Association between rs11001553 of DKK1 and non-syndromic tooth agenesis in the Chinese Han population
Tooth agenesis is one of the most common anomalies of human dentition. Recent genetic studies have provided information regarding a number of genes related to both syndromic and non-syndromic forms of hypodontia. In a previous study, we found that polymorphism in rs11001553 of DKK1 was associated with hypodontia in the Chinese Han population. In this study, we extended this investigation to 89 individuals diagnosed with sporadic non-syndromic oligodontia (40 males and 49 females).
