Materials and methods: A meta-analysis of DFUs was conducted, comprising four independent genome-wide association studies from diabetes cohorts of European ancestry (AfterEU, Denmark; SDR, Sweden; GoShare, Scotland; DCS, Netherlands). This case-control study comprised a total of 980 cases (with DFU and DSPN) and 6196 controls (no history of DFU, but with DSPN). DSPN was defined as bilateral vibration sensation threshold ≥25V or absent sensation to monofilament. Logistic regression models were applied adjusting for sex, duration of diabetes and principal components. Summary statistics from the four European cohorts were meta-analysed using fixed effects inverse-variance based metaanalysis.
Results: In the GWAS meta-analysis, we identified three common single nucleotide polymorphisms (SNPs) that were suggestive (p-value
Conclusion: Three suggestive loci associated with DFU risk were identified in the current ongoing study. Two loci were located in COL4A2 and ALK, which have known roles in small vessel disease and neuronal development. Additional GWAS data from other participating centers will be added to the current analyses towards identification of loci associated with diabetic foot ulcers of neuropathic origin.
