Genetics and DNA Prediction of Appearance

Department Genetic Identification

Understanding the genetic basis of human appearance is of fundamental scientific importance, has medical relevance, and allows practical applications such as in forensics and anthropology. For instance, appearance prediction from DNA found at crime scenes allows the reconstruction of how a suspect looks like, providing useful information to find unknown perpetrators of crime not identifiable with current forensic DNA profiling. Moreover, appearance traits are involved in disease manifestation linking appearance genetics with medical genetics. Therefore, we are unveiling the genetic basis of various human appearance traits. From the genes we find, we identify the most trait predictive DNA markers, and use them to develop and validate genetic tools and statistical models for predicting appearance from DNA for applications in forensics or anthropology. For instance, our pioneering work on developing DNA test systems for eye and hair colour prediction incited the establishment of a new subfield within forensic genetics referred to as Forensic DNA Phenotyping. Moreover, we are investigating via functional genetic techniques why the identified DNA markers are associated with, and predictive for, appearance traits. We are also genetically linking appearance with disease such as for various skin phenotypes, and are exploring the genetic basis of appearance traits that change with age.
