Recently, recessively inherited mutations in the IL36RN gene, which encodes interleukin-36 receptor antagonist (IL-36Ra), have been demonstrated to be the cause of familial GPP, a condition termed DITRA (deficiency of IL-36Ra).

The treatment options used are various; however, its typical cyclic recurrences, which induce important physical and psychological morbidity, may render this pathology difficult to treat. Read More
