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.

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). doi: 10.1136/bmjopen-2016-015410, Marazita, M.

Post-natally, facial growth tends to follow general somatic growth with periods of steady increments in size interspersed with periods of rapid growth with the peak growth occurring at puberty (Tanner et al., 1966a,b; Bhatia et al., 1979; Kau and Richmond, 2008; Richmond et al., 2009; Richmond S. et al., 2018). 22, e1e4.

The modifiable nature of epigenetic processes has led to much excitement that these processes may mediate the effect of environmental exposures. Scientists have merged dozens of famous faces to create what they call the most beautiful faces in the world. It has been hypothesized that deleterious coding variants may directly cause congenital anomalies while non-coding variants in the same genes influence normal-range facial variation via gene expression pathways (Shaffer et al., 2017; Freund et al., 2018). Reliability of measuring facial morphology with a 3-dimensional laser scanning system. With increased sample sizes, improved understanding of shared genetic influences on human traits and advancement in techniques there is likely to be significant further progress in the next 6 years. Focusing on specific phenotypes and genetic variants in families will identify additional rare variants should be followed-up with a combination of genotyping and deep re-sequencing of the variants or genes of interest in large numbers of cases and controls.

Similarly, genetic variations associated with normal-range facial differences have been linked to genes involved in Mendelian syndromes such as TBX15 (Cousin syndrome) (Shaffer et al., 2017; Claes et al., 2018), PAX1 (Otofaciocervical syndrome) (Shaffer et al., 2016) and PAX3 (Waardenburg syndrome) (Paternoster et al., 2012). While each person is unique, people of Scottish descent are generally average or tall in stature and have a thin build. WebThese are the major differences between an Irish and a Scottish accent.

Molecular studies have shown that the growth, structure and patternation of the facial primordia is controlled by a series of complex interactions that involves many factors such as fibroblast growth factors, sonic hedgehog proteins, bone morphogenetic proteins, homeobox genes Barx1 and Msx1, the distal-less homeobox (Dlx) genes, and local retinoic acid gradients (Barlow et al., 1999; Hu and Helms, 1999; Lee et al., 2001; Ashique et al., 2002; Mossey et al., 2009; Marcucio et al., 2015; Parsons et al., 2015).
