Abstract
PURPOSE/OBJECTIVE(S) Radiation dermatitis (RD) is common among women undergoing breast and chest wall radiotherapy (RT); however, existing scales to assess the severity of RD are subjective and do not account for variability in skin of color (SOC). For instance, the Common Terminology Criteria for Adverse Events (CTCAE) criteria do not include hyperpigmentation in the grading scale. There is data indicating worse RD in African American and Hispanic patients; however, the rate and severity in SOC remains unknown given the lack of data using objective measures of RD. Spectrophotometry is one method to quantify the appearance of color by measuring spectral characteristics without the bias associated with subjective clinical scoring. We present a phase I prospective non-therapeutic clinical trial to objectively define SOC at baseline and evaluate spectrophotometric skin changes during and after breast or chest wall RT in parallel with physician-graded RD using CTCAE criteria. We hypothesize that there will be greater discrepancy between physician graded RD and objective measures of RD in patients with SOC in whom hyperpigmentation will be undercaptured by physician-grading. This is the first study intending to correlate SOC with objective changes after RT as a reliable indicator of RD. We offer a novel system for evaluating RD that is applicable to SOC. MATERIALS/METHODS A total of 60 patients with localized breast cancer (stage 0-III) undergoing conventional whole breast or chest wall RT (50Gy/ 25 fx), hypofractionated whole breast RT (40.5Gy/15 fx) or ultrahypofractionated partial breast RT (6Gy x5), with or without regional nodal RT were enrolled. 3 skin color readouts using the Commission International de l'Eclairage 3D color system (l*, a*, b*) were measured within the radiation field using a spectrophotometer at baseline, once weekly during RT, 10 days post RT, 4 weeks and 12 months post RT. The spectrophotometer is a non-invasive, hand-held device that is used in the clinic room with no additional equipment or setup requirements. Data is automatically exported to a spreadsheet organized by timepoint and patient. The l* axis is a gray scale (0 = black, 100 = white) correlating with skin pigmentation and the a* axis describes red and green values correlating with erythema. The primary objective is to evaluate the changes from baseline in skin color readouts in the quadrant of tumor location during and after RT based on fractionation. The secondary objective is to evaluate changes within and across groups defined by baseline skin color. Exploratory objectives include evaluating the association of baseline color readouts and changes after RT with acute and late grade > 2 clinician-rated skin and subcutaneous tissue effects according to the CTCAE, v5.0, physician graded cosmesis and clinical interventions to treat RD, such as use of topical steroids and oral analgesics. As of January 2023, we have enrolled 100% of the planned patients. RESULTS To be determined. CONCLUSION To be determined. Clinical Study Identifier: S22-00192.

Abstract
Abstract
BACKGROUND
Diffuse gliomas are highly aggressive brain tumors that invariably relapse despite treatment with chemo- and radiotherapy. Treatment with alkylating chemotherapy can drive tumors to develop a hypermutator phenotype. In contrast, the genomic effects of radiation therapy (RT) remain largely unknown.
MATERIAL AND METHODS
We analyzed the mutational spectra following treatment with RT in whole genome or exome sequencing data from 190 paired primary-recurrent gliomas from the Glioma Longitudinal Analysis (GLASS) dataset and 3693 post-treatment metastatic tumors from the Hartwig Medical Foundation (HMF).
RESULTS
We identified a significant increase in the burden of small deletions following radiation therapy that was independent of other factors (P = 3e-03, multivariable log-linear regression). These novel deletions demonstrated distinct characteristics when compared to pre-existing deletions present prior to RT-treatment and deletions in RT-untreated tumors. Radiation therapy-acquired deletions were characterized by a larger deletion size (GLASS and HMF, P = 1.5e-04 and P = 6e-16, respectively; Mann-Whitney U test), an increased distance to repetitive DNA elements (P < 2.2e-16, Kolmogorov-Smirnov test) and a lack of microhomology at breakpoints (P = 6.6e-05, paired Wilcoxon signed-rank test). Furthermore, mutational signature analysis confirmed the distinct genomic characteristics of RT-associated deletions when compared to deletions arising via homologous recombination deficiency or microsatellite instability.
These observations suggested that canonical non-homologous end joining (c-NHEJ) was the preferred pathway for DNA double strand break repair of RT-induced DNA damage. Furthermore, RT resulted in frequent chromosomal deletions and significantly increased frequencies of CDKN2A homozygous deletions in IDHmut glioma (P= 1.9e-05, Fisher’s exact test). Finally, a high burden of RT-associated deletions was associated with worse clinical outcomes (GLASS and HMF, P = 3.4e-02 and P < 1e-04, respectively; log-rank test).
CONCLUSION
Our results collectively suggest that effective repair of RT-induced DNA damage is detrimental to patient survival and that inhibiting c-NHEJ may be a viable strategy for improving the cancer-killing effect of radiotherapy. Furthermore, CDKN2A homozygous deletion at recurrence may be leveraged as a promising clinical biomarker of RT-resistance in IDHmut glioma. Taken together, the identified genomic scars as a result of RT reflect a more aggressive tumor with increased levels of resistance to follow up treatments.

Abstract
Glioblastoma (GBM) is a primary brain cancer that contains populations of stem-like cancer cells (GSCs) that home to specialized perivascular niches. GSC interactions with their niche influence self-renewal, differentiation and drug resistance, although the pathways underlying these events remain largely unknown. Here, we report that the integrin αvβ8 and its latent transforming growth factor β1 (TGFβ1) protein ligand have central roles in promoting niche co-option and GBM initiation. αvβ8 integrin is highly expressed in GSCs and is essential for self-renewal and lineage commitment in vitro. Fractionation of β8high cells from freshly resected human GBM samples also reveals a requirement for this integrin in tumorigenesis in vivo. Whole-transcriptome sequencing reveals that αvβ8 integrin regulates tumor development, in part, by driving TGFβ1-induced DNA replication and mitotic checkpoint progression. Collectively, these data identify the αvβ8 integrin-TGFβ1 signaling axis as crucial for exploitation of the perivascular niche and identify potential therapeutic targets for inhibiting tumor growth and progression in patients with GBM.

