Some examples of biochemical traits correlated with two or fewer psychiatric GWAS were albumin and ADHD (rg = −0.151), mean corpuscular volume and AN (rg = 0.087), mean sphered cell volume and SZ (rg = 0.06), and creatinine with bipolar disorder (BIP) and SZ (SZ: rg = −0.07; BIP: rg = −0.106). Here, ALB is linked to attention deficit-hyperactivity disorder.
