Reconstr. 18, 549555. J. Similarly, the naso-labial angle will be associated with nose prominence and DCHS2 is linked to both traits. International anthropometric study of facial morphology in various ethnic groups/races. Impressions of an individuals health are integral to social interactions and judgments are made on the visual appearance of skin, degree of roundness of the face and facial expression (Henderson et al., 2016). Do mens faces really signal heritable immunocompetence? It only takes an hour to cross the Irish Sea from Scotland - but sometimes it can feel like you're on the other side of the world. J. Hum. In cleft lip tissue, limited evidence was found for an association between LINE-1 methylation and maternal exposures but conclusions were limited by modest sample sizes (Khan et al., 2018). (2016). Res. Arch. New perspectives on craniofacial growth. Int. There's also some more darker features in some people, like black hair and brown eyes. Increasing the sample sizes of genetic studies of facial morphology through international collaborations, such as the type II diabetes consortia DIAGRAM (Morris et al., 2012), will help to improve the understanding of genetic associations and shared influences on facial traits (Evans, 2018). (2014). Nat. Table 2 highlights that genetic variants influencing facial morphology can have pleiotropic effects on parts of the body independent to the brain and surrounding craniofacial structures (e.g., cardiovascular, endocrine, gastro-intestinal, central nervous, musculo-skeletal and uro-genital systems). doi: 10.1371/journal.pone.0093442, Lange, S., Shield, K., Koren, G., Rehm, J., and Popova, S. (2014). Strong levels of phenotypic and genotypic spousal assortment have been previously demonstrated for height (Robinson et al., 2017) and similar methods could be applied using facial phenotypes to explore the influences of facial morphology on mate choice. 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). A general model of dioxin contamination in breast milk: results from a study on 94 women from the Caserta and Naples areas in Italy. empire medical training membership. Homo 61, 191203. These are interesting answers. I am not sure if I can add anything or not, but I think there are a couple of areas that should be addressed. First, doi: 10.1038/nrg3706. Identification of 15 loci influencing height in a Korean population. Hum. doi: 10.1038/ng.2383, Mossey, P. A., Little, J., Munger, R. G., Dixon, M. J., and Shaw, W. C. (2009). 132, 771781. 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). Sharman, N. (2011). Genet. Natl. There have been nine GWAS studies and it is appropriate to try and integrate their findings through a meta-analysis. Celt (people doi: 10.1016/j.toxrep.2015.05.011, Mitchem, D. G., Purkey, A. M., Grebe, N. M., Carey, G., Garver-Apgar, C. E., Bates, T. C., et al.
