Abstract
We describe a detailed somatic cell hybrid map of human chromosome 17q11.2-q23, containing the familial breast and ovarian cancer locus (BRCA1) and highly informative closely linked markers. An X-irradiation panel of 38 hamster/human and mouse/human hybrids with fragments of chromosome 17 was generated and characterized with 22 STS markers from this chromosome. A detailed map of 61 probes onto chromosome 17q, subdividing the chromosome arm into 25 regions, was done by using a panel of hybrids with well-defined breakpoints and nine chromosome-mediated gene transfectants. Our localization of RARA, TOP2, EDH17B1 and 2, and possibly WNT3, between THRA1 and D17S181, two markers known to flank BRCA1, suggests that any of these is a potential candidate for the BRCA1 locus. The marker D17S579 (Mfd188), which is believed to be very close to BRCA1, maps closest to the EDH17B genes.

Abstract
Acute promyelocytic leukaemia (APL; AML M3) is identified by a unique t(15;17) translocation which fuses the PML gene to the retinoic acid receptor alpha gene (RARA). Reverse transcription coupled with the polymerase chain reaction (RT-PCR) has been used to develop a diagnostic test for APL based on the PML-RARA fusion message. Separate PCR assays were designed to amplify either PML-RARA (15q+ derived) or RARA-PML (17q- derived) chimaeric transcripts. PML-RARA transcripts were detected in every case from a series of 18 APL patients with cytogenetically confirmed t(15;17) translocations, whereas RARA-PML messages were detected in only 67% (12/18) of these patients. This suggests that it is the 15q+ derivative which mediates leukaemogenesis. Furthermore the PCR approach (or Southern analysis) may be used to identify in which of the alternative PML introns the breakpoint occurs; 52% of cases (15/29 patients) utilize a 5' PML intron and 48% the 3' intron (14/29 cases). Neither the choice of PML intron nor the expression of the 17q- derivative could be correlated with the microgranular variant of APL (M3V), overall survival rate, age, sex or presence of coagulopathy. Finally, the fusion message is undetectable in five remission samples. This indicates a possible use for RT-PCR in monitoring remission patients for evidence of relapse.

Abstract
A human genomic fragment comprising the cellular retinoic acid binding protein (CRABP) gene was isolated. By using a panel of somatic cell hybrids, this gene could be assigned to human chromosome 15. Subsequently, a possible involvement of the CRABP gene in translocation (15;17) (q22;q11) positive acute promyelocytic leukemia (APL) was investigated. Although transposition of the CRABP gene could be demonstrated, we did not observe any gross CRABP rearrangement in a series of primary APL patients, nor in the acute myeloblastic leukemia cell line HL-60. Thus, the observed lack of CRABP expression in these leukemic cells may not be caused by disruption of its gene. CRABP maps to the region 15q22-qter.

Abstract
The von Recklinghausen neurofibromatosis 1 (NF1) locus has been previously assigned to the proximal long arm of chromosome 17, and two NF1 patients have been identified who have constitutional balanced translocations involving 17q11.2. We have constructed a cosmid library from a chromosome-mediated gene transfectant, KLT8, that contains approximately 10% of chromosome 17, including 17q11.2. Cosmids isolated from this library have been mapped across a panel of somatic cell hybrids, including the hybrids from the two patients, and have been localized to seven small regions of proximal 17q. We have 5 cosmids that map directly above the two NF1 translocations, and 11 cosmids that map directly below. Of these, 2 cosmids in each region are linked to the disease locus and 3 of these cosmids show no recombination. One distal cosmid, 2B/B35, detects the two NF1 translocations by pulsed-field gel analysis and has been used to produce a long-range restriction map that covers the translocations.

