A case of Hartnup disease.

This new disease was first described last year by Dr. Hart and Professor Dent and their colleagues (Baron, Dent, Harris, Hart and Jepson, 1956) under the title 'Hereditary pellagra-like skin rash with temporary cerebellar ataxia, constant aminoaciduria, and other bizarre biochemical features'. The name 'Hartnup disease'-after the family then described-was later used in a reference to the syndrome by Harris (1957) and is that at present preferred by the original authors. No further accounts of cases have yet been published in this country and it seemed, therefore, that the following case was worthy of record. A brief reference to two further cases in Holland has been made by Jonxis (1957).
