“…First, we highlight the variability in PGS performance along the continuum of genetic ancestry, even within traditionally defined homogenous populations. With the increasing recognition that genetic ancestries are not discrete but rather continuous [15][16][17][18][19] , the individual-level accuracy introduced here provides a powerful tool to study PGS performance along the genetic ancestry continuum. Given the pervasive variable PGS accuracy across individuals, incorporating individual-level metrics of PGS performance can improve the utility of PGS.…”

“…PGS accuracy is traditionally assayed using population-level metrics of accuracy (e.g., R 2 ), thus assuming some level of homogeneity across individuals within the considered population 2,11,15 . However, homogeneous populations are an idealized concept that only roughly approximate human populations; human diversity exists along a genetic ancestry continuum without clearly defined clusters and with various correlations between genetic and socio-environmental factors [15][16][17][18][19][20] . Grouping individuals into genetic ancestry clusters obscures the impact of individual variation on PGS accuracy.…”

“…These racial categories persist to this day, and it is therefore important to better comprehend the differences between race, ethnicity and genetic ancestry, and their subsequent utility for precision oncology. Indeed, although being distinct concepts, they are often collected and used variably in precision oncology and other related activities (Adigbli, 2020;Krainc and Fuentes, 2022;Bonham, Green and Pérez-Stable, 2018;Popejoy et al, 2020).…”

“…In contrast, genetic ancestry is a biological attribute that "involves the comparison of a large number of DNA variants measured in an individual with the frequencies of these variants in reference populations sampled from across the world" (Krainc and Fuentes, 2022;Jorde and Bamshad, 2020).…”

“…Race may be a social construct, but ancestry is genetic. 7 Until we determine that the lower lung volumes observed in patients who identify with certain ''races'' are not in some part due to common genetic ancestry, we should be careful regarding how we proceed. We want to avoid having ''racial adjustments'' mask underlying pathologic lung function, but also not have normal lung function interpreted as pathologic, abnormal, or inferior.…”
