Figure 3. Age regulated gene expression trends change faster in OPMD. (A) Expression trends in controls (grey) and expPABPN1 carriers (red). Similar expression trends were identified with k-means clustering using probe ID. (B) Examples of expression trends of 8 genes from clusters in A, in healthy controls (grey) or in exPABPN1 carriers at pre-symptomatic and symptomatic stages (red). Pre-symptomatic and symptomatic stages of OPMD are indicated.
