Figure 7-5 Partial map of the short arm of human chromosome 6 showing the molecular organization of the area containing the MHC loci, with details of the HLA Class I, II, and III genes. Map distances in kilobases were determined by pulsed field gel electrophoresis. Genes are not drawn to scale. Expressed genes are designated by filled boxes _ (|_|).
