Urea cycle disorders are inherited disorders caused by the lack of an enzyme that removes ammonia from the bloodstream. Gene therapy is treatment given to change a gene so that it functions normally. Studying the treatment and metabolism of patients with urea cycle disorders may be helpful in developing new treatments for these disorders. PURPOSE: Two-part clinical trial to study the treatment and metabolism of patients who have urea cycle disorders. Condition Intervention Phase Amino Acid Metabolism, Inborn Errors

Extractions: Urea cycle disorders comprise a group of inborn errors of metabolism that represent unique gene-nutrient interactions whose significant morbidity arises from acute and chronic neurotoxicity associated with often massive hyperammonemia. Current paradigms of treatment are focused on controlling the flux of nitrogen transfer through the hepatic urea cycle by a combination of dietary and pharmacologic approaches. Evolving paradigms include the development of cell and gene therapies. Current research is focused on understanding the pathophysiology of ammonia-mediated toxicity and prevention of neural injury.

Prevention Abnormality of the urea cycle - hereditary; Urea cycle - hereditary abnormality The mainstay of treatment of these disorders is PROTEIN RESTRICTION. As protein is the source of nitrogen-containing chemicals in the diet, limiting protein will limit the amount of nitrogen-wastes. This reduces the stress on the hampered urea cycle. It is imperative that protein restriction be done with guidance from a health care professional who can make certain to balance the amount of protein needed for growth with that which will cause symptoms. It is extremely important for people with these disorders to AVOID FASTING. Patients with urea cycle abnormalities must also be very careful under times of stress, such as infections. Stress, such as fever, can cause the body to break down its own proteins and exceed the capacity of the abnormal urea cycle to dispose of the by-products. A sick-day plan should be formulated with your doctor to avoid all protein, consume high carbohydrate drinks, and stay hydrated.

Extractions: Multiple endocrine neoplasia type 1 (MEN1) consists of benign, and sometimes malignant, tumors (often multiple in a tissue) of the parathyroids, enteropancreatic neuroendocrine system, anterior pituitary, and other tissues. Skin angiofibromas and skin collagenomas are common. Typically, MEN1 tumors begin two decades earlier than sporadic tumors. Because of tumor multiplicity and the tendency for postoperative tumor recurrence, specialized methods have been developed for preoperative and intraoperative localization of many MEN1-associated tumors. Hemochromatosis is an inherited disorder of the small intestine that causes a person to absorb too much iron from their food. Over time, iron builds to toxic levels and destroys many organs. Symptoms of toxic iron excess can differ greatly from person to person. Symptoms might include fatigue or depression, arthritis, impotence and infertility, diabetes, heart disease, and liver disease or liver cancer. Fortunately, early detection and treatment will prevent iron excess and its toxic effects. Duchenne muscular dystrophy is one of the most common and most devastating human genetic diseases. Affecting 1 in 3,500 live-born males, it is an X-linked recessive disorder which strikes all world populations equally. It shows a very high spontaneous mutation rate making most cases refractory to genetic screening. No therapies exist which are capable of slowing the lethal progression of the disease: boys first show overt weakness in early school years, show a steady loss of muscle tissue, are wheel-chair-bound by age 14 yrs., and succumb to respiratory failure by age 20 unless ventilated.

Bacterial and mammalian cell expression systems are used to investigate the effects of naturally occurring mutations on the synthesis, processing and catalytic function of human OTCase.