Abstract
The insulin-like growth factor I (IGF-1) mediates the actions of pituitary growth hormone in a variety of tissues. Its receptor (IGF1R) displays considerable structural similarity to the insulin receptor. In humans, the IGF1R gene has been mapped near FES, the cellular counterpart of the feline sarcoma virus transforming gene v-fes, at the q25-q26 region of human chromosome 15 (HSA15). Here, we report the mapping of mouse Igf1r to mouse chromosome 7 (MMU7) by somatic cell hybrid analysis. This result, along with the prior assignment of the loci for mitochondrial isocitrate dehydrogenase and FES to human chromosome 15 and mouse chromosome 7, suggest a conserved autosomal synteny group on the distal long arm of HSA15 and in the center of MMU7.

Abstract
Recombinant inbred strain and interspecific backcross mice were used to create a molecular genetic linkage map of the distal portion of mouse chromosome 2. The orientation and distance of the Ada, Emv-13, Emv-15, Hck-1, Il-1a, Pck-1, Psp, Src-1 and Svp-1 loci from the beta 2-microglobulin locus and the agouti locus were established. Our mapping results have provided the identification of molecular markers both proximal and distal to the agouti locus. The recombinants obtained provide valuable resources for determining the direction of chromosome walking experiments designed to clone sequences at the agouti locus. Comparisons between the mouse and human genome maps suggest that the human homolog of the agouti locus resides on human chromosome 20q. Three loci not present on mouse chromosome 2 were also identified and were provisionally named Psp-2, Hck-2 and Hck-3. The Psp-2 locus maps to mouse chromosome 14. The Hck-2 locus maps near the centromere of mouse chromosome 4 and may identify the Lyn locus. The Hck-3 locus maps near the distal end of mouse chromosome 4 and may identify the Lck locus.

Abstract
Ten genomic DNA probes, subcloned from inserts derived from a phage library constructed from the DNA of flow-sorted chromosomes, have now been mapped to locations within 15q11-15q13. By dosage blotting and densitometry, 5 of these probes map to the 15q11.2-15q12 segment missing in one 15 chromosome of a Prader-Willi syndrome (PWS) patient with a prominent cytological deletion. A sixth probe most likely maps to the same region. The other 4 probes map outside of this segment but within 15q11-15q13. Several of the 15q11.2-15q12 probes, and a cDNA probe homologous to one, have been used to test the DNA from 8 patients exhibiting a wide range of the clinical manifestations expected for PWS patients. DNA deletion was observed in all 3 patients with cytological 15q1 deletions as well as in a patient with an unbalanced (Y;15) translocation. DNA from 1 PWS patient with an unbalanced (5;15) translocation and an inverted duplication of the short arm and proximal long arm of 15 showed at least 1 and possibly 2 extra copies of each genomic probe tested. In the other 3 patients with no cytological deletions, no DNA deletions were found. Thus, the molecular probes described can be used in most PWS patients to analyze the region of proximal 15q implicated in this syndrome.

Abstract
We used somatic-cell hybrids, containing as their only human genetic contribution part or all of chromosome 17, as donors for chromosome-mediated gene transfer. A total of 54 independent transfectant clones were isolated and analyzed by use of probes or isoenzymes for greater than 20 loci located on chromosome 17. By combining the data from this chromosome-mediated gene transfer transfectant panel, conventional somatic-cell hybrids containing well-defined breaks on chromosome 17, and in situ hybridization, we propose the following order for these loci: pter-(TP53-RNP2-D17S1)-(MYH2-MYH1)-D17Z 1-CRYB1-(ERBA1-GCSF-NGL)-acute promyelocytic leukemia breakpoint-RNU2-HOX2-(NGFR-COLIAI-MPO)-GAA-UM PH-GHC-TK1-GALK-qter. Using chromosome-mediated gene transfer, we have also regionally localized the random probes D17S6 to D17S19 on chromosome 17.

