General update from UKB Meeting for scientific community, 26 June 2014, London Access: >700 researchers, >100 applications, >50 approved, >40 have data Web-based questionnaires 1 st repeat of baseline assessment in 20,000 – completed 2012/13 Wrist-worn accelerometers in 100,000 – well underway Assays on samples from all participants – to complete mid 2015 Multimodal imaging in 100,000 - brain, cardiac and abdo MRI, whole body DEXA, & 3D carotid ultrasound – piloting in 2014 Genome wide genotyping of all 500,000 – to complete mid 2015 MRC UK Dementia Platform Proposal for prolonged cardiac rhythm monitoring in 100,000

Strategy for follow-up Key cohort-wide sources for data linkage: –Death registrations –Cancer registrations –Hospital episode data –Primary care data Questionnaires (web +/- mail) Other linkages sought or under discussion: –mental health minimum dataset; screening databases; disease registers/audits; imaging; histopathology reports/specimens; NHS dental records Future possible linkages: –occupational records; DWP ; HMRC; private medical records… Close liaison with wide range of data providers Working in collaboration with Farr Institute

Genotyping Chip Design Expert group (chair P Donnelly) considered issues of chip design, in a platform-agnostic way, before procurement. Specific sets of SNPs chosen for inclusion, with further advice from experts in particular areas. Affymetrix used their imputation-aware algorithms to choose additional SNPs to provide good coverage of the genome. For common variants, accuracy of imputed genotypes typically > 95%. Imputation accuracy within UK Biobank will be higher than with current approaches.
