Lightwood distinguishes this condition from one described by Fanconi3 in which the children had mental retardation, chronic renal disease, osteosclerosis, increased NPN, hypertension, elevated serum calcium, and death from renal failure. As there have been some cases of intermediate severity between the two, with a course leading to death, there has been some conjecture as to whether these are related syndromes representing the extremes of a broad spectrum. With no intent to state positively that these are unrelated diseases, this article
