Quality control and removal of technical variation of NMR metabolic biomarker data in ~120,000 UK Biobank participants

Abstract: Metabolic biomarker data quantified by nuclear magnetic resonance (NMR) spectroscopy in approximately 121,000 UK Biobank participants has recently been released as a community resource, comprising absolute concentrations and ratios of 249 circulating metabolites, lipids, and lipoprotein sub-fractions. Here we identify and characterise additional sources of unwanted technical variation influencing individual biomarkers in the data available to download from UK Biobank. These included sample preparation time, sh… Show more

“…We classified the Nightingale metabolite measurements and the clinical biomarkers into the following 10 different biological classes or physiological systems based on known biology: lipids, amino acids, liver, glucose-related/glycolysis, renal, hormones, ketone bodies, bone and joint, inflammatory, and immune ( Tables S1 A and S1B). The Nightingale metabolite measurements that are available for 121,695 UKB participants mainly include lipoprotein lipids, fatty acids and their compositions, and various other low-molecular-weight metabolites 24 ( Table S1 A). The clinical biomarkers, which have been measured in nearly all the UKB participants, are more diverse and relate to glucose and lipid metabolism, renal and liver function, and others ( Table S1 B).…”

“…Concentrations of 168 blood metabolites (107 “non-derived” metabolites and 61 composite metabolites) and 81 metabolite ratios, pertaining to lipoprotein lipids, fatty acids and their compositions, and various other low-molecular-weight metabolites, were measured in a subset of randomly selected 121,695 UKB participants by Nightingale Health using nuclear magnetic resonance (NMR) spectroscopy 24 ( Table S1 A). Metabolite measurements were normalized for known sources of technical variation using the ukbnmr R package ( https://github.com/sritchie73/ukbnmr/ ).…”

“…A random subset of 118 466 individuals was profiled for plasma metabolites using a high-throughput 1H-NMR metabolomics (Nightingale Health; biomarker quantification version 2020), which includes 249 metabolites. A natural logarithm transformation of each metabolite was performed for the analysis.…”

“…These data are now available to approved researchers through the UK Biobank Showcase for all aspects of public health research. Many studies are already using these biomarker data, spanning applications related to, for instance, risk prediction, causal analyses, genetic discovery and drug target validation [9][10][11][12][13][14][15][16][17][18] .…”
