PG - 419-26 AB - The cloning of large genomic fragments corresponding to the major histocompatibility complex (MHC) class I region provides the necessary framework for a better understanding of its organization and for the localization of new genes involved in MHC-associated disease. Two human genomic libraries constructed in yeast artificial chromosomes (YACs) have been prepared using complete Not I or Mlu I digestion of source DNA. From these libraries three YAC clones with inserts belonging to the MHC class I region have been isolated. They correspond to exact copies of three genomic fragments of 210, 145, and 50 kilobases (kb), respectively and have been precisely located in the restriction map of the region. Detailed rare-cutter restriction maps of the inserts have been generated. Within these clones we have demonstrated the presence of two class I genes, one of which is HLA-E, and of at least three Hpa II tiny fragment (HTF) islands, corresponding to three putative new transcribed sequences. End clones, which are of particular interest in the extension and refinement of the regional map, have been rescued by systematic subcloning of purified YACs.
