McCarthy et al. (19) identified 58 genes potentially associated with BD and brain regions associated with BD through a genome-wide association study (GWAS) and classified 22 of these genes with anatomically distinct expression patterns into three gene expression clusters (C1: ATP6V1G3, GATA5, GPRB81, NGF, NPAS3, PAX1, SPERT, TNR, ZMIZ1; C2: ADCY2, CACNB3, DLG2, KDM5B, KIF1A, MAPK10, RIMBP2, UBE2E3, UBR1; C3: ANK3, STK39, FAM155A, SIPA1L2). The gene discussed is GATA5; the disease is Behcet disease.
