Genetic Link Identified Between Face and Brain Shape by Hannah Joy on April 5, 2021 at 10:35 PM
About 76 overlapping genetic locations have been identified that shape both our face and brain, reveals an interdisciplinary team led by KU Leuven and Stanford.
What the researchers didn t find is evidence that this genetic overlap also predicts someone s behavioral-cognitive traits or risk of conditions such as Alzheimer s disease. This means that the findings help to debunk several persistent pseudoscientific claims about what our face reveals about us.
There were already indications of a genetic link between the shape of our face and that of our brain, says Professor Peter Claes from the Laboratory for Imaging Genetics at KU Leuven, who is the joint senior author of the study with Professor Joanna Wysocka from the Stanford University School of Medicine.

But our knowledge on this link was based on model organism research and clinical knowledge of extremely rare conditions, Claes continues. We set out to map the genetic link between individuals face and brain shape much more broadly,

What is neuroscience? Neuroscience is the scientific study of nervous systems. Neuroscience can involve research from many branches of science including those involving neurology, brain science, neurobiology, psychology, computer science, artificial intelligence, statistics, prosthetics, neuroimaging, engineering, medicine, physics, mathematics, pharmacology, electrophysiology, biology, robotics and technology. – What is neurology? – Definition of neurology: a science involved in the study of the nervous systems, especially of the diseases and disorders affecting them. – Neurology research can include information involving brain research, neurological disorders, medicine, brain cancer, peripheral nervous systems, central nervous systems, nerve damage, brain tumors, seizures, neurosurgery, electrophysiology, BMI, brain injuries, paralysis and spinal cord treatments.
Genetics of human face begin to reveal underlying profile
Using 3-D facial images with over 7,000 data points, researchers have identified changes in the DNA sequence of European individuals that contribute to variation in facial features. These findings help us better understand human variation and facial birth defects.

Genetics of human face begin to reveal underlying profile

UNIVERSITY PARK, Pa. The genetics behind the shape of the human face are difficult to decipher, but now an international team of researchers has connected specific genetic signals with specific areas of the face. They not only can see the signals of normal facial features in the genome, but also hope their work can shed light on craniofacial malformations such as cleft lip and palate.
