Figure 2From: A common 56-kilobase deletion in a primate-specific segmental duplication creates a novel butyrophilin-like proteinWorld-wide distribution of the BTNL8_BTNL3-del allele in different human populations. Genotype analysis of populations is shown over a map of the world. The deletion frequency is indicated by the black part of the pie in the chart. Total number of individuals genotyped is given in red.Back to article page
