Abstract
We have assembled a contig of 81 yeast artificial chromosome clones that spans 8 Mb and contains the entire major histocompatibility complex (Mhc) from mouse strain C57BL/6 (H2b), and we are in the process of assembling an Mhc contig of bacterial artificial chromosome (BAC) clones from strain 129 (H2bc), which differs from C57BL/6 in the H2-Q and H2-T regions. The current BAC contig extends from Tapasin to D17Leh89 with gaps in the class II, H2-Q, and distal H2-M regions. Only four BAC clones were required to link the class I genes of the H2-Q and H2-T regions, and no new class I gene was found in the previous gap. The proximal 1 Mb of the H2-M region has been analyzed in detail and is ready for sequencing; it includes 21 class I genes or fragments, at least 14 olfactory receptor-like genes, and a number of non-class I genes that clearly establish a conserved synteny with the class I regions of the human and rat Mhc.

Abstract
The H2-M region is the most distal part of the mouse major histocompatibility complex (Mhc) and is likely to include the distal breakpoint of the fourth t-inversion, In(17)4d. The conserved synteny breakpoint between mouse and human is located in the H2-M region between D17Leh89, a putative olfactory receptor gene, and Pgk2 (phosphoglycerate kinase 2). To analyze the H2-M region, we screened a mouse bacterial artificial chromosome (BAC) library, using the D17Mit64, D17Tu49, D17Leh89, D17Leh467, and Pgk2 markers. Thirty-eight BAC clones were obtained and mapped in five clusters, and 25 sequence-tagged site (STS) markers were newly developed. The regions surrounding D17Tu49 and D17Leh467 are abundant in L1 repeat sequences and may, therefore, be candidates for the breakpoints of conserved synteny and t-inversion. D17Leh89 was linked to D17Mit64 by two contiguous BAC clones. The Aeg1 (acidic epididymal glycoprotein 1) and Aeg2 genes were mapped close to Pgk2, on the same BAC clones. The genetic length between D17Leh89-D17Mit64 and Pgk2-Aeg can be estimated as 0.5-0.7 centiMorgan (cM), and the most distal class I gene, H2-M2, can be placed 0.3-1.0 cM proximal to the t-inversion breakpoint. A recombinational hotspot is suggested to be located between Aeg and Tpxl in an interspecific cross of (C57BL/6J x Mus spretus).

Abstract
We have refined and extended the map of the distal half of the human major histocompatibility complex. The map is continuous from HLA-E to 1000 kb telomeric of HLA-F and includes six new markers and genes. In addition, the corresponding sequences that were not previously mapped in the mouse genome have been located. The human and the mouse organizations have therefore been compared. This comparison allows us to demonstrate that the structure of the distal part of the MHC is similar in the two species. In addition, this comparison shows the presence of a breakpoint of synteny telomeric of the distal part of the H-2 region. Indeed, the region telomeric of HLA in human is found on a chromosome different from that carrying H-2 in mouse. The mapping analysis of paralogous genes (structurally related genes) around the breakpoint shows that the human organization probably represents the putative human/mouse ancestral one. This evolutionary breakpoint was precisely mapped in human, and the surrounding region was cloned into yeast artificial chromosomes. Finally, we show that the region found around the breakpoint was involved several times in chromosome recombinations in the mouse lineage, as it seems to correspond also to the t-complex distal inversion point.

Abstract
Intra-H-2 recombinant congenic strains are widely used to localize traits to specific subregions of the major histocompatibility complex and have provided evidence for the existence of meiotic recombinational hotspots in mammals. Forty-seven intra-H-2 recombinant strains, including 12 not previously reported, have been identified by serological typing in our laboratory. We have extended the analysis of the crossover sites in these mice using DNA markers for Ab, Aa, Eb, Ea, Cyp21-ps, D17Tu3, Bat7, and Bat5. The recombinant chromosomes of these congenic strains include loci derived from the a, b, f, k, p, q, r, s, u, and v haplotypes of H-2, providing a diverse panel of strains. Although some alleles of Bat7 could not be distinguished from one another, results from the majority of strains indicated a probable gene order of C4Slp/D17Tu3-Bat7-Bat5-H-2D. No recombinants between Cyp21-ps, C4Slp, and D17Tu3 were observed. The crossover sites in 31 of the 47 intra-H-2 recombinants were within the C4Slp/D17Tu3-H-2D interval; of these 31 crossovers, three were bracketed by D17Tu3 and Bat7, ten by Bat7 and Bat5, seven by Bat5 and H-2D, and 11 by D17Tu3 and Bat5. The results from all 47 strains suggest recombinational hotspots within the C4Slp/D17Tu3-H-2D interval and emphasize the influence that specific haplotypes can have on preferred crossover sites.

