Figure 2From: Exome sequencing of a family with lone, autosomal dominant atrial flutter identifies a rare variation in ABCB4 significantly enriched in cases Sequencing electropherograms . Electropherograms of control (upper) and atrial flutter/fibrillation-affected (lower) subjects with rs58238559 in the ABCB4 gene. Heterozygosity is indicated by the presence of two peaks corresponding to T and C (in the box).Back to article page
