Mutations in LRP5 and BMP4 are associated with mesiodens, tooth agenesis, root malformation, and oral exostoses. | LitMetric

AI Article Synopsis

  • WNT/β-catenin and BMP signaling pathways are crucial for tooth development, and their dysregulation can lead to dental anomalies in humans.
  • Researchers identified LRP5 and BMP4 gene mutations in patients with isolated dental anomalies, such as tooth agenesis and root malformation.
  • This study presents the novel finding that LRP5 mutations are linked to specific dental issues, suggesting a communication between WNT/β-catenin and BMP pathways in tooth development.

Article Abstract

WNT/β-catenin and BMP signaling pathways play important roles in the process of tooth development. Dysregulation of WNT/β-catenin and BMP signaling is implicated in a number of human malformations, including dental anomalies. Whole exome and Sanger sequencing identified seven patients with LRP5 mutations (p.Asn1121Asp, p.Asp856Asn, p.Val1433Met, and p.Val1245Met) and six patients with BMP4 mutations (p.Asn150Lys, p.Gly168Arg, p.Arg269Gln, and p.Ala42Glu). All patients were affected with isolated dental anomalies (dental anomalies with no other structural defects), including mesiodens, tooth agenesis, unseparated roots, narrow roots, shortened and tapered roots, and taurodontism. Five patients with LRP5 and one with BMP4 mutations had oral exostoses. Protein models of LRP5 mutations indicate the possible functional effects of the mutations. Here we report for the first time that mutations in LRP5 are associated with dental anomalies. LRP5 appears to be the first gene related to pathogenesis of mesiodens. We also show for the first time that in addition to tooth agenesis, mutations in BMP4 are also implicated in root maldevelopment and torus mandibularis. Sharing of the phenotypes of the patients with LRP5 and BMP4 mutations, which include root maldevelopment, tooth agenesis, and torus mandibularis, implicates cross talks between the WNT/β-catenin and BMP signaling pathways, especially during root development.
