The maternal environment is thought to play an important role with regards to orofacial clefts. These transcriptional factors may be limited to detail the precise facial shape or can be quickly activated in rapid periods of growth and development. J. Orthod. Sci. Orthod. (2014b).

In addition, anthropometric masks have been proposed whereby five landmarks are used to crudely orientate the 3D facial shells which are then non-rigidly mapped on to a template which generates about 10,000 quasi landmarks (Claes et al., 2012).

There was also greater asymmetry in the nsCL/P group (LEFTY1, LEFTY2, and SNAI1) (Miller et al., 2014). Commun. Twin studies have indicated that facial shape is mainly due to genetic influences (75%) although the percentage variance explained in GWAS studies is extremely low generally explaining less than 2% of the total variance.

Historically, craniofacial genetic research has understandably focused on identifying the causes of craniofacial anomalies and it has only been within the last 10 years, that there has been a drive to detail the biological basis of normal-range facial variation.

Indeed, previous studies have demonstrated that self-perceived and genetically inferred ancestry are associated with facial morphology, particularly with regards to the shape of the nose (Dawei et al., 1997; Le et al., 2002; Farkas et al., 2005; Claes et al., 2014). 44, 981990.

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).
