A constellation of dental anomalies in a chromosomal deletion syndrome (7q32): case report.

A case is reported of a patient with deletion of the long arm of chromosome 7 at a highly specific locus (7q32). In addition to significant craniofacial stigmata and global developmental delay, the patient presented with numerous clinical and radiographic dental anomalies observed over a 10-year period. Hypodontia, accessory roots, dens invaginatus, hypoplastic enamel, and numerous pulpal anomalies all were noted. Some of these dental findings suggest trichodentoosseous syndrome (TDO), although the other stigmata do not. The wide variety of dental findings in this patient may help to define the role of chromosome 7q32 in dental development.
