Figure 1From: Different atrophy-hypertrophy transcription pathways in muscles affected by severe and mild spinal muscular atrophy Hierarchical cluster analysis of SMAI and III profiles. This dendrogram was constructed with the expression profiles of SMA muscle biopsies using the complete linkage cluster method and the Euclidean distance measure. Patients with SMA are clearly divided into two groups corresponding to the clinical classification: cluster 1 for the more severe type I and cluster 2 for the milder type III.Back to article page
