Similarly, it has been hypothesized that maternal smoking may influence facial morphology and be a risk factor for cleft lip and palate (Xuan et al., 2016) with DNA methylation a possible mediator (Armstrong et al., 2016). Maternal smoking during pregnancy is associated with mitochondrial DNA methylation. Genet. Genet. (2010).

The gene regulatory systems are complex and numerous and detailing these regulatory mechanisms has been the goal of the NIH Roadmap Epigenomics Project whereby next generation sequencing technologies (e.g., ChiP seq) are employed to map DNA methylation, histone modifications, chromatin accessibility in a variety of research media such as, animal models (mouse, chicken, zebrafish, frog, and primates) and stem cells and regulated human fetal tissues (Hochheiser et al., 2011; Roosenboom et al., 2016; Van Otterloo et al., 2016). Variations of this toast include slinte mhaith "good health" in Irish ( mhaith being the lenited form of maith "good"). The term Gaelic, as a language, applies only to the language of Scotland. There have been nine GWAS studies and it is appropriate to try and integrate their findings through a meta-analysis.
