Reconstr. (2012). There has been significant progress in the first 6 years of GWAS and facial genetics. Sci. 22, e1e4. The availability of summary statistics on large GWAS studies will also enable the application of quantitative genetics methods to further investigate the genetic architecture of facial morphology. BMJ Open 5:e009027. 171, 771780.

However, it is important to note that stochastic chance events such as facial trauma, infections, burns, tumors, irradiation and surgical procedures can all have a significant impact on facial development and consequently facial morphology. Genet. A quantitative genetic study of cephalometric variables in twins. 23, 764773. Irish & Scottish Culture Differences (With Diane Jennings) Med. There was reduced facial convexity (SNAI1), obtuse nasolabial angles, more protrusive chins (SNAI1, IRF6, MSX1, MAFB), increased lower facial heights (SNAI1), thinner and more retrusive lips and more protrusive foreheads (ABCA4-ARHGAP29, MAFB) in the nsCL/P relatives compared to controls. Similarly, epigenetic processes may mediate the effects of germline genetic variation. GWAS studies coupled with high-resolution three-dimensional imaging of the face have enabled the study of the spatial relationship of facial landmarks in great detail. Genet. A. (2010). Prevention may be challenging (other than continually improving environmental conditions and reducing exposure to potential epigenetic factors) as facial development occurs very early in gestation during a period whereby the mother is often unaware she is pregnant.

Non-syndromic cleft lip/palate (nsCL/P) is a birth defect with a complex etiology, primarily affecting the upper lip and palate (Mossey et al., 2009; Dixon et al., 2011).

Previous studies have suggested that facial features such as attractiveness (Little et al., 2001; Fink and Penton-Voak, 2002), hair color (Wilde et al., 2014; Adhikari et al., 2016; Field et al., 2016; Hysi et al., 2018), eye color (Little et al., 2003; Wilde et al., 2014; Field et al., 2016) and skin pigmentation (Jablonski and Chaplin, 2000, 2010; Wilde et al., 2014; Field et al., 2016) may influence mate choice and/or have been under historical selection. Aesthetic. (2018). Genet. Historical migrations, such as the European colonization of Latin America, led to genetic admixture (breeding between individuals from previously isolated populations) (Hellenthal et al., 2014), which greatly influenced the facial morphology of the Latin American population. 39, 57106. Specific facial features which were taken into account by the software included nose width and length, lip thickness and hairline. Forensic Sci. Facial shape and features are the result of mutations, genetic drift, recombination and natural selection. 227, 474486. These transcriptional factors may be limited to detail the precise facial shape or can be quickly activated in rapid periods of growth and development. Surg.

Facial morphological differences relating to ancestry are well-characterized when comparing individuals from distinct populations, but distinct differences remain even within more ancestrally homogeneous populations. A novel strategy for forensic age prediction by DNA methylation and support vector regression model. Indeed, a previous study demonstrated that a major risk locus for non-syndromic cleft lip/palate (nsCL/P), in a non-coding interval, is involved in the regulation of gene expression in the developing murine face (Uslu et al., 2014) while another study found some evidence that nsCL/P genetic variants may influence nsCL/P risk via changes in DNA methylation and gene expression (Howe et al., 2018b). doi: 10.1002/ajmg.a.20249, Miller, S.

It is therefore important to use causal inference techniques such as epigenetic Mendelian randomization Relton and Davey Smith, 2012) or the Steiger test (Hemani et al., 2017) to orientate the likely directions of effect between phenotypes, epigenetic modifications and gene expression. Orbicularis oris muscle defects as an expanded phenotypic feature in nonsyndromic cleft lip with or without cleft palate. Heritability maps of human face morphology through large-scale automated three-dimensional phenotyping. Genet. For example, significantly more women self-report having blonde and red hair while more men as self-report as having black hair (Hysi et al., 2018). Key transcriptional factors (activators or repressors) have been identified indicating extensive activation during early craniofacial development. There have been nine GWAS studies and it is appropriate to try and integrate their findings through a meta-analysis. 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).
