Researchers at the University of Pittsburgh and KU Leuven have discovered a suite of genes that influence head shape in humans. These findings, published this week in Nature Communications, help explain the diversity of human head shapes and may also offer important clues about the genetic basis of conditions that affect the skull, such as craniosynostosis.
By analyzing measurements of the cranial vault —the part of the skull that forms the rounded top of the head and protects the brain—the team identified 30 regions of the genome associated with different aspects of head shape, 29 of which have not been reported previously.
“Anthropologists have speculated and debated the genetics of cranial vault shape since the early 20th century,” said co-senior author Seth Weinberg, Ph.D., professor of oral and craniofacial sciences in the Pitt School of Dental Medicine and co-director of the Center for Craniofacial and Dental Genetics.
