[Absence of evidence for the association of single nucleotide polymorphisms in Annexin A1 gene with type 2 diabetes in Chinese].
OBJECTIVE
To identify single nucleotide polymorphisms (SNPs) in the annexin A1(ANXA1) gene and to analyze the association of these SNPs with type 2 diabetes in Shanghai Han population.


METHODS
SNPs in the promotor and exon regions (including intron sequence near splicing site) in the ANXA1 gene were screened by direct sequencing in 24 type 2 diabetes patients and were further genotyped by direct sequencing in another 171 type 2 diabetes patients and 189 normal control subjects.


RESULTS
The total sequence of ANXA1 gene is 6798 bp. And 7 SNPs were found; among them, 2 SNPs (-7974 C>T and -7040 G>T) were in promotor region, 3 SNPs in intron regions (+9059 A>G, +9204 C>T, +10486 A>G), 1 SNP in 5'-untranslation region (-6614 A>G) and 1 SNP in coding regions (+1784 A>G). These 7 SNPs were genotyped further and the results revealed that the allele frequencies of these SNPs showed no significant difference between the diabetic and the control groups (P>0.05).


CONCLUSIONS
There is no association of these SNPs in ANXA1 gene with type 2 diabetes in Shanghai Han population.
