OBJECTIVETo unveil the distribution of E-selectin G98T polymorphism in exon 2 and the S128R polymorphism in exon 4 of the Chinese Zhuang and Han ethnic groups in Guangxi province.

METHODSPolymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), gene sequencing and DNA sequencing were performed on 162 healthy Zhuangs and 170 healthy Hans.

RESULTSThe allele frequencies of G, T for E-selectin polymorphism in the exon 2 were 94.8% and 5.2% in Zhuangs, 95.3% and 4.7% in Hans, respectively; The allele frequencies of S, R for E-selectin polymorphism in the exon 4 were 92.0% and 8.0% in Zhuangs, 95.9% and 4.1% in Hans, respectively. There was significant difference in frequencies of genotype and allele in E-selectin S128R polymorphism between Zhuangs and Hans(chi-square test=4.482, P=0.034).

CONCLUSIONThere was significant difference in the E-selectin S128R polymorphism between Zhuangs and Hans. There was no significant difference in the E-selectin G98T polymorphism between Zhuangs and Hans.
