Clinical Information
  • Group of rare congenital disorders characterized by impairment of both humoral and cell-mediated immunity, leukopenia, and low or absent antibody levels; it is inherited as an x-linked or autosomal recessive defect; about half of the patients with autosomal recessive scid are deficient in the enzyme adenosine deaminase
  • X-linked or autosomal recessive disorder characterized by defects of both humoral and cell mediated immunity, resulting in low or absent antibody levels, leukopenia, marked susceptibility to infections, and early death
