Severe combined immunodeficiency  (SCID ) results from genetic mutations  (changes in genetic material that can be passed on to children) that result in very small numbers of T cells  or B cells  (types of cells required for a normally functioning immune system). Because mutations in any 1 of at least 13 different genes can lead to SCID, there are several genetic types of SCID. The most common form is X-linked, which means that the gene is passed from mothers to their sons.
