N1 - Funding Information:
GRANT SUPPORT: Amsterdam Public Health Institute Methodology travel grant VVO; KNAW Academy Professor Award (PAH/6635) to DIB. JvD is supported by NWO Large Scale infrastructures, X-omics (184.034.019). The UK Medical Research Council and Wellcome (Grant Ref: 102215/2/13/2) and the University of Bristol provide core support for ALSPAC. A comprehensive list of grants funding is available on the ALSPAC website (http://www.bristol.ac.uk/alspac/external/documents/grantacknowledgements.pdf). This research was specifically funded by the BBSRC (grant numbers BBI025751/1 and BB/I025263/1). M.S., C.R. and D.C. are funded by the MRC (Grant Numbers MC_UU_00011/5 and MC_UU_00011/1). GWAS data was generated by Sample Logistics and Genotyping Facilities at Wellcome Sanger Institute and LabCorp (Laboratory Corporation of America) using support from 23andMe. The NTR received funding from the Netherlands Organization for Scientific Research (NWO): Biobanking and Biomolecular Research Infrastructure (BBMRI\u2013NL, 184.021.007; 184.033.111) and Netherlands Twin Registry Repository NWO 480-15-001/674. This work was also supported by \u201CAggression in Children: Unraveling gene-environment interplay to inform Treatment and InterventiON strategies\u201D project (ACTION). ACTION received funding from the European Union Seventh Framework Program (FP7/2007-2013) under Grant Agreement No. 602768. SEM is supported by NHMRC Investigator Grant APP1172917. The funders had no role in study design, data collection and analysis, decision to publish or preparation of the manuscript we are extremely grateful to all the families who took part in this study, the midwives for their help in recruiting them, and the whole NTR and ALSPAC teams, which includes interviewers, computer and laboratory technicians, clerical workers, research scientists, volunteers, managers, receptionists and nurses.

N2 - Handedness has low heritability and epigenetic mechanisms have been proposed as an etiological mechanism. To examine this hypothesis, we performed an epigenome-wide association study of left-handedness. In a meta-analysis of 3914 adults of whole-blood DNA methylation, we observed that CpG sites located in proximity of handedness-associated genetic variants were more strongly associated with left-handedness than other CpG sites (P = 0.04), but did not identify any differentially methylated positions. In longitudinal analyses of DNA methylation in peripheral blood and buccal cells from children (N = 1737), we observed moderately stable associations across age (correlation range [0.355–0.578]), but inconsistent across tissues (correlation range [- 0.384 to 0.318]). We conclude that DNA methylation in peripheral tissues captures little of the variance in handedness. Future investigations should consider other more targeted sources of tissue, such as the brain.