Abstract
We have cloned and characterized five new class I genes from the M region at the distal end of the H-2 complex of the BALB/c mouse. M4, M5, and M6 are clustered on two overlapping cosmids, and M7 and M8 are located on another cosmid together with the previously cloned M1 gene, to which they are most closely related. M4, M6, and M7 are full-length class I genes (exons 1 through 5 were identified) but with stop codons or frameshifts that mark them as pseudogenes, and only exons 4 and 5 remain of M8. M5 has complete open reading frames in exons 1 through 5 and intact splice signals; it has the potential to encode a divergent class I major histocompatibility molecule, but no transcripts were found. These genes provide probes for studying the evolution of class I genes in rodents and for the mapping and cloning of genes at the end of the distal inversion in t haplotype chromosomes.

Abstract
Intracisternal A-particle (IAP) proviral elements are moderately reiterated and widely dispersed in the mouse genome. Oligonucleotide probes have been derived from three distinctive IAP element subfamilies (LS elements) that are transcriptionally active in normal mouse B- and T-cells. In HindIII digests, LS element-specific oligonucleotides each react with a limited number of restriction fragments that represent junctions between proviral and flanking DNA. These fragments have characteristic strain distribution patterns (SDPs) which are polymorphic in the DNAs of different mouse strains. We have established chromosomal assignments for 44 LS proviral loci by comparing their SDPs with those of known genetic markers in the BXD set of RI mouse strains. Some of the loci have also been scored in the CXB RI set. The IAP LS loci can provide a significant number of markers with a recognized genetic organization to the mouse genome map.

Abstract
To isolate DNA markers from mouse chromosome 17, a genomic phage library was constructed from the mouse-hamster CMGT cell hybrid RcE-B52. This hybrid contains a chromosomal fragment from the distal end/flanking region of the t complex on mouse chromosome 17. Recombinants of mouse origin were identified by using a panel of mouse-specific repetitive sequences as a probe. A total of 1,500 mouse phage recombinants were isolated. These were found to represent 250-300 individual recombinants, comprising about 4 Mbp of cloned mouse DNA. The pooled mouse recombinant phages were used to construct an Eag I end-library. This was achieved by the specific insertion of a marker plasmid in Eag I recognition sites when present in the mouse inserts of the recombinant phages. The Eag I end-fragments were subsequently subcloned using a simple procedure taking advantage of the inserted plasmid. A total of 56 individual Eag I end-fragments were identified. These were found to contain recognition sites for rare cutting enzymes at high frequency. A large proportion (73%) were found to be evolutionarily conserved in human DNA. Furthermore, a significant fraction of these fragments, two of six tested, appears to detect specific cDNAs in a 8.5-day mouse embryo cDNA library.

Abstract
Three anonymous chromosome 17 DNA markers, D17Tu36, D17Tu43, and D17Le66B, differentiate between house mouse species and/or between t chromosomes. The D17Tu36 probe, which maps near the Fu locus and to the In(17)4 on t chromosomes, identifies at least 15 haplotypes, each haplotype characterized by a particular combination of DNA fragments obtained after digestion with the Taq I restriction endonuclease. Ten of these haplotypes occur in Mus domesticus, while the remaining five occur in M. musculus. In each of these two species, one haplotype is borne by t chromosomes while the other haplotypes are present on non-t chromosomes. The D17Tu43 probe, which maps near the D17Leh122 locus and to the In(17)3 on t chromosomes, also identifies at least 15 haplotypes in Taq I DNA digests, of which nine occur in M. domesticus and six in M. musculus. One of the nine M. domesticus haplotypes is borne by t chromosomes, the other haplotypes are borne by non-t chromosomes; two of the six M. musculus haplotypes are borne by t chromosomes and the remaining four by non-t chromosomes. Some of the D17Tu43 haplotypes are widely distributed in a given species, while others appear to be population-specific. Exceptions to species-specificity are found only in a few mice captured near the M. domesticus-M. musculus hybrid zone or in t chromosomes that appear to be of hybrid origin. The D17Leh66B probe, which maps to the In(17)2, distinguishes three haplotypes of M. domesticus-derived t chromosomes and one haplotype of M. musculus-derived t chromosomes. Because of these characteristics, the three markers are well suited for the study of mouse population genetics in general and of t chromosome population genetics in particular. A preliminary survey of wild M. domesticus and M. musculus populations has not uncovered any evidence of widespread introgression of genes from one species to the other; possible minor introgressions were found only in the vicinity of the hybrid zone. Typing of inbred strains has revealed the contribution of only M. domesticus DNA to the chromosome 17 of the laboratory mouse.

