Association Of Eda Gene Polymorphisms Rs 372024, Rs 3764746, Rs 3795170 In Skeletal Class I Cases With Dental Crowding

ABSTRACT

The EDA gene, associated with X linked hydrotic form of Ectodermal Dysplasia, its mutations could potentially lead to differential gene expression that causes large tooth phenotype, which has been suggested to cause dental crowding. We analyzed the association of genetic polymorphisms in EDA gene variants rs 372024, rs 3764746, and rs 3795170 among Skeletal Class I crowding cases using blood samples of 30 cases and 30 controls, which were subjected to PCR amplication and DNA sequencing. Based on the statistical analysis using the Z test we found CG and GG genotype for rs3764746 and GT and TT genotype for rs3795170 showed a statistically signicant result. These results suggest that EDA gene variants rs3764746 and rs3795170 could be genetic markers for dental crowding in our population while EDA gene variant rs372024 did not show any signicant association in our population. These ndings can provide in-depth knowledge, regarding the genetic inuences on the incidence of crowding of teeth.
