Figure 1From: Whole blood transcriptional profiling in ankylosing spondylitis identifies novel candidate genes that might contribute to the inflammatory and tissue-destructive disease aspectsClustering on top 3% most variable genes. Unsupervised hierarchical clustering based upon the top 3% most variable genes (585 genes) showed good delineation between the patient and control samples with six controls and five AS samples misclassifying. The non-perfect classification suggests non-disease related factors also drive the gene expression patterns.Back to article page
