The incidences of depression and disruptive behavior were significantly lower in participants that carried the GRIN1 T/T genotype (SNP rs4880213) than in members of the two other groups; this result was consistent with Georgi's study, which showed that the T allele was less frequent in schizophrenia patients with a lifetime history of depression than in control. The gene discussed is GRIN1; the disease is depressive symptom measurement.
