Over 2,500 ANK2 variants listed in the Exome Aggregation Consortium at the Broad Institute were mapped to a protein domain. The length of the domain along the x-axis is based on percentage of genomic DNA that makes up that domain. Variants per kilobase on the y-axis depicts the average number of variants/Kb/domain. MBD, membrane-binding domain; SBD, spectrin-binding domain; DD, death domain; RD, regulatory domain; UTR, untranslated region.
