For a long time, this disease has caused confusion among the porphyrias because it presents with clinical symptoms and biochemical findings that can be similar to those found in other types of porphyrias. Here, we provide an overview of historical, clinical, biochemical, genetical, and other aspects of variegate porphyria that might be helpful in providing more insight into this rare disorder.    author contacts angela m. http://classicmotocrossimages.com/mbs-viagra-for-sale-generic-im/ Christiano, phddepartment of dermatology, columbia universitycollege of physicians and surgeons, 630 west 168th street, vc-1526new york, n.
