rs11545787 (P=1.4 × 10−8) is a 3′UTR variant of RASD1 (Supplementary Fig. 7), a G protein signaling activator24 and is a promoter histone mark for six cell types (H1, umbilical vein endothelial, B-lymphocyte, lung fibroblasts, skeletal muscle myoblasts and epidermal keratinocyte), in a DHS for seven cell types (skeletal muscle myoblasts, fibroblast, hepatocytes, medulloblastoma, epidermal melanocytes, pancreatic islets and fibroblasts) (Supplementary Table 16). The gene discussed is RASD1; the disease is medulloblastoma.
