a
Six related studies used samples collected from Navajo people and White Mountain Apache children spanning from 1994 to 2009. Some studies did not report the number of Navajo individuals and simply reported aggregate data from multiple tribes, meaning the number does not distinguish between different tribal groups. We report the highest total number reported because it was unclear which samples were shared or unique to the studies.
b
Six studies included a total of 70 Navajo samples.
c
Studies in these categories did not sequence human DNA.
