Deciphering the shared genetic basis of distinct cancers has potential to elucidate carcinogenic mechanisms and inform broadly applicable risk assessment efforts. Here, we undertake genome-wide association studies (GWAS) comprehensive evaluations heritability pleiotropy across 18 cancer types in two large, population-based cohorts: UK Biobank (408,786 European ancestry individuals; 48,961 cases) Kaiser Permanente Genetic Epidemiology Research on Adult Health Aging cohorts (66,526 16,001...

A genome-wide association study (GWAS) of prostate cancer in Kaiser Permanente health plan members (7,783 cases, 38,595 controls; 80.3% non-Hispanic white, 4.9% African-American, 7.0% East Asian, and 7.8% Latino) revealed a new independent risk indel rs4646284 at the previously identified locus 6q25.3 that replicated PEGASUS (N = 7,539) Multiethnic Cohort 4,679) with an overall P 1.0 × 10(-19) (OR, 1.18). Across locus, exhibited strongest expression SLC22A1 (P 1.3 10(-23)) SLC22A3 3.2...

Abstract Prostate-specific antigen (PSA) levels have been used for detection and surveillance of prostate cancer (PCa). However, factors other than PCa—such as genetics—can impact PSA. Here we present findings from a genome-wide association study (GWAS) PSA in 28,503 Kaiser Permanente whites 17,428 men replication cohorts. We detect 40 significant ( P <5 × 10 −8 ) single-nucleotide polymorphisms (SNPs): 19 novel, 15 previously identified (14 which were also PCa-associated), 6 PCa only....

Abstract Genome-wide association study–identified prostate cancer risk variants explain only a relatively small fraction of its familial relative risk, and the genes responsible for many these identified associations remain unknown. To discover novel genetic loci possible causal at previously loci, we performed transcriptome-wide study in 79,194 cases 61,112 controls European ancestry. Using data from Genotype-Tissue Expression Project, established models to predict gene expression across...

Abstract Here we train cis -regulatory models of prostate tissue gene expression and impute transcriptome-wide for 233,955 European ancestry men (14,616 cancer (PrCa) cases, 219,339 controls) from two large cohorts. Among 12,014 genes evaluated in the UK Biobank, identify 38 associated with PrCa, many replicating Kaiser Permanente RPGEH. We report association elevated TMPRSS2 increased PrCa risk (independent a previously-reported variant) tumoral : ERG fusion-oncogene The Cancer Genome...

Risk factors that contribute to inter-individual differences in the age-of-onset of allergic diseases are poorly understood. The aim this study was identify genetic risk variants associated with age at which symptoms disease first develop, considering information from asthma, hay fever and eczema.

For each individual, we identified earliest and/or eczema diagnosed performed a genome-wide association...

ABSTRACT Genetic factors that influence etiologic mechanisms shared across cancers could affect the risk of multiple cancer types. We investigated polygenic score (PRS)-specific pleiotropy 17 in two large population-based cohorts. The study population included European ancestry individuals from Epidemiology Research on Adult Health and Aging cohort (16,012 cases, 50,552 controls) UK Biobank (48,969 359,802 controls). selected known independent variants published GWAS to construct a PRS for...

Abstract Deciphering the shared genetic basis of distinct cancers has potential to elucidate carcinogenic mechanisms and inform broadly applicable risk assessment efforts. However, no studies have investigated pan-cancer pleiotropy within single, well-defined populations unselected for phenotype. We undertook novel genome-wide association (GWAS) comprehensive evaluations heritability across 18 cancer types in two large, population-based cohorts: UK Biobank (413,870 European ancestry...

BACKGROUND Benign tissue from a tumor-containing organ is commonly the only available source for obtaining patient's unmutated genome use in cancer research. While it critical to identify histologically normal that independent of tumor lineage, few additional considerations are applied choice this material such measurements. METHODS Normal formalin-fixed, paraffin-embedded seminal vesicle, and urethral tissues, addition whole blood, were collected 31 prostate patients having undergone...

ABSTRACT The potential association between rare germline genetic variants and prostate cancer (PrCa) susceptibility has been understudied due to challenges with assessing variation. Furthermore, although common risk for PrCa have shown limited individual effect sizes, their cumulative may be of similar magnitude as high penetrance mutations. To identify associated susceptibility, better characterize the mechanisms disease variants, we analyzed large population-based cohorts, custom...
