    In humans, susceptibility to several immunopathologic diseases maps to a conserved block encompassing the polymorphic BAT1, NFKBIL1 (IKBL) and TNF genes in the central MHC. As a pre-requisite for studies of these genes in animal models, we characterized Bat1a and Nfkbil1 in inbred mice differing in their H2 haplotype. We identified two indels and nine single nucleotide polymorphisms (SNP) upstream of Nfkbil1, one indel, nine SNP upstream of Bat1a and a synonymous SNP in exon 2 of Bat1a. H2(g7) and H2(b) mice yielded identical Bat1a and Nfkbil1 sequences. Real time PCR (RT-PCR) showed Bat1a was expressed in adult brain, heart, kidney, liver, lung, pancreas and spleen. Expression of Bat1a was higher in brain and liver of 15-day embryos compared to 1-day old mice and increased moderately in liver and lung of adult mice 2-4h after LPS challenge. Nfkbil1 expression was low or undetetectable in all tissues and cell lines.
