title: Intestinal enterokinase deficiency.
abstract: Deficiency of intestinal enterokinase results in failure to thrive, diarrhoea, anaemia, hypoproteinaemia and oedema. A case arising in the neonatal period is described, in which several of the characteristic features were lacking. Difficulties encountered in the diagnosis and methods of assay are discussed.
