A family with a dominant form of idiopathic Fanconi syndrome leading to renal failure in adult life.

Three members of a family previously reported by Sheldon, Luder and Web in 1961 as having a benign tubular renal disease have since developed renal failure. One received a renal transplant but died following this. This form of apparently primary, dominantly-inherited Fanconi syndrome is a mild disease in childhood, but leads to renal failure in adult life.
