Most of my projects involve genetic research with human samples in order to study congenital dental/craniofacial problems. We are continuing the recruitment of new patients with non-syndromic tooth agenesis for our tooth agenesis study. A candidate gene approach is used to detect new mutations in known tooth agenesis genes and new causative genes in these patients. The list of candidate genes for this study includes PAX9, MSX1, AXIN2, DLX1, DLX2, LEF1, GLI2, GLI3, PITX2, LHX6, BARX1, MSX2, ACTVIN-beta A, and EDA1. Drs. Chalothorn and Beeman in Kentucky found a higher prevalance of mild tooth agenesis in ovarian cancer/cyst patients and asked us to do an ovarian cancer/tooth agenesis association study with their samples. We investigated buccal swab samples from these patients for mutations/polymorphisms in the major known tooth agenesis genes PAX9, MSX1, AXIN2 and in the homeo-domain proteins BARX1 and BARX2, both of which play a role in the development of craniofacial structures as well as tumors. We have found that a common polymorphism in MSX1 is found more frequently in affected individuals and that there are several new polymorphisms in the BARX genes; some must be investigated for pathogenic potential. We have also found one mutation in the AXIN2 gene that could contribute to ovarian cancer development and one EDA mutation that probably causes the tooth agenesis in the affected patient.
The clinical objectives (a and b below) of our EDA-gene mutations in non-syndromic tooth agenesis project are to provide the dental practitioner with guidelines for the referral of tooth agenesis patients to geneticists because EDA-associated selective tooth agenesis may be curable in the near future by post-natal injection of recombinant EDA protein. For this project, we plan the:
a. Determination of the prevalence of EDA-gene mutations in selective tooth agenesis;
b. Dental phenotype characterization of EDA-associated selective tooth agenesis;
c. Biochemical characterization of the molecular malfunction of mutated EDA protaions (in collaboration with Dr. Pascal Schneider, Lausanne, Switzerland).
Two studies are being conducted in collaboration with Dr. Hitesh Kapadia: 1) Pierre Robin Study. We have collected buccal swab samples from 33 patients with the Pierre Robin syndrome. The HAND1 and HAND2 genes, as well as the branchial arch enhancer elements in in the HAND2 gene, are screened for mutations. Twenty-nine samples have been analyazed to date (some only partially), and one definitive mutation in HAND2 has been identified; 2) Functional Analysis of the PAX9 Gene. This project investigates the capability of wild-type and mutant PAX9 proteins to bind certain promoters and activate the transcription of target genes. Protein-protein interactions between PAX9 and other homeo box partner genes such as MSX1 and 2 are also studied in order to increase our understanding of tooth development.
