SERPINA3 and attention deficit-hyperactivity disorder: We found that SNPs in genes HISTI1H1C, HSPA1B, PRPF3, and SERPINA3 showed at least nominal significant association with four other neuropsychiatric diseases [schizophrenia (SCZ), bipolar disorder, major depressive disorder (MDD), and attention-deficit hyperactivity disorder (ADHD)] in the Broad PGC database (https://data.broadinstitute.org/mpg/ricopili/) (Ripke and Thomas, 2017) (Table 2).
