Phenylalanine Tolerance in Endogenous Depression
Published online by Cambridge University Press: 29 January 2018
Extract
Penrose (1935), in describing the first British patients with phenylketonuria, noted in their unaffected relatives a high incidence of paranoid illness in later life, and suggested that the heterozygous state might predispose to such breakdown. The 47 phenylketonuric families reported by Munro (1947) showed in unaffected relatives a similar high incidence of psychotic illness, which he (Munro, 1957) categorized as endogenous depression with paranoid features.
