| abstractText | We have cloned and sequenced the upstream regulatory region of tumor necrosis factor alpha (Tnfa) gene in 12 different mouse strains and identified an allelic polymorphism in the upstream regulatory region of the mouse Tnfa gene. The TNF allele found in the NZW strain is distinct from those of all other H-2 haplotypes, supporting our previous suggestion that this allele may be associated with a regulatory or structural defect. In addition, simple tandem repeat sequences (microsatellites) within the promoter region of the Tnfa gene and the 3' untranslated region of one of the members of the HSP70 family (Hsp68c clone) were utilized as genetic markers. Ten TNF size variants and twelve HSP70 variants were identified in over forty mouse strains. Using these markers in a set of congenic mice, we mapped this member of the HSP70 family to the central portion of the H-2 complex, centromeric to the Tnfa gene. The NOD and NZW strains carry unique HSP70 alleles based on the variability in the length of this marker. These findings raise the possibility that this protein may play a role in the association of the major histocompatibility complex with these autoimmune diseases. |
