We did not replicate the finding that the chromosome regions near CENPW, GLIS3, BCL11A or THADA co-localised between type 1 and type 2 diabetes (H4PP CENPW=0.12, GLIS3=0.29, BCL11A=0.28, THADA not examined as no type 1 diabetes association existed in the region [FDR=0.07]). The gene discussed is BCL11A; the disease is type 1 diabetes mellitus.
