Write answer in between .Q:A 6-year-old child presents for evaluation of a medical condition associated with recurrent infections. After reviewing all of the medical history, gene therapy is offered to treat a deficiency in adenosine deaminase ADA. ADA deficiency is the most common autosomal recessive mutation in which of the following diseases?? A: DiGeorge Syndrome, B: Severe Combined Immunodeficiency, C: Hyper-IgM Syndrome, D: Wiskott-Aldrich Syndrome, E: Brutons Agammaglobulinemia,  <response>: This is a question asking about which disease is most commonly associated with autosomal recessive mutations in the adenosine deaminase ADA gene. The key information in the stem is that it is an autosomal recessive mutation leading to recurrent infections, and specifically a deficiency in ADA. Of the choices given, Severe Combined Immunodeficiency SCID is caused by autosomal recessive mutations in several genes, including ADA. ADA deficiency is the most common cause of SCID. DiGeorge Syndrome is caused by a deletion in chromosome 22, not an autosomal recessive mutation. Hyper-IgM Syndrome is X-linked. Wiskott-Aldrich Syndrome is X-linked. Brutons Agammaglobulinemia is X-linked.Therefore, the correct answer should be Severe Combined Immunodeficiency.B: Severe Combined Immunodeficiency
