Primary outcomePrimary: Concentration of Glutamine and Myoinositol — 2.61; 1.66; 2.23; 2.69 mM — p=0.001

Summary

The purpose of this study is to use various types of MRI and cognitive testing to evaluate changes in the brain and cognitive function that occur in subjects with ornithine transcarbamylase deficiency (OTCD) relative to healthy individuals
