Correlation between IRF5 expression results obtained with different probes and in different experiments. Only results obtained with the same European population from the International HapMap Project (CEU) lymphoblastoid cell line (LCL) are compared. Bidimensional, nonparametric, multidimensional scaling was used for representation. Data from probes selected as representative are within the dashed circle. Labels for data from each probe indicate the number of the exon they target, including the 1A and 1C alternative exons and a variant sequence of exon 6 (6_v5), and UTR-pre and UTR-pro for the probes targeting the 3'UTR previous or posterior to rs10954213, respectively. Filled circles correspond to data from Kwan et al. , empty circles correspond to data from Stranger et al.  and empty squares correspond to data from Cheung et al. .
