The Face and Age. (2018). - Understanding the etiology of craniofacial anomalies; e.g., unaffected family members of individuals with non-syndromic cleft lip/palate (nsCL/P) have been shown to differ in terms of normal-range facial variation to the general population suggesting an etiological link between facial morphology and nsCL/P. doi: 10.1002/ajhb.21208, Jelenkovic, A., Poveda, A., Susanne, C., and Rebato, E.

H., van Karnebeek, C. D., Caron, H. N., and Hennekam, R. C. (2003). 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). Over time, facial morphology across populations has been influenced by various factors, such as migration, mate-choice, survival and climate, which have contributed to variation in facial phenotypes. Genet. This includes high cheekbones, a bent nose, reddish brown skin tone and coarse, dark hair. Am. Richmond, S., Wilson-Nagrani, C., Zhurov, A. I., Farnell, D., Galloway, J., Mohd Ali, A.

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. Hum. Forensic Sci. (2016).

Hu, D., and Helms, J. Lets face itcomplex traits are just not that simple. The craniofacial region is made up of a series of complex structures which contribute to overall facial shape. A previous study tested this hypothesis using 3D facial images and genetic variation in the major histocompatibility complex (MHC) region and found weak evidence to support this (Zaidi et al., 2018).

Scottish tartans are a representation of a Scottish clan, and each Scottish family has their own tartan, distinguished by their surname. Key transcriptional factors (activators or repressors) have been identified indicating extensive activation during early craniofacial development. Many of the previously discussed genetic variants associated with facial traits in GWAS reside in non-protein coding regions of the genome with unclear functional relevance. Bioessays 29, 145154. - Many factors such as ancestry, sex, eye/hair color as well as distinctive facial features (such as, shape of the chin, cheeks, eyes, forehead, lips, and nose) can be identified or estimated using an individuals genetic data, with potential applications in healthcare and forensics. doi: 10.1371/journal.pone.0118355, Paternoster, L., Zhurov, A.

This association suggests that developmental processes relating to normal-variation in philtrum development are also etiologically relevant to nsCL/P, highlighting the shared genetic influences on normal-range facial variation and a cranio-facial anomaly (Howe et al., 2018a). WebYou may have porcelain, pale skin, or you may have freckles that outnumber the days of the year, but your features will be pleasantly proportioned and your eyes bright, with a genuine smile that lights up your face.

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.

Scottish people are an amalgamation of people of Celtic, Gael, Pict and Brython descent. Contrastingly, previous estimates suggest that antero-posterior face height, mandibular body length, ramus height, upper vermillion height, nasal width and maxillary protrusion are more strongly influenced by environmental factors (Jelenkovic et al., 2010; Djordjevic et al., 2016; Sidlauskas et al., 2016; Cole et al., 2017; Tsagkrasoulis et al., 2017). eds G.
