Abstract

Objective: Variations in genes that are critical for tooth formation may contribute to the tooth agenesis. MMPs are potential candidate genes for dental alterations based on the roles they play during embryogenesis. The aim of this study was to investigate the possible association between MMP1, MMP3, and MMP20 and tooth agenesis. Methods: One hundred sixty-seven nuclear families from two different populations were analysed, 116 from Brazil and 51 from Turkey. Probands had at least one congenitally missing tooth. DNA samples were obtained from blood or saliva samples and genotyping was performed using TagMan chemistry. In addition, Mmp20 was selected for quantitative real-time polymerase chain reaction analysis with SYBR Green I Dye in mouse tooth development. Results: Associations between tooth agenesis and MMP1 (p = 0.007), and MMP20 (p = 0.03) were found in Brazilian families. In the total dataset, MMP20 continued to be associated with tooth agenesis (p = 0.01). Mmp20 was not expressed during the initial stages of tooth development. Conclusion: Our findings provide evidence that MMP1 and MMP20 play a role in human tooth agenesis. (C) 2010 Elsevier Ltd. All rights reserved. (AU)
