Henoch-Schonlein purpura (HSP), also known as IgA vasculitis, is an acute systemic immune-mediated small vessel vasculitis resulting in palpable purpura without thrombocytopenia, variable manifestations of abdominal pain, arthritis or arthralgia, proteinuria, hematuria, and IgA deposits in small vessels (which may be demonstrated on the skin or kidney biopsy) [1–4]. This evidence concerns the gene CD79A and hereditary spastic paraplegia.
