GBE1 and adult polyglucosan body disease: Table 1 notes the top 30 differentially expressed proteins identified by ≥2 peptides with adjusted p-values and percent expression changes. The most statistically significant differentially expressed protein was GBE1 (9.3% in APBD subjects vs. controls; adjusted p-value 5.87E-40), an important ‘positive control.’ The top 30 and the entire set of 531 differentially expressed proteins are detailed in Table 1 and Supplementary Table 1, respectively.
