Face genes identified

Washington, September 14 (ANI): In a new study, researchers have found five face genes that determine human facial shapes.

Monozygotic twins have almost identical faces and siblings usually have more similar faces than unrelated people, implying that genes play a major role in the appearance of the human face.

However, almost nothing is known about the genes responsible for facial morphology in humans.

This new study, carried out on behalf of the International Visible Trait Genetics (VisiGen) Consortium, used head magnetic resonance images together with portrait photographs to map facial landmarks, from which facial distances were estimated.

The researchers then applied a genome-wide association (GWA) approach, with independent replication, to finding DNA variants involved in facial shapes in almost 10,000 individuals.

Three of the five genes identified have been implicated previously by other approaches in vertebrate craniofacial development and disease; of these three, one was reported to be involved in facial morphology in a GWA study on children published earlier this year.

The remaining two genes potentially represent completely new players in the molecular networks governing facial development.

"These are exciting first results that mark the beginning of the genetic understanding of human facial morphology," Professor Manfred Kayser, lead author of the study from the Erasmus University Medical Center, Rotterdam, The Netherlands, said.

"Perhaps some time it will be possible to draw a phantom portrait of a person solely from his or her DNA left behind, which provides interesting applications such as in forensics. We already can predict from DNA certain eye and hair colours with quite high accuracies," Kayser added.

The study has been published in PLOS Genetics. (ANI)