Abstract
The colony-stimulating factors regulate growth, differentiation, and function of blood cells. The effect of granulocyte colony-stimulating factor (G-CSF) on myeloid leukemias is unique among colony-stimulating factors in driving the leukemic cells from a self-renewing malignant state to a mature differentiated phenotype with the concomitant loss of tumorigenicity. This property of G-CSF has led to suggestions that its absence is responsible for lack of differentiation of leukemic cells and that the therapeutic administration of G-CSF could reverse this defect and result in a cure for leukemia. Here we show that the gene coding for human G-CSF is localized to chromosome 17, bands q11.2-21. The translocation of the long arm of chromosome 17 at q12-21 to chromosome 15 is a specific abnormality occurring in a high proportion of, if not all, patients with acute promyelocytic leukemia, a disease characterized by undifferentiated myeloid cells and a dismal prognosis. Abnormalities of the regulation of a specific differentiation factor gene mediated by a specific chromosomal rearrangement may be directly implicated in the pathogenesis of human leukemia.

Abstract
Hybridization of probe pDP151 (locus D15S2) to genomic human DNAs digested with EcoRI revealed allelic restriction fragments 9 and 11 kilobase-pairs (kb) in length. Hybridization of pDP151 to EcoRI-digested DNAs from 21 Chinese hamster X human hybrid cell clones containing different subsets of human chromosomes demonstrated cosegregation of the 9 and 11 kb EcoRI fragments with human chromosome 15. D15S2 and two other polymorphic loci previously mapped to chromosome 15--D15S1 and D15S6--were localized to specific regions on human chromosome 15. Eight Chinese hamster X human somatic cell hybrid clones derived from a human donor heterozygous for a balanced translocation between chromosomes 15 and 22 [t(15;22)(q14;q13.3); Oliver et al, Cytogenet Cell Genet 22:503-510, 1978] were studied. After digestion of human and hybrid DNAs with HindIII and Southern blotting, pDP151 (D15S2) and pMS1-14 (D15S1) hybridized to fragments of 4 and 4.5 kb, respectively. Further, pMS1-14 (D15S1) and p9-1a (D15S6) hybridized to EcoRI fragments of 3.5 and 3.2 kb. All fragments cosegregated with the der(22) derivative chromosome containing region 15q14----15qter. In situ hybridization of these probes to normal human chromosomes mapped the corresponding loci with greater precision: D15S1 to 15q15----15q21, D15S2 to 15q15----15q22, and D15S6 to 15q22----15q24.

Abstract
The technique of premature chromosome condensation involves the fusion of mitotic cells with interphase cells resulting in the immediate condensation of the interphase chromatin into discrete chromosome units, the prematurely condensed chromosomes (PCC). The ability to visualize the interphase chromosomes of bone marrow and blood cells by this technique has proved useful in the study of human leukemia. This article describes how the PCC technique has been used to predict clinical outcome as well as gain insight into the biology of leukemia.

Abstract
Recent studies have demonstrated that the cellular tumour antigen p53 (ref. 1) can complement activated ras genes in the transformation of rat fibroblasts, suggesting that the gene encoding p53 may act as an oncogene. Here, by using in situ chromosomal hybridization, we have mapped the p53 gene to human chromosome 17, at bands 17q21-q22, the region containing one of the breakpoints in the translocation t(15;17) (q22;q21) associated with acute promyelocytic leukaemia (APL). Hybridization of p53 and erb-A (17q11-q12) probes to malignant cells from three APL patients indicated that the p53 gene is translocated to chromosome 15 (15q+), whereas erb-A remains on chromosome 17. Analysis of variant translocations demonstrates that the 15q+ chromosome contains the conserved junction, suggesting a role for p53 in the pathogenesis of APL. However, rearrangements of the p53 gene were not detected on Southern blotting of DNA from leukaemic cells of four APL patients with t(15;17).

Abstract
Using in situ hybridization, c-erbA1 has been mapped immediately distal to the translocation breakpoint on chromosome 17 in fibroblasts with a karyotype 46,XX, t(15;17)(q22;q11). Previous work has shown that c-erbA1 is proximal to the translocation breakpoint on chromosome 17 in the t(15;17)(q22;q12-21) in acute promyelocytic leukaemia. The oncogene can therefore be localized to the region of chromosome 17 between the breakpoints in 17q11 and 17q12-21.

