Deciphering the Role of Calcium Signaling Pathway‐Associated Single Nucleotide Variants in Susceptibility to Hypertension

Résumé fourni par la source

BACKGROUND: As a complex disease, hypertension (HTN) is influenced by both genetic and environmental factors and their interaction. The calcium signaling pathway is known to be involved in the regulation of blood pressure, and dysfunction in this pathway may contribute to the development of hypertension. Genome-wide association studies (GWAS) have identified several genes in the calcium signaling pathway associated with susceptibility to HTN, including PLCB1, ATP2B1, and ADRB1. The aim of this study was to investigate the possible association between single nucleotide variants (SNVs) in the calcium signaling pathway and HTN. METHODS: We genotyped three SNVs: rs1801253 (ADRB1), rs6108168 (PLCB1), and rs17249754 (ATP2B1) in a population of 131 patients with hypertension and 115 healthy controls from Kermanshah province, Iran. RESULTS: Our results showed a strong and significant association between the G allele and the GG and CG genotypes of the rs1801253 variant in the ADRB1 gene and susceptibility to hypertension. However, no significant association was found for the other two SNVs. In addition, the presence of the GCG haplotype (alleles from left to right: rs1801253, rs6108168, and rs17249754) appeared to confer a protective role against HTN. CONCLUSION: This study has made a significant contribution towards enhancing the comprehension of hypertension development, as well as the early identification of individuals who are at risk.
