Figure 1From: Potassium channel gene mutations rarely cause atrial fibrillationSize and Structure of the KCNE1-5 and KCNJ2 genes. Thin lines represent introns while exons are depicted as boxes. Small boxes are non-coding regions and large boxes are coding regions. Arrows indicate the location of PCR primers. The genomic size of each gene is presented to the right of each figure.Back to article page