Abstract
Cytogenetic analysis was carried out on peripheral blood cultures from seven patients with acute promyelocytic leukaemia (APL-M3). A reciprocal 15;17 chromosome translocation, t(15q+;17q-), was found in all cases, and the breakpoints estimated to be 15q22 and 17q12-21. In addition to the t(15q+;17q-), trisomy 10 was found in 50% of cells analysed in one case. These results suggest that the 15;17 chromosome translocation may be observed in most cases of APL where the leukaemic cells are cultured before cytogenetic analysis is performed. The use of conditioned media in the culture of leukaemic cells is also described.

Abstract
The human germ-line position of c-erb-A, the cellular counterpart of v-erb-A, has been determined by in situ molecular hybridization of a 3H-labeled c-onc gene probe to meiotic pachytene chromosomes. Both v-erb-A and v-erb-B are the v-onc genes that are associated with induction of sarcoma and erythroblastosis in chicken by the avian erythroblastosis virus, a rapidly transforming RNA tumor virus. The position of c-erb-A, determined here to be at 17q21.33-q22, is in the same region of chromosome 17 in which a nonrandom break occurs in the generation of t(15;17), a translocation commonly seen in acute promyelocytic leukemia.

Abstract
BXH-2 recombinant inbred (RI) mice produce high titers of B-ecotropic murine leukemia virus beginning early in life and have a high incidence of non-T-cell leukemias that occur before 1 year of age. The leukemias that develop are in some cases associated with hind limb paralysis. In addition, a dualtropic mink cell focus-forming virus has been isolated from leukemic cells of BXH-2 mice. Immunological and cytochemical characterization of the BXH-2 leukemias showed that they are of the myeloid lineage. To assess the oncogenicity of the BXH-2 viruses, newborn mice of several BXH RI strains were inoculated at birth with biologically cloned B-ecotropic or mink cell focus-forming murine leukemia virus. These studies demonstrated that the B-ecotropic virus can induce myeloid leukemias in other BXH RI strains, whereas the dualtropic mink cell focus-forming isolates were nononcogenic in the strains tested. DNA-DNA reassociation analysis indicated that the organotropism of the B-ecotropic murine leukemia virus is confined to lymphoid tissues. Southern analysis of tumor DNAs showed that there was amplification of ecotropic virus-specific sequences in BXH-2 myeloid tumors and in all leukemias induced in other BXH RI strains by inoculation of the BXH-2 B-ecotropic virus. Although B-ecotropic virus is expressed in central nervous tissues of paralyzed BXH-2 mice, we were unable to induce the disorder in several BXH RI strains inoculated intracranially at birth with either the B-ecotropic or dualtropic virus. These results suggest that the paralysis that occurs in BXH-2 mice is due to the infiltration of leukemic cells into the central nervous system.

Abstract
A cloned 15 kb genomic fragment from the human alpha 1(I) collagen gene (COL1A1) has been used as a probe on restriction digests of DNA from human-mouse somatic cell hybrids. Positive results on hybrids containing chromosome 17 as their only karyotypically visible human material confirm the assignment of this gene to chromosome 17. Hybrids which contain fragments of chromosome 17 are used to confirm the localization to 17q21-qter.

Abstract
The human c-ab1 oncogene maps within the region (q34-qter) of chromosome 9 which is translocated to chromosome 22, the Philadelphia (Ph') chromosome, in chronic myelocytic leukaemia (CML). The position of the Ph' chromosomal break point is shown to be variable and, in one CML patient, has been localized immediately 5' of, or within, the c-ab1 oncogene. A DNA restriction fragment corresponding to this site has been molecularly cloned and shown to represent a chimaeric fragment of DNA from chromosomes 9 and 22.
