RESUMEN
OBJECTIVE: To explore the relationship between angiotensinogen (AGT) gene M235T and TCM syndrome type in essential hypertension (ET) patients. METHODS: The gene mutation frequency of AGT M235T in 168 ET patients and 42 nomotensive (NT) subjects were determined using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. RESULTS: There was a significant difference in AGT M235T gene mutation between patients of Gan-fire exuberant type and those of yin-yang deficiency type (P < 0.01), homozygote type TT appeared with higher frequency. Multivariate regression linear analysis demonstrated that the genotypes of AGT M235T was correlated with the prognosis of ET to a certain degree. CONCLUSION: Gene mutation of AGT M235T may be associated with the genesis and development of ET, and the TCM syndrome type of ET has its own intrinsic molecular biological background.