Abstract
We describe a general method of determining the recombination fraction between a polymorphic locus and the centromere in any species where single oocytes can be obtained. After removal of the first polar body, each oocyte is analyzed by PCR. The frequency of oocytes heterozygous at the polymorphic locus is used to estimate the recombination fraction. We estimate a recombination fraction of 0.15 between the mouse major histocompatibility complex (H-2) and the centromere of chromosome 17.

Abstract
Heterotrimeric guanine nucleotide binding proteins (G proteins) transduce extracellular signals received by transmembrane receptors to effector proteins. The multigene family of G protein alpha subunits, which interact with receptors and effectors, exhibit a high level of sequence diversity. In mammals, 15 G alpha subunit genes can be grouped by sequence and functional similarities into four classes. We have determined the murine chromosomal locations of all 15 G alpha subunit genes using an interspecific backcross derived from crosses of C57BL/6J and Mus spretus mice. These data, in combination with mapping studies in humans, have provided insight into the events responsible for generating the genetic diversity found in the mammalian alpha subunit genes and a framework for elucidating the role of the G alpha subunits in disease.

Abstract
The human RAP1A gene encodes a protein that apparently can antagonize the function of oncogenic ras genes in gene transfer experiments, but its normal function is unknown. To understand the function of this gene, we have undertaken a study of the mouse homolog, Rap1a. The complete coding sequence of a mouse Rap1a cDNA has been determined, and genomic clones representing three distinct Rap1a species were recovered. We find that Rap1a is located on distal mouse Chromosome (Chr) 3 near Nras, Ampd-1, Tshb, Ngfb, and Atp1a1. Two related sequences (Rap1a-rs1 and Rap1a-rs2) were also characterized. Rap1a-rs1, which was not localized, has a sequence very similar to the Rap1a cDNA, suggesting that it has been recently acquired by the mouse genome. Rap1a-rs2 is more distantly related to the gene sequence and is located on Chr 2 near Actc-1.

Abstract
Loss of heterozygosity is a significant oncogenetic mechanism and can involve a variety of mechanisms including chromosome loss, deletion, and homologous interchromosomal mitotic recombination. Analysis of H-2 antigen-loss variants from heterozygous murine cell lines provides an experimental system to estimate the relative contributions of different mechanisms for allele loss and to compare the chromosomal patterns of mitotic and meiotic recombination. Cytotoxic anti-H-2D antibodies and complement were used to isolate 161 independent target antigen-negative clones from H-2d/H-2b heterozygous cell lines; of these, 131 (84.5%) lost the allele encoding the target antigen. Allele-loss variants were typed and scored as either heterozygous or homozygous for six H-2D-proximal chromosome 17 markers and for one distal marker by restriction enzyme-site variations and Southern analysis. A single mitotic crossover could account for 50 clones (37%), with heterozygosity for at least one proximal marker and loss of heterozygosity for all markers distal to the putative recombination site. Eighty-two allele-loss variants (60%) were homozygous for all markers; the origin of these clones could be either chromosome loss or mitotic recombination between the centromere and the most proximal marker. Only 4 clones (3%) arose through more complex events such as multiple crossovers or deletion. A mitotic linkage map for mouse chromosome 17 was constructed, and the gene order deduced from somatic recombination was identical to that obtained by conventional transmission genetics. These results demonstrate that mitotic recombination is a common event leading to allele loss, in spite of the lack of evidence for frequent somatic pairing of homologous chromosomes. Mitotic mapping provides a defined system for comparison of mitotic and meiotic recombination and may lead to practical advances for elucidating somatic mechanisms of oncogenesis and for gene therapy in targeting mutations to specific sites through homologous recombination.

Abstract
Four human RAS-like cDNAs and a mouse genomic DNA fragment were used to define novel mouse Ras-like genes and gene families. Inheritance of DNA restriction fragment length variants associated with these genes in recombinant inbred and backcross mice allowed definition of 12 genetic loci, nine of which were mapped, to chromosomes (Chr) 2, 4, 7, 8, 9, and 17. Two possible clusters of Ras-like and/or G protein genes were identified, on Chrs 9 and 17.

Abstract
t-haplotypes occupy a region on chromosome (Chr) 17 which slightly overlaps the ends of the T-H-2 interval. The wild-type form of this 14 centi-Morgan (cM) region was mapped in a multilocus backcross (C57BL/10-T x C3H)F1 x C57BL/10 using 15 DNA probes on Southern blots of the DNA extracted from 53 animals which were recombinants in the T-H-2 interval. Each recombinant was also progeny-tested to ascertain its Hybrid sterility-1 (Hst-1) genotype by crossing to PWB/Ph, a Mus musculus-derived inbred strain. The limit of resolution of the cross was 0.27 cM. The map distances have been determined for the DNA loci in the T-H-2 interval and the Hst-1 gene was mapped in close vicinity to the D17Rp17 locus.

