FKBP10 and atrial fibrillation: Validation showed that COL6A3 and FKBP10 were significantly up-regulated in AF in the GSE41177 dataset and trended towards high expression in stable CAD in the GSE56885 dataset (Fig. 4D-E) Finally, COL6A3 and FKBP10 were identified as hub genes potentially associated with stable CAD and AF.
