Symptoms
The symptoms are very similar to graft-versus-host disease (GVHD). This is because the patients have some T cells with limited levels of recombination with the mutant RAG genes. These T cells are abnormal and have a very specific affinity for self antigens found in the thymus and in the periphery. Therefore, these T cells are auto-reactive and cause the GVHD phenotype.
Symptoms include:
- Desquamation (shedding the outer layers of skin)
- Chronic diarrhea
- Erythroderma (widespread reddening of the skin)
- Hepatosplenomegaly (simultaneous enlargement of both the liver and the spleen)
- Leukocytosis (elevation of the white blood cell count)
- Lymphadenopathy (swelling of one or more lymph nodes)
- Persistent bacterial infections
- Elevated serum IgE

Famous quotes containing the word symptoms:
“In retirement, only money and symptoms are consequential.”
—Mason Cooley (b. 1927)
“Protest, evasion, merry distrust, and a delight in mockery are symptoms of health: everything unconditional belongs in pathology.”
—Friedrich Nietzsche (1844–1900)
“For anyone addicted to reading commonplace books ... finding a good new one is much like enduring a familiar recurrence of malaria, with fever, fits of shaking, strange dreams. Unlike a truly paludismic ordeal, however, the symptoms felt while savoring a collection of one man’s pet quotations are voluptuously enjoyable ...”
—M.F.K. Fisher (1908–1992)
