Isolated cranial shape variation; syndromic forms with craniosynostosis are caused by identifiable gene mutations.
How Genetic Is Brachycephaly?
Genetics plays a meaningful role in Brachycephaly, with heritability estimated at around 50%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Brachycephaly: FGFR2 FGFR3 TWIST1. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
