Figure 2. The distribution of the TTR V122I allele in Africa.

Figure 2

DNA obtained from 2,700 subjects in various locales in Africa was genotyped for the V122I allele by either PCR single-nucleotide polymorphism analysis or complete exome sequencing. The color coding shows the greater frequency of the allele in the countries of coastal West Africa. TTR, transthyretin. (Reprinted by permission from ref. 18.)
