[Ancestry which is an admixture of more than one defined ancestral population. The degree and type of admixture may vary within a population and the accuracy of classification requires well-defined reference samples]
[Includes indigenous individuals of North, Central and South America, descended from the original human migration into the Americas from Siberia. We note that there does not appear to be a suitable reference population for this category and efforts are required to fill this gap.]
[Includes individuals who either self-report or have been described by authors as African American or Afro-Caribbean. This category also includes individuals who genetically cluster with reference populations from this region, for example 1000 Genomes and/or HapMap ACB or ASW populations. We note that there is likely to be significant admixture with European ancestry populations.]
[Includes individuals who self-report or were described by authors as Middle Eastern, North African, Persian or one of the subpopulations from this region (e.g. Saudi Arabian). We note there is heterogeneity in this category with different degrees of admixture as well as levels of genetic isolation. We note that there does not appear to be a suitable reference population for this category and efforts are required to fill this gap.]
[Includes individuals that either self-report or have been described by authors as Oceanian or one of the sub-populations from this region (e.g. Native Hawaiian). We note that there does not appear to be a suitable reference population for this category and efforts are required to fill this gap.]
