A non-synonymous variant in SLC30A8 is not associated with type 1 diabetes in the Danish population

Genome-wide association scans in type 2 diabetes (T2D) have identified a risk variant, rs13266634 (Arg325Trp), in SLC30A8 on chromosome 8. SLC30A8 encodes a beta-cell specific zinc-ion transporter and rs13266634 has been shown to affect insulin secretion. Recently, autoantibodies for Slc30A8 with high predictive value were demonstrated in individuals with type 1 diabetes (T1 D), making this gene an interesting T1 D candidate gene. We genotyped rs13266634 in 3008 cases and controls and 246 families from Denmark. Association to T1 D could not be demonstrated. (c) 2008 Elsevier Inc. All rights reserved.
