Association of genetic polymorphism in phenylethanolamine-N-methyl transferase with essential hypertension in Changsha Han people / 中南大学学报(医学版)

ABSTRACT

OBJECTIVE@#To investigate the association of phenylethanolamine-N-methyl transferase (PNMT) G-390A genetic polymorphism with risk of essential hypertension (EH) in Changsha Han people.@*METHODS@#A case-control association study was performed in 400 patients with essential hypertension (EH) and 388 normotensive subjects. PNMT G-390A was genotyped using polymerase chain reaction-restriction fragment length polymorphism (PCR-FRLP).@*RESULTS@#The genotype frequencies for the -390 GG, GA, and AA were 39.3%,50.0%, and 10.8%, respectively in EH patients, and were 43.6%,45.6%, and 10.8%, in normal subjects. No significant difference in either genotypic frequency (P=0.433) or allele frequency (P=0.378) of PNMT G-390A between EH patients and normals was observed. When by gender, there was significant difference in genotypic frequency (P0.05).@*CONCLUSION@#PNMT G-390A polymorphism is possibly associated with EH risk in male Chinese Han population in Changsha.
