Metabolomics in epidemiology: sources of variability in metabolite measurements and implicationsJoshua N Sampson
Corresponding Author Joshua N Sampson, Division of Cancer Epidemiology and Genetics, National Cancer Institute, 6120 Executive Blvd, Rockville, MD 20852
Cancer Epidemiol Biomarkers Prev 22:631-40. 2013..Here, the authors assess the variability of a large subset of metabolites and evaluate the implications for epidemiologic studies...
A two-platform design for next generation genome-wide association studiesJoshua N Sampson
Biostatistics Branch, DCEG, National Cancer Institute, Rockville, Maryland 20852, USA
Genet Epidemiol 36:400-8. 2012..However, the loss of power due to imputation can be more substantial if the relative risks for rare variants are significantly larger than those previously observed for common variants...
Selecting SNPs to identify ancestryJoshua N Sampson
National Cancer Institute, Bethesda, MD, USA
Ann Hum Genet 75:539-53. 2011..We demonstrate that selection procedures based on this estimate produce small sets of SNPs that can accurately predict ancestry. We also provide a list of the 100 optimal SNPs for identifying ancestry...
