from discrete genetic ancestry clusters towards the continuum of genetic ancestries when considering PGSs.#Using two large biobank datasets, a study shows that the accuracy of polygenic scores decreases as a function of relatedness at the individual level when modelling genetic ancestry as a continuum...
In November of 2022,Hughes et al.published an updated PGS for breast cancer they call “multiple-ancestry polygenic risk score” or “MA-PRS”. The authors developed a breast cancer risk assessment with greater accuracy for cisgender women of non-European ancestry by adjusting the weight given ...
These estimates are within 7% of the genome-wide average and are conservative, under-estimating the actual proportion of Native American ancestry. Figure 5 Accuracy and performance of the 324 AIMs. The root mean square error (RMSE) between Native American ancestry estimates using AIMs and the ...
Ancestryalso provides shared surnames, with clickable links to the number of people in your matches tree with that surname, plus common locations. X-DNA X-DNA is probably the most underutilized DNA matching tool. While each of the vendors actually test the X chromosome, only one,FamilyTreeDNA...
In my case, I took the original Ancestry test and, later, the V2 test, which is why you see my name twice on the list, above, of DNA tests that I have access to. Updated Regions Ancestry has updated the regions and subregions that they report in their ethnicity, now “Ancestral ...
as exemplified by the Latin America Genomics Consortium. Further advancing such diversity will facilitate greater PRS accuracy in populations of non-European ancestry [112,113]. By addressing these research (and consequently health) inequities, the full and equitable potential of PRS will also be real...

AncestryDNA further found a phase error rate using the Underdog algorithm of 0.64% with a training set of 502,212 samples and suggested accuracy would improve with larger phasing panels [21]. Download: Download high-res image (298KB) Download: Download full-size image Fig. 2. Illustration ...
Historically, most large-scale immunogenomic studies—those exploring the association between genes and disease—were conducted with a bias toward individuals of European ancestry. Corey T. Watson, Ph.D., assistant professor ... Jun 29, 2021 ...
