The importance of assessing nucleotide polymorphisms of the <i>tp53</i> signaling pathway genes in uterine infertility factor diagnosis

Abstract

INTRODUCTION: The WHO reported a 30% frequency of female infertility, which does not tend to decrease. Concurrently, the uterine factor occupies one of the most important places in infertility structure, reaching 50%. Improvement of assisted reproductive technology methods can successfully overcome many causes of infertility, but the possibilities of the method are limited in the uterine factor of infertility.&#x0D; AIM: To assess the presence of nucleotide polymorphisms of the TP53 signaling pathway genes (LIF rs41281637, c.256GA; LIF rs929271, n.397-2854TG; MDM2 rs2279744, c.14+309TG; MDM4 rs1563828, c.558+572AG; TP53 rs1042522, c.215CG) in the endometrium in patients with primary and secondary infertility.&#x0D; MATERIALS AND METHODS: In 20182021, the V.F. Snegirev Clinic of Obstetrics and Gynecology examined and treated 54 patients aged 26 to 48 years with primary or secondary infertility, including a genetic endometrial sample examination. The first group consisted of 28 patients with primary infertility aged 26 to 42 years. The 2nd group included 26 patients aged 29 to 48 years with secondary infertility.&#x0D; RESULTS: The study evaluated the expression of nucleotide polymorphisms of the TP53 signaling pathway genes in patients with primary and secondary infertility. Study results, data were obtained indicating various variants of nucleotide polymorphisms LIF, MDM2, MDM4, and TP53 in primary and secondary infertility, as well as the identity of a marker, such as LIF rs41281637 (G/A) in patients of both groups.&#x0D; CONCLUSION: The experimental data obtained indicate an important contribution of genetic polymorphisms in the genes of the TP53, LIF and MDM4 signaling pathway to the development of primary and MDM2 secondary infertility in women.
