Human leukocyte antigen (HLA)-DR3 haplotypes are associated with susceptibility to type 1 diabetes (T1D). Reports from Northern European populations show that an allele (D6S273*2) at a microsatellite mapping to HLA class III marks an extended DR3-B18 haplotype associated with increased susceptibility to T1D. Consistent with previous reports, D6S273*2 marked a highly predisposing DR3 haplotype in European origin, multiplex families from the USA. Furthermore, we observed on DR3 haplotypes that other D6S273 alleles were also significantly associated with both increased transmission (D6S273*5; P < 0.02) and decreased transmission (D6S273*7; P < 0.05) to affected individuals. The differential transmission was most evident among DR3-B8 haplotypes. Neither HLA-B*1801 nor any alleles of D6S273 were associated with increased T1D predisposition on DR4 haplotypes. These data indicate that multiple alleles of D6S273 mark a susceptibility locus whose effect we were able to detect only among DR3 haplotypes but not limited to DR3-B18 haplotypes.
