Abstract:
Objective To explore the association between 1425G/A single nucleotide polymorphism(SNP)of protein kinase Cη gene(PRKCH)and cerebral infarction in Jiangsu Han population.Methods 255 patients with cerebral infarction and 225 controls were recruited in our case-control study.The 1425G/A in PRKCH gene was detected by direct sequencing of PCR products.Data were coded and entered in SPSS Windows(version 13.0).Results The frequencies of the GA+AA genotypes(56.86%)and A allele (36.27%)in cerebral infarct group were significantly higher than those in control group(44.44%and24.67%.χ2=7.377,P=0.007 and χ2=15.104,P<0.01).Further analysis indicated that the genotypes(63.09%)and alleles(40.27%)frequencies were statistically different between lacunar infarction subtype and controls(44.44%and 24.67%;χ2=11.744,P=0.Ol and χ2=20.445,P<0.01).Logistic regression analysis revealed that hypertension,diabetes mellitus.hyperlipidemia and the A allele of 1425G/A polymorphism were independent risky factors for lacunar infarction.Conclusions The SNP 1425G/A in PRKCH is closely associated with cerebral infarction.particularly with lacunar infarction.
