Frequencies of the PAR4 rs773902 SNP in different world populations. (A) Allele frequencies in African and non-African populations, including those reported in the 1000 GP and HapMap projects as well as the Somali genotype data presented in this letter. (B) Continental frequencies of the A allele using populations reported in the 1000 GP and HapMap projects. The African panel is represented by 6 West African and 2 East African populations. Error bars represent relative standard deviation of the mean. (C) The 18 regions of the Somali republic. Birthplaces (ie, provinces of birth) of the study participants are highlighted in green.
