When using the BPRS deficiency energy factor score as the dependent variable, we found that oxytocin level explained a significant amount of the variance in the BPRS deficiency energy factor score in Step 1 (F = 6.40, p < 0.05; R2 = 0.076; β = −0.28). The gene discussed is OXT; the disease is hyperinsulinemic hypoglycemia, familial, 4.
