Islet amyloid polypeptide gene variation (IAPP) and the risk of incident type 2 diabetes mellitus: the Women's Genome Health Study.

Abstract

BACKGROUND:

Islet amyloid polypeptide (IAPP) gene variation has recently been implicated in type 2 diabetes mellitus (T2D). However, to date, no prospective epidemiological data are available.

METHODS:

The association between 10 IAPP tag-single nucleotide polymorphisms (tSNPs) and incident T2D was investigated in 22,715 Caucasian participants of the prospective Women's Genome Health Study. All were free of known cardiovascular disease, cancer, and diabetes at baseline. During a 13-year follow-up period, 1445 participants developed an incident T2D. Multivariable Cox regression analysis was performed to investigate the relationship between genotypes and T2D risk. Haplotype-based analysis was also performed.

RESULTS:

No evidence for an association of any of the tSNPs tested or haplotypes thereof with T2D risk.

CONCLUSIONS:

If corroborated in other large, prospective studies, the present findings further suggest that the IAPP gene locus may not be useful predictor for T2D risk assessment.
