that produces the enzyme adenosine deaminase (ADA). Without treatment, this condition can be fatal within the first year of life due to serious infections. It is characterized by a lack of both B-cell and T-cell function, leading to a drastically weakened immune system. Severe Combined Immunodeficiency (SCID) is an extremely rare, inherited disorder caused by a mutation in the genes responsible for making proteins that are essential for the development of a healthy immune system. ![]()
