The congenic segments are shown with respect to Inf2 (on left). The red rectangle represents the reduced Inf2. Mouse genes and human homologues and their chromosomal locations within the reduced Inf2 are shown at right. While most of the genes are in the same order in both species, some are not. These locations were identified using the MGI website:http://www.informatics.jax.org/searches/marker website and NCBI. The yellow highlighted genes are major histocompatibility complex (MHC) class II genes and TNF cluster genes identified as candidate genes using proof of concept experiments (see Figs. 5 and 6).
