OBJECTIVE
Improving the effectiveness of early diagnosis and prediction of the risk of development and recurrence of uterine leiomyoma by searching for genetic markers of the development of this disease.
MATERIAL AND METHODS
Patients underwent hysterectomy or myomectomy for symptomatic uterine myoma. Individual fibroids and blood of all patients were collected during the surgery. DNA extraction and genotyping of six loci (rs3020434, rs11742635, rs124577644, rs12637801, rs2861221, rs17677069) of the ESR1, FBN2, CELF4, KCWMB2 genes for research the candidate genes.
MEASUREMENTS AND MAIN RESULTS
We analyzed a group of patients with a family history of UL and a control group without uterine myomas and a familial predisposition to this pathology. Six significant single nucleotide polymorphisms (SNPs) were selected for PCR-genotyping of a large data set of patients with UL. All investigated loci (rs3020434, rs11742635, rs124577644, rs12637801, rs2861221, rs17677069) demonstrated the lower frequency of minor alleles within a group of women with UL, especially in a subgroup consisting of patients with UL and a family history of leiomyomata. We also found that minor allele frequency of these SNPs in our control group was higher than among Caucasian population.
CONCLUSION
Obtained results clearly demonstrated the role of inheritance in the process of developing UL. Rare alleles of all six investigated polymorphisms were significantly often detected in a control group consisting of postmenopausal women without UL and women with a family history of this pathology. We assumed that as a result of the study, a specific SNP panel will be developed that will allow us to assess the risk of development and recurrence of uterine leiomyoma.
