HLA-DR alpha, -DX alpha, and DR beta III gene association studies in DR3 individuals.
In this study we have examined the results of probing with synthetic oligomers at the DR beta III locus, together with restriction fragment length polymorphisms defined by BglII digestion and a cDNA DR alpha probe, and Taq 1 digestion and a genomic DQ alpha probe. We have demonstrated heterogeneity of the human leukocyte antigen DR3 and close association of the DR alpha, DR beta III, and DX alpha genes. Two DR3-related preferential allelic associations have been identified, which may prove useful in family analysis as well as for investigations of DR3-related diseases.
