Before a PRS can be considered for implementation, it needs rigorous evaluation, using performance measures that can inform about its future clinical value. External risk scores are assessments of anything and everything that could threaten your business from outside the company. We evaluated the performance of current polygenic T2D prediction. A recent GWAS based on individuals of European ancestry identified 403 independent genetic variants associated with type 2 diabetes. PGS Catalog - PGS000729 / Type 2 diabetes (Polygenic Score) Polygenic risk scores (PRSs) . For polygenic risk score analyses, linkage disequilibrium pruning was performed in PLINK 1.9 based on a pairwise R 2 of 0.5 and a window of 50 SNPs, shifting 5 SNPs at a time. Genome-wide association studies (GWAS) may have reached their limit of detecting common type 2 diabetes (T2D)-associated genetic variation. Polygenic risk scores (PRS) provide an opportunity to understand risk factors since they reflect etiologic pathways from the entire genome. Likewise, a polygenic risk score based approach may reduce invasive diagnostic procedures as demonstrated in Celiac disease. AU - Li, Josephine H. AU - Szczerbinski, Lukasz.

Genotyping, quality control, and imputation procedures have been previously described in detail . Most of these existing risk scores performed better in their original population than in the two Chinese validation populations, indicating that a race- or country-specific risk score may be needed. Yet, its genetic predisposition is largely unknown. Unlike 23andMe's other health reports, which inspect one or two genes for mutations with big, well-understood effects, its new diabetes test uses something called a polygenic risk score. An approach for converting genetic data into a predictive measure of disease susceptibility is to add the risk effects of loci into a polygenic risk score. A fine, short summary concluding that it is a good "engagement tool" but otherwise of no clinical use can be found here.. omim summarizes the latest research..
