Abstract The genetic contributions to breast cancer development among Latinas are not well understood. Here we carry out a genome-wide association study of in and identify significant risk variant, located 5′ the Estrogen Receptor 1 gene ( ESR1 ; 6q25 region). minor allele for this variant is strongly protective (rs140068132: odds ratio (OR) 0.60, 95% confidence interval (CI) 0.53–0.67, P =9 × 10 −18 ), originates from Indigenous Americans uncorrelated with previously reported variants at...
More than 180 single nucleotide polymorphisms (SNPs) associated with breast cancer susceptibility have been identified; these SNPs can be combined into polygenic risk scores (PRS) to predict risk. Because most were identified in predominantly European populations, little is known about the performance of PRS non-Europeans. We tested a 180-SNP Latinas, large ethnic group variable levels Indigenous American, European, and African ancestry.We conducted pooled case-control analysis US Latinas...
Women of Latin American origin in the United States are more likely to be diagnosed with advanced breast cancer and have a higher risk mortality than non-Hispanic White women. Studies U.S. Latinas women reported high incidence HER2 positive (+) tumors; however, factors contributing this observation unknown. Genome-wide genotype data for 1,312 patients from Peruvian Genetics Genomics Breast Cancer Study (PEGEN-BC) were used estimate genetic ancestry. We tested association between status...

<div>AbstractBackground:<p>A substantial portion of the genetic predisposition for breast cancer is explained by multiple common variants relatively small effect. A subset these variants, which have been identified mostly in individuals European (EUR) and Asian ancestries, combined to construct a polygenic risk score (PRS) predict risk, but prediction accuracy existing PRSs Hispanic/Latinx (H/L) remain low. We assessed performance several PRS panels with without addition...

Abstract The purpose of this study is to describe Chilean families having hereditary Gastric Cancer (GC) presenting pathogenic mutations in BRCA 2 (c.4740_4741dup NP_000050.3:p.Glu1581fs), ATM (c.3381_3384del NP_000042.3:p.Gln1128fs) and Protector Telomers 1 (POT1, 1087C&gt;T:p.Arg363Ter) genes. Only one diffuse GC (HDGC) family with a CDH1 mutation has been reported, suggesting low frequency detection population. Whole exome sequencing (WES) was performed using the Agilent SureSelect...
A recent study reported the non-synonymous G534E (rs7080536, allele A) variant in HABP2 gene as causal familial non-medullary thyroid cancer (NMTC).The objective of this was to evaluate causality TCUKIN study, a multi-center population based NMTC cases from British Isles.A case-control analysis rs7080536 genotypes performed using 2,105 and 5,172 UK controls.Cases comprised cases. Patients sub-groups with papillary (N=1,056), follicular (N=691) Hurthle cell (N=86) TC were studied separately....
The G allele of the rs6983267 single-nucleotide polymorphism, located on chromosome 8q24, has been associated with increased risk several cancer types. association between rs6983267G and thyroid (TC) tested in different populations, mostly European ancestry, led to inconclusive results. While significant associations have reported British Polish no detected populations from Spain, Italy USA. To further investigate role TC susceptibility, we evaluated genotypes three continental ancestry...
Thyroid cancer (TC) is the second most common among Hispanic women. Recent genome-wide association (GWA) and candidate studies identified 6 single nucleotide polymorphisms (SNPs; rs966423, rs2439302, rs965513, rs6983267, rs944289, rs116909374), associated with increased TC risk in Europeans but their effects on disease have not been comprehensively tested Hispanics. In this study, we aimed to describe main clinicopathological manifestations evaluate of known SNPs a population. We analyzed...
