A variant of TP53 gene (rs 1625895, 13494g>A) is associated with neoplasm localization in patients with uterine leiomyoma

Abstract

Summary. Background: Uterine leiomyoma (UL) is the most common benign neoplasm of the uterus. It is still unknown surely what exactly initiates transformation of the uterine myometrial cells into UL. Aim: To study the effect of the TP53 gene variants on the risk of development and clinical features of UL. Materials and Methods: Case-control study was performed using molecular genetic analyses of variants rs1042522 (119 G>C) and rs1625895 (13494G>A) of TP53 gene in patients with UL and comparison group of healthy women. Results: Investigated TP53 gene variants were not associated with the risk of UL development. The patients with the 13494GG genotype (rs1625895) had significantly more often subserous UL (р < 0.05). In patients with heterozygous variant of TP53 — 13494GA genotype (rs1625895) intramural UL was observed (р < 0.05). Conclusions: The rs1625895 (13494G>A) variant of TP53 gene was associated with UL localization. The identified dependence of the UL localization on the TP53 gene variant could be useful for personalized approach to treatment.