Abstract
Fifty-five single-copy DNA probes were isolated from the library LL06NS01, which was constructed from a complete HindIII digest of a flow-sorted human chromosome 6. Because chromosomes from a human x Chinese hamster somatic cell hybrid were used as the starting material for the flow-sorting, the library could be expected to contain some contaminating Chinese hamster DNA as well as DNA from human chromosomes other than 6. Thirty-seven of the 55 probes, however, were shown to map to human chromosome 6 by Southern blot hybridization with DNA from a panel of somatic cell hybrids. Eleven of the probes were mapped further by in situ hybridization. Four probes were localized to the short arm of chromosome 6, six to the long arm, and one to the centromeric region.

Abstract
We describe a genetic analysis of l(17)-2Pas, an embryonic lethal mutation on murine chromosome 17. Males transmitted the l(17)-2 allele to only 38% of their offspring, whereas females transmitted this allele at 50%. Two-point crosses revealed tight linkage between l(17)-2 and brachyury (T), and deletion mapping placed l(17)-2 outside of the hairpin-tail deletion (Thp). To map this mutation more precisely, we intercrossed hybrid mice that carry distinct alleles at many classical and DNA loci on chromosome 17 and obtained 172 animals recombinant in the T to H-2 region. Strong positive interference was observed over the 14 cM interval from T to H-2K. Thus, a single recombinant can be informative; one such recombinant places l(17)-2 distal of the molecular marker D17Leh66D. Robust genetic maps can be constructed with multilocus crosses that share anchor loci. DNA markers can be interpolated onto these maps retrospectively.

Abstract
The suppression of crossing-over and the consequent linkage disequilibrium of genetic markers within the t complex of the house mouse is caused by two large and two short inversions. The inversions encompass a region that is some 15 centiMorgans (cM) long in the homologous wild-type chromosome. The limits of the proximal inversions are reasonably well-defined, those of the distal inversions much less so. We have recently obtained seven new DNA markers (D17Tu) which in wild-type chromosomes map into the region presumably involved in the distal inversions of the t chromosomes. To find out whether the corresponding loci do indeed reside within the inversions, we have determined their variability among 26 complete and 12 partial t haplotypes. In addition, we also tested the same collection of t haplotypes for their variability at five D17Leh, Hba-ps4, Pim-1, and Crya-1 loci. The results suggest that the distal end of the most distal inversion lies between the loci D17Leh467 and D17Tu26. The proximal end of the large distal inversion was mapped to the region between the D17Tu43 and Hba-ps4 loci, but this assignment is rather ambiguous. The loci Pim-1, Crya-1, and the H-2 complex, which have been mapped between the Hba-ps4 and Grr within the large distal inversion, behave as if they recombine from time to time with their wild-type homologs.

Abstract
An interspecific backcross between lab mice and Mus spretus was used to construct a multilocus map of Chromosome 17 consisting of 12 new anonymous loci and 9 anchor loci. In addition, 7 anonymous DNA loci were added to the Chr 17 map for the BXD strains. Although we were able to identify readily the most likely gene order in the interspecific backcross, we found no evidence for an unambiguous gene order using the BXD recombinant inbred strains. Comparison of the interspecific backcross map and the BXD RI strain map revealed evidence in the interspecific backcross for a longer total genetic length, enhanced recombination distal to H-2, a segment showing suppressed recombination, and strong interference.

Abstract
Congenic mouse strains are widely used in mapping traits to specific loci or short chromosomal regions. The precision of the mapping depends on the information available about the length of the differential segment--the segment introduced from the donor into the background strain. Until recently, very few markers flanking the differential locus were known and consequently the length of the foreign segment could only be determined imprecisely. Now, in an attempt to construct a map of the mouse chromosome 17, we have produced a set of DNA markers distributed along the chromosome. These markers provide a new opportunity to measure the length of the differential segment of the congenic strains and thus increase their usefulness for gene mapping. Here we examined the DNA of 96 H-2 congenic strains using 30 DNA markers; of these, the most proximal is located roughly 1.5 centiMorgans (cM) from the centromere and the most distal is about 20 cM telomeric from the H-2 complex (the complex itself being some 20 cM from the centromere). The mapping depends on polymorphism among the input strains and can therefore establish only the minimal length of the differential segment. This point is emphasized by the fact that the average observed length of the differential segment is only about one half of the expected values.
