Genes identified in the HLA class I region

Location	Name	Orientation	Exons	Homology or prominent features

Location is indicated by nucleotide positions numbered from the 5′ end of the MICB gene. The color code has been established as follows: orange indicates known expressed genes, green possibly expressed sequences, and red new expressed loci, i.e. for which cDNA clones were previously reported but where physical location was unknown or ambiguous. Regarding pseudogene, black depicts known pseudogenes and blue new ones. Gene orientation from centromere to telomere is shown by the letter C, and + depicts the opposite.
