Abstract:
Objective To explore the correlation of the gene polymorphism of the two single nucleotide polymorphisms(SNPs)rs1443434andrs925489onforkheadboxEl(FOXE1)withthehighnormalthyroidstimulating hormone ( TSH) level in Chinese Han population. Methods 1 400 subjects with normal serum TSH and thyroid peroxidase antibody(TPOAb) levels were included. According to TSH or TPOAb levels, the subjects were divided into high normal TSH group(H-TSH group,n=195) and normal TSH control group(TSH control group,n=1 205) or high normal TPOAb group ( H-TPOAb group, n=711 ) and low normal TPOAb group ( L-TPOAb group, n=689 ) , respectively. The genotypes on the two SNPs of all the subjects were performed by whole-genome genotyping chips. Results There were significant differences in rs925489 genotypic distributions and allele frequencies between H-TSH group and TSH control group(both P<0. 05). The genotype TT and allele T in H-TSH group were significantly higher than those in TSH control group(89. 75% vs 83. 15%, 94. 62% vs 91. 29%). The normal TSH levels were positively associated with rs925489 genotypic distributions after adjustment for sex, age, and high density lipoprotein cholesterol(P<0. 01). There were no significant differences in rs1443434 genotypic distributions and allele frequencies between two TSH groups or two TPOAb groups. Conclusion FOXE1 rs925489 gene polymorphism may be correlated with the high normal TSH level in Chinese Han population.
