Association between chromosome 9p21 polymorphism and the large-artery atherosclerosis stroke / 中国神经精神疾病杂志

ABSTRACT

Objective To explore the association between rs7049105, rs647188, rs1333035 of chromosome 9p21 and the LAS among Chinese Han population of Changsha;to explore the association between rs7049105, rs647188, rs1333035 and the LAS among patients with evidence of cephalic and cervical vessel atherosclerosis. Methods The present study com?prised 229 LAS patients and 233 healthy controls. The 233 controls which we defined control group 1. In the controls, 150 (64.38%)controls with evidence of atherosclerosis were defined as control group 2, 83(35.62%)controls without evidence of atherosclerosis were defined as control group 3. The sample genotyping was detected using MALDI-TOF-MS. Results There was no polymorphism of rs647188 among case group and control group 1. There was no significant difference in the polymorphism distribution of rs7049105 and rs1333035 between the case group and control group 1 and 3 (P>0.05). There may be no significant different in the polymorphism distribution of rs7049105 between the case group and control group 2 . The rs1333035 was associated with risk of LAS among patients with evidence of cephalic and cervical vessel atherosclerosis (χ2=6.502,P=0.039). Conclusions The rs10757274 and rs7049105 polymorphism in the chromosome 9p21 may not be as?sociated with risk of LAS among Han population of Changsha. There may be no polymorphism of rs647188 among Han popu?lation of Changsha. The rs1333035 polymorphism may be associated with plaque rupture and thrombosis.
