The association of EGF rs2237051 variant, serum EGF levels and generalized aggressive periodontitis: a preliminary study.

We demonstrated that EGF rs2237051 variant and the increased level of serum EGF were associated with the risk of GAgP, the serum EGF was up-regulated in patients with GAgP. It was indicated that serum EGF might be a biomarker of GAgP and EGF rs2237051 may be related to the genetic background of GAgP.
