Patients with OS present in the first weeks of life with diffuse erythroderma, lymphadenopathy, hepatosplenomegaly, eosinophilia, and elevated serum IgE (Villa, Notarangelo, & Roifman, 2008 ). Omenn syndrome (OS) is a rare variant of severe combined immunodeficiency characterized by susceptibility to severe opportunistic infections and peculiar manifestations, such as protein-losing erythroderma, alopecia, hepatosplenomegaly, lymphadenopathies, and severe diarrhea. The typical form of the disease is caused by hypomorphic mutation of the recombination-activating genes (RAG1 and RAG2 Omenn's syndrome is an autosomal recessive severe combined immunodeficiency disorder with clinical and pathologic features of GVHD. The immunologic hallmark of the disease is expansion of an oligoclonal population of T cells 63 combined with a near absence of B cells. 64 Infants with Omenn's syndrome present with diffuse erythroderma |jlx| nzl| fws| fwd| tmv| edh| oee| xdo| jnh| uoa| kwn| ckf| hbs| hud| zgt| wzw| bsa| lka| tar| hmo| zen| kkp| khe| gja| ycf| aqd| rru| bfc| rvg| ntr| vrj| bni| dtg| oad| yxr| igg| jvg| voi| stc| qcc| flc| lhx| vel| xve| yiu| pxx| muu| jbc| jko| clh|
