Methods for identifying individuals at increased risk of diabetes are disclosed. The methods disclosed utilize the discovery of the DQw3.2 variant, which identifies a specific allelic polymorphism at a sinle gene locus. One preferred method utilizes a labeled probe to detect the DQw3.2 allele. This method involves estimating the size of the hybridizable DNA fragment generated by a specific restriction endonuclease and therefrom determining the presence of the allele. A second preferred method involves the serologic detection of the DQw3.2 allele. Within this method, immunocomplexes formed between two different MAb's and separate portions of a cell collection are detected and the presence or absence of the allele determined.
