Given the emerging evidence supporting the notion that vital genetic markers for psychiatric disorders are normally associated with the disease across different ethnic populations65 (e.g., psychiatric risk loci in ZNF804A, FADS1, and VRK2 show significant associations in both Europeans and East Asians66–71), we then examined whether LRFN5 and DCC were also associated with depression in Han Chinese subjects through MAGMA gene-level analyses using a published Han Chinese GWAS dataset (5303 cases and 5337 controls)24. This evidence concerns the gene DCC and major depressive disorder.
