Abstract

Aim. To study the spectrum of variants in the PRL, PRLR, PRLHR genes in women of reproductive age with non-tumor hyperprolactinemia. Material and methods. In women with non-tumor hyperprolactinemia (n = 15), targeted high-throughput sequencing of the PRL, PRLR, and PRLHR genes was performed. The target panel of genes included coding regions and adjacent splicing sites. Results. When analyzing the PRL, PRLR, PRLHR genes, a number of rare and common variants were identified. The common variant rs1205955 was found in the PRL gene (MAF А = 0.279). For the PRLR gene, a rare variant rs185353023 was identified in the 3’UTR (MAF А/С = 0.003) and 12 common variants. For the PRLHR gene, 10 common variants have been identified. The maximum number of variants was localized in the 3’UTR region and introns. Conclusions. For the first time in Russia, targeted high-throughput sequencing of the PRL, PRLR, PRLHR genes was performed, the results of which did not reveal obvious pathological variants in the studied genes in women with high prolactin content of non-tumor origin. The discovered polymorphism in these genes makes it possible to further study its association with impaired function of the prolactin link of hormonal regulation.
