The human skull, a complex structure that protects the brain. The question lies on what genetic factor dictates cranial morphology? New shocking evidence was found by researchers at the University of Pittsburgh and KU Leuven that 30 regions of the genome are associated with the shape and structure of the brain. More importantly, 29 of these are new findings that weren't reported prior. Prior research of genes flourished results in rare human conditions. However, lack of awareness was shown on the genetic basis for typical features of the general public. This awareness will produce enrich results. In addition, the following suggestions paleoanthropology studies, implementing different measures to describe vault shape, and variants in gene association.
Among the following suggestions, variants in gene association sheds light on the bigger picture. A discovery of the strong association near genes can dictate different results in formation of the head and skull. This relates to two variants near the gene RUNX2 that could coordinate development of the bone structure of the skull, or having global effects of the cranial vault. Another aspect is three variants BMP2, BBS9 and ZIC2 corresponding to Craniosynostosis. These variants suggest genes could aid in the development.
Overall, the human skull is a complex structure. It's clear that unlocking the human genome is a trip down the rabbit hole. As new technologies and methods immerse, more luck in understanding the secrets to be found within the genome that impact the cranial vault.

Genetics and Human Cranial Vault Shape: A Reevaluation

New Study Reveals the Genetics of Human Head Shape
This study analyzed measurements of the cranial vault, the part of the skull that encases and protects the brain and forms the rounded top of the head, in over 6,000 adolescents and identified 30 genomic regions associated with different head shapes. 29 of the 30 genomic regions were previously unreported. Researchers used magnetic resonance scans in order to get 3D surfaces/images of the cranial vault. They then divided the 3D vault surfaces into smaller subparts and quantified the shape of those subparts and tested millions of genetic variants to measure the vault shape.
Strong associations were found near genes that play key roles in the formation of head and face shape and bone development. Variants near the gene RUNX2, for example, were associated with vault shape. Unlike the RUNX2 gene, there are other genes that have a more localized effect on the cranial vault. Despite the research being conducted on healthy participants, the finding may be applicable to those with a skull condition as it may help uncover the biological basis of the disease. The researchers found that variants near the genes BMP2, BBS9, and ZIC2 were associated with craniosynostosis. This suggests that these genes could play a role in the development of craniosynostosis, which could allow for a more in-depth understanding of the process and treatment for this condition. These findings are important as they could be applied to future paleoanthropology studies which could uncover information about the early development of modern humans. It is interesting to see the benefits of this study for not only understanding the past but also for the future. These findings could hopefully offer more clues about conditions and diseases that involve the cranial vault, like craniosynostosis, and help develop more efficient and less invasive treatments for such conditions.
