The aim of this retrospective observational study is to investigate the association between genotype and craniofacial phenotype in orthodontic patients affected by Marfan and Loeys-Dietz syndromes. A total of 39 patients aged between 4 and 18 years were enrolled and stratified into four groups according to the underlying pathogenic genetic variants. Lateral cephalometric radiographs were analyzed to assess sagittal, vertical, and cranial base skeletal relationships. Each patient group was compared with age- and sex-matched controls, as well as between syndromes and among Marfan subgroups. Statistical analyses were performed to evaluate differences in craniofacial parameters and to explore potential genotype-phenotype correlations relevant for orthodontic diagnosis.
