Plasma amino acid levels in Huntington's chorea

Abstract

Concentrations of plasma amino acids in nine patients with Huntington's chorea and nine control patients were studied while diet and drug therapy were controlled. Significantly low values for threonine, alanine, isoleucine, leucine, lysine and histidine were found in the Huntington's chorea patients. However, since different investigators have failed to establish a consistent pattern of abnormality, it is considered that the findings are probably due to non-specific factors.
