I wanted free downloadable database for snps related to diabetes mellitus 2, any link for the same will be appreciated tried finding out many sites they had seperate snp infos , but i need an all inclusive downloadable dataset !
maybe this is not what you understand by "all inclusive", but you should try biomart.
Select "Ensembl Variation 93" as database and "Human Short Variants" as dataset.
Under "Filter" you will find "GENERAL VARIANT FILTERS" and there a list of phenotype. Select what ever you want (with CTRL+Mouse-Click you can select multiple entrys).
Under "Attributes" you can select what informations should be included in the output.
