Error in Homozygote Classification

JAMA Psychiatry. 2014;71(7):840. doi:10.1001/jamapsychiatry.2014.871

In the article titled “Differential Effects of Common Variants in SCN2A on General Cognitive Ability, Brain Physiology, and Messenger RNA Expression in Schizophrenia Cases and Control Individuals” published in the June issue of JAMA Psychiatry (2014;71[6]:647-656. doi:10.1001/jamapsychiatry.2014.157), incorrect information appeared. In the third sentence under the BOLD fMRI Analyses header in the Results section, CC homozygotes should have read TT homozygotes. The full sentence should read as follows: “Among control individuals, TT homozygotes were most efficient; among schizophrenia cases, they were least efficient, and the interaction effect was significant (Montreal Neurological Institute coordinates: x = −36, y = 27, z = 33; familywise error–corrected P = .02; eFigure 4 in Supplement).” This article was corrected online.
