WebThe second main compound, pheochromocytoma, is reported with a variable penetrance, from 10 to 80% cases, depending on the mutation of RET. Pheochromocytoma constitutes the main disease to screen in patients with RET mutations. Pheochromocytoma clinical and biochemical diagnosis, as well as the way to treat it are thus crucial. WebUp to 40 percent of pheochromocytomas result from genetic mutations (also known as variants) inherited from parents. If either parent carries a known variant, you have a 50-50 chance of inheriting it. But inheriting one of these genes doesn't guarantee you'll develop pheochromocytoma. jerusalem stone new orleans
