Aims

Several studies have shown associations between the composition of polyunsaturated fatty acids (PUFAs) in various tissues and type 2 diabetes mellitus (T2DM) development in European populations. Genetic variants of fatty acid desaturase (FADS) contribute to the variations of PUFA composition. Here we have explored whether similar correlations are also true among Chinese Han people.

Methods

A case-control study was employed to examine this correlation in Han Chinese people. The study included 421 healthy adults and 331 T2DM patients.

Results

The ratio of arachidonic acid/linoleic acid (AA/LA), which reflects Δ6 desaturase activity, was significantly increased in T2DM patients. Furthermore, the ratio of eicosapentaenoic acid/α-linolenic acid (EPA/ALA), which reflects Δ5 desaturase activity, was markedly decreased in T2DM patients. Importantly, among four single nucleotide polymorphisms (rs174545, rs2072114, rs174602 and rs174616) in the FADS1-FADS2 gene cluster, only minor allele (T) of rs174616 was associated with decreased risk of T2DM in both codominant and dominant models after adjustment for age, gender and BMI. Furthermore, the ratio of AA/LA in both controls and T2DM was reduced in T carriers while an increased proportion of LA was seen in T2DM patients compared with control patients.

Conclusion

These data suggest that in northern Han Chinese people, the minor allele (T) of rs174616 in the FADS1-FADS2 gene cluster is associated with a decreased conversion rate of LA to AA, which may contribute to decreased reduced risk of developing T2DM."xsd:string
