TY - JOUR T1 - SEvere combined immunodeficiency AU - Punnoose AR, Lynm C, Golub RM Y1 - 2013/01/02 N1 - 10.1001/jama.2012.6226 JO - JAMA SP - 98 EP - 98 VL - 309 IS - 1 N2 - 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. SN - 0098-7484 M3 - doi: 10.1001/jama.2012.6226 UR - http://dx.doi.org/10.1001/jama.2012.6226 ER -
