Association of sterol regulatory element-binding transcription factor gene polymorphisms with ischaemic stroke
1Department of Neurology, Xiangya Hospital, Central South University, Changsha, China.
Objective:
To explore the association between polymorphisms of the sterol regulatory element-binding transcription factor (SREBF) gene and ischaemic stroke.
Methods:
The SREBF1c 54G>C and SREBPF2 1784G>C genotypes were assessed using restriction fragment length polymorphism analysis in 446 Han Chinese ischaemic stroke patients and 355 Han Chinese control subjects without cerebrovascular disease.
Results:
The frequencies of the SREBF2 1784G>C CC genotype and the C allele were significantly higher in the ischaemic stroke group than in controls. Patients with ischaemic stroke who had the SREBF2 1784G>C CC genotype had significantly lower high-density lipoprotein (HDL) levels, compared with ischaemic stroke patients and control subjects with the GC or GG genotypes. Multivariate logistic regression analysis revealed a significant positive association between SREBF2 1784G>C and ischaemic stroke; an inverse association was observed between HDL level and risk of ischaemic stroke.
Conclusions:
The CC genotype of the SREBF2 1784G>C polymorphism was associated with an increased risk of ischaemic stroke, possibly through decreasing the HDL level, which was inversely associated with the risk of ischaemic stroke.
