Fig. 5: Recent origin of the KCNQ1 risk allele.
From: The history and geographic distribution of a KCNQ1 atrial fibrillation risk allele

Histogram of coalescent estimates of ancestral age of chromosome 11 single nucleotide variants shared by the 2 whole-genome-sequenced KCNQ1 risk allele carriers, and absent from 99 CEPH-Utah (CEU) 1000 Genomes samples. The dotted line indicates the estimated age of the KCNQ1 risk allele, corresponding to 182 generations ago (79–719 generations, ±97.5% CI).
