Many of the mutations were gross deletions of exons 1-3 or exons 1-4.Īl-Herz W, Nanda A. Mutations in the DCLRE1C gene, which encodes ARTEMIS, have been described in a number of patients. A novel homozygous frameshift mutation in IL7R (c.562delC) was indentified in the proband with both parents being Taiwanese aborigines who were delineated as carriers, none of whom had Omenn syndrome. Accordingly, Omenn syndrome is best viewed, not as a specific form of SCID, but rather as an aberrant inflammatory condition that can be associated with multiple genetic abnormalities, which can significantly impair (but not abolish) T-cell development in the thymus. Thus, Omenn syndrome is a distinct inflammatory process that can be associated with genetically diverse, leaky SCIDS. However, Omenn syndrome is now known to occur in other leaky SCIDs with mutations in the RNA component of mitochondrial RNA processing endoribonuclease, adenosine deaminase, interleukin 2 (IL-2) receptor gamma, interleukin 7 (IL-7) receptor alpha, the nuclease ARTEMIS, and DNA ligase 4.
