Abstract

OBJECTIVE:

To investigate associations between single nucleotide polymorphisms (SNPs) rs2228314 and rs2267443 in the sterol regulatory element binding protein-2 gene (SREBP-2) and knee osteoarthritis (OA) susceptibility in a Chinese Han population.

METHODS:

SREBP-2 rs2228314 and rs2267443 polymorphisms were genotyped in patients with knee OA and age- and sex-matched OA-free controls from a Chinese Han population.

RESULTS:

A total of 402 patients with knee OA and 410 controls were enrolled in the study. GC and CC genotypes of rs2228314, and variant C, were associated with a significantly increased risk of knee OA. On stratification analysis, the association between the risk of OA and rs2228314 GC heterozygotes compared with GG homozygotes was stronger in females and those aged >65 years. In contrast, the GA and AA genotypes of rs2267443 were not significantly associated with the risk of knee OA, even after further stratification analysis according to age or sex.

CONCLUSIONS:

SREBP-2 rs2228314 G to C change and variant C genotype may contribute to knee OA risk in a Chinese Han population.
