OAS1 and type 1 diabetes mellitus: The association between these two SNPs and Type 1 diabetes has not been confirmed in a larger study, though others have concluded that there may be a very weak association between the rs1131454 (former rs3741981) and rs10774671 SNPs and Type 1 diabetes in a population of European descents, however these authors stated that this association might also be linked to other SNPs in the OAS1 locus [16,17].
