| An inflammatory condition characterized by erythroderma, desquamation, alopecia, chronic diarrhea, failure to thrive, lymphadenopathy and hepatosplenomegaly associated with severe combined immunodeficiency. The signs and symptoms can evolve over time and may not appear simultaneously. Some patients present with some but not all of these symptoms and may be described as having atypical Omenn syndrome. The syndrome is not caused by a defined genetic defect. The majority of cases reported to date have hypomorphic mutations in RAG1 and RAG2 genes (11p13). Transmission is autosomal recessive. |
