Fanconi syndrome

A group of kidney disorders that cause protein, sugar, minerals, and other nutrients to be lost in the urine. Symptoms include weakness, bone pain, and passing a greater than normal amount of urine. One form of Fanconi syndrome is inherited and is usually found in infants. Fanconi syndrome may also be caused by other diseases, a lack of vitamin D, or exposure to heavy metals or chemicals, including certain anticancer drugs.
