Genome-wide association studies have identified thousands of genetic variants associated with non-small cell lung cancer (NSCLC), however, it is still challenging to determine the causal and improve disease risk prediction. Here, we applied massively parallel reporter assays perform NSCLC variant-to-function mapping at scale. A total 1249 candidate were evaluated, 30 potential within 12 loci identified. Accordingly, proposed three architectures underlying susceptibility: multiple in a single haplotype block (e.g. 4q22.1), blocks 5p15.33), variant 20q11.23). We developed modified polygenic score using from Chinese populations, improving performance prediction 450,821 Europeans UK Biobank. Our findings not only augment understanding architecture susceptibility but also provide strategy advance stratification.

Abstract Great efforts are being made to develop advanced polygenic risk scores (PRS) improve the prediction of complex traits and diseases. However, most existing PRS primarily trained on European ancestry populations, limiting their transferability non-European populations. In this article, we propose a novel method for generating multi-ancestry Polygenic Risk scOres based enSemble PEnalized Regression models (PROSPER). PROSPER integrates genome-wide association studies (GWAS) summary statistics from diverse populations ancestry-specific with improved predictive power minority The uses combination $${{{{{{\mathscr{L}}}}}}}_{1}$$ L 1 (lasso) $${{{{{{\mathscr{L}}}}}}}_{2}$$ 2 (ridge) penalty functions, parsimonious specification parameters across an ensemble step combine generated different parameters.

Polygenic risk scores (PRSs) are now showing promising predictive performance on a wide variety of complex traits and diseases, but there exists substantial gap across populations. We propose MUSSEL, method for ancestry-specific polygenic prediction that borrows information in summary statistics from genome-wide association studies (GWASs) multiple ancestry groups via Bayesian hierarchical modeling ensemble learning. In our simulation data analyses four distinct studies, totaling 5.7 million participants with ancestral diversity, MUSSEL shows compared to alternatives. For example, has an average gain R

The genetic composition of embryos generated by in vitro fertilization (IVF) can be examined with preimplantation testing (PGT). Until recently, PGT was limited to detecting single-gene, high-risk pathogenic variants, large structural and aneuploidy. Recent advances have made genome-wide genotyping IVF feasible affordable, raising the possibility screening for their risk polygenic diseases such as breast cancer, hypertension, diabetes, or schizophrenia. Despite a heated debate around this new technology, called embryo (PES; also PGT-P), it is already available patients some countries. Several articles studied epidemiological, clinical, ethical perspectives on PES; however, comprehensive, principled review emerging field missing.

Abstract INTRODUCTION We estimated the ages when associations between Alzheimer's disease (AD) genes and brain volumes begin among middle‐aged older adults. METHODS Among 45,616 dementia‐free participants aged 45–80, linear regressions tested whether genetic risk score for AD (AD‐GRS) had age‐dependent with 38 regional magnetic resonance imaging volumes. Models were adjusted sex, assessment center, ancestry, intracranial volume. RESULTS AD‐GRS modified effect of age (per decade) on amygdala (−0.41 mm 3 [−0.42, −0.40]); hippocampus (−0.45 [−0.45, −0.44]), nucleus accumbens (−0.55 [−0.56, −0.54]), thalamus (−0.38 [−0.39, −0.37]), medial orbitofrontal cortex (−0.23 [−0.24, −0.22]). Trends began by 45 thalamus, 48 hippocampus, 51 amygdala, 53 cortex. An excluding apolipoprotein E ( APOE ) was additionally associated entorhinal middle temporal cortices.

The 313-variant polygenic risk score (PRS313) provides a promising tool for breast cancer prediction. However, evaluation of the PRS313 across different European populations which could influence estimation has not been performed. Here, we explored distribution using genotype data from 94,072 females without cancer, European-ancestry 21 countries participating in Breast Cancer Association Consortium (BCAC) and 225,105 female participants UK Biobank. mean differed markedly countries, being highest south-eastern Europe lowest north-western Europe. Using overall to categorise individuals leads overestimation underestimation some respectively. Adjustment principal components explained most observed heterogeneity PRS. Country-specific PRS distributions may be used calibrate categories countries.
