AimMurine double minute clone 2 (MDM2) is an important regulator of p53 tumor suppressor protein. Because increased MDM2 expression has been observed in different tumors, its polymorphisms are proposed to be associated with accelerated tumor formation. The aim of this study was to examine the association between T309G (rs2279744) and 40-bp Insertion/deletion (rs3730485) polymorphisms of the MDM2 gene and risk of uterine leiomyoma (UL).
MethodsWe analyzed the MDM2 gene polymorphisms of 154 UL patients and 197 healthy controls by polymerase chain reaction (PCR) or PCR restriction fragment length polymorphism (RFLP) methods.
ResultsThe frequency of MDM2T309G polymorphism genotypes was not different between UL women and controls. Although there was an association between MDM2 40-bp del/del genotype and UL before and after adjustment for age, the association between Insertion/deletion (Indel) genotype and UL was significant after adjustment for age.
ConclusionMDM2T309G polymorphism was not associated with UL and MDM2 40-bp Indel polymorphism could be an age-related risk factor for UL.
