LEP and type 2 diabetes mellitus: We investigated genetic correlations between early-onset AN and 62 traits prioritized from six categories based on previous evidence from AN (5,17): psychiatric (i.e., schizophrenia, major depressive disorder), anthropometric (i.e., weight, height), glycemic (i.e., type 2 diabetes, insulin resistance), lipid related (i.e., high-density lipoprotein cholesterol, triglycerides, leptin), reproductive (i.e., age at menarche, age at menopause), and education and intelligence (i.e., IQ, college completion).
