Abstract
Plasma creatine phosphokinase (CPK) activity was determined in single samples of 9 monozygotic and 14 dizygotic twin pairs chosen from an earlier study on the basis of their having been discordant for clinical schizophrenia. The correlations within the MZ pairs was 0.89, and within the DZ pairs was 0.40. The results support a conclusion of genetic control of plasma CPK activity. The mean levels of activity were not abnormal, however.
