Dental findings in SGMRT1 are described by OMIM as “delayed primary tooth exfoliation and permanent tooth eruption, truncated tooth root formation, early-onset periodontal disease, and severe root and alveolar bone resorption associated with dysregulated mineralization, leading to tooth loss” (SGMRT1, OMIM: 182250). This evidence concerns the gene IFIH1 and periodontal disorder.
