The phrase "ancestry ascertained" is correct and usable in written English.
It can be used in contexts discussing the determination or verification of one's lineage or family history.
Example: "After months of research, I finally received the results confirming my ancestry ascertained through DNA testing."
Alternatives: "lineage confirmed" or "heritage established".
To maximize the likelihood of identifying medium penetrance genetic variants influencing T2D-risk, a total of 591 individuals of British ancestry, ascertained for early-adult onset (sample 1, n = 84), and/or family history of T2D (at least 1 sibling affected, sample 2, n = 507) were included (Table 1).
Here, we report a fine-mapping analysis of the 9q31.2 susceptibility locus using 43 160 cases and 42 600 controls of European ancestry ascertained from 52 studies and a further 5795 cases and 6624 controls of Asian ancestry from nine studies.
All subjects lived in Calabria (southern Italy) and their Calabrian ancestry was ascertained up to the grandparents' generation.
Marker informativeness for ancestry can be ascertained through the absolute value of the difference in the frequency of a particular allele observed for 2 ancestral populations.
An understanding of the relationship among these different populations and ascertaining ancestry informative markers (AIMs) that can discern East Asian substructure will undoubtedly facilitate accurate interpretation of such studies[5].
Setting: all subjects were born in Calabria (southern Italy) and their ancestry in the region was ascertained up to the grandparents.
These SNPs were ascertained to be ancestry-sensitive on the continental level as described in detail elsewhere (Lao, et al., 2006; Lao, et al., 2007; Kersbergen, et al., 2009; Corach, et al., 2010).
All the subjects were born in Calabria (southern Italy) and their ancestry in the region had been ascertained up to the grandparents' generation.
All the subjects were born in Calabria (Southern Italy) and their ancestry in the region has been ascertained up to the grandparents' generation.
Suitability of the 24 ascertained SNPs to recover continental ancestry was checked by means of performing a STRUCTURE analysis (Pritchard, et al., 2000) in the HGDP-CEPH panel.
However, to increase power, the allelic architecture of the population from which these case control series are ascertained needs to have similar ancestry and, ideally, the same linkage disequilibrium (LD) structure.
