MAP2K5 and obesity due to melanocortin 4 receptor deficiency: We then manually looked up the biological functions of these BSAGs by searching the literature and multiple databases and identified 14 positively-correlated BSAGs (BRAP, CHCHD5, CPT1C, GPR1, LDLR, MAP2K5, PLEKHS1, SLC30A8, ST3GAL2, STX16, ZFHX3, ZGRF1, ZNF395 and ZPLD1) that were associated with “obesity” (Table S4), which is a manifestation of an enlarged-body-sized phenotype.