Abstract
LBA2000 Background: Formalin-fixed, paraffin embedded GBM tumor tissue, adequate for conventional MGMT methylation analyses, was required for entry onto the RTOG 0525 clinical trial. Methods: Four prognostic biomarkers were evaluated on a training set of 220 retrospectively obtained GBM samples, consisting of IDH1 mutation, the glioma-CpG island methylator phenotype (G-CIMP), a microarray-based mRNA panel and a novel MGMT promoter methylation assay. For each biomarker, 2 (IDH1 and mRNA) or 3 subgroups (G-CIMP and MGMT) were defined based on associations with overall survival. All combinations (36 possible) of each of the 4 biomarker-derived subgroups were then defined and compared with survival data and then consolidated into 4 risk groups. Once created in the training set, this model was applied to the RTOG 0525 samples (n=763) for external validation. Results: Application of the molecular risk classification to RTOG 0525 samples (left table) showed a highly significant survival association (p<0.001). When compared to the recursive partitioning analysis (RPA, table on right), this composite molecular classifier better identified patients with long term survival and appears to improve resolution by revealing an additional distinct risk group. The molecular classifier was prognostic in each of the treatment arms individually. Conclusions: Four distinct biomarkers or biomarker panels were tested in GBM. These biomarkers were compared with clinical outcome in a training set to optimize a method to combine them into a classifier. This classifier was then validated on a large sample set from a large phase III clinical trial. This composite panel may represent an improvement over the existing RPA with respect to risk stratification of patients for GBM. Additionally, it has the potential to impact future clinical trial designs and provide enhanced opportunities for personalization of therapy for GBM. Support: NCI U10 CA2121661, U10 CA37422, P50 CA127001. [Table: see text]

Abstract
BACKGROUND Several lines of evidence es tablish that chromosome band 1p36 is frequently deleted in neuroblastoma primary tumors and cell lines, suggesting that a tumor suppressor gene within this region is involved in the development of this tumor. PROCEDURE We analyzed the status of 1p36 in primary neuroblastomas and cell lines to define the region of consistent rearrangement. RESULTS Loss of heterozygosity (LOH) studies of primary neuro blastomas identified allelic loss in 135 of 503 tumors (27%), with the smallest region of overlap (SRO) defined distal to D15214 (1p36.3). No homozygous deletions were detected at 120 loci mapping to 1p36.1-p36.3 in a panel of 46 neuroblastoma cell lines. A recently identified patient with neuroblastoma was found to have a constitutional deletion within 1p36.2-p36.3, and this deletion, when combined with the LOH results, defined a smaller SRO of one megabase within 1p36.3. We constructed a comprehensive integrated map of chromosome 1 containing 11,000 markers and large-insert clones, a high-resolution radiation hybrid (RH) map of 1p36, and a P1-artificial chromosome (PAC) contig spanning the SRO, to further characterize the region of interest. Over 768 kb (75%) of the SRO has been sequenced to completion. Further analysis of distal 1p identified 113 transcripts localizing to 1p36, 21 of which were mapped within the SRO. CONCLUSION This analysis will identify suitable positional candidate transcripts for mutational screening and subsequent identification of the 1p36.3 neuroblastoma suppressor gene.

Abstract
BACKGROUND MYCN amplification and overexpression occurs in 25% of neuroblastomas and independently predicts for poor prognosis disease, an effect thought to be mediated by its role as a transcriptional activator of growth promoting genes. However, in many mammalian cells, deregulated expression of MYC family genes (including MYCN) induces apoptosis. We hypothesized that BIN1, a MYC interacting protein capable of inducing apoptosis, may be an important regulator of MYCN in neuroblastoma. RESULTS BIN1 expression was found to be reduced in MYCN-amplified cell lines. Further, forced expression of BIN1 markedly reduced colony formation in MYCN-amplified, but not single-copy, cell lines. This effect appeared to be caused by an increase in apoptosis, and was augmented by serum deprivation and concurrent cytotoxic drug therapy in cell culture CONCLUSION BIN1 inactivation may be necessary for MYCN overexpression to lead to cellular proliferation rather than programmed cell death in neuroblastomas with MYCN amplification.

Abstract
BACKGROUND Deletion of the distal short arm of chromosome 1 occurs frequently in neuroblastoma. In addition, neuroblastoma has been described in children with constitutional deletions within 1p36, supporting the existence of one or more neuroblastoma suppressor genes within this region. PROCEDURE We have pursued a 1p36 tumor suppressor gene identification strategy that has included deletion mapping of 566 primary neuroblastomas and 46 neuroblastoma-derived cell lines, and have determined the parental origin of the deleted 1p homologue in 44 cases to determine whether there is evidence for genomic imprinting within this region. RESULTS AND CONCLUSIONS We have identified a 1-Mb consensus region of deletion within 1p36.3 defined by primary tumor deletions, constructed a physical map of the region that is being sequenced to completion, and have identified and prioritized candidate genes within this region for further analyses.

Abstract
Several human malignancies frequently exhibit deletions or rearrangements of the distal short arm of chromosome 1 (1p36), and a number of genetic diseases also map to this region. The carbonic anhydrase (CA6) and alpha-enolase (ENO1) genes, previously mapped to 1p36, were physically linked in yeast- and P1-artificial chromosome (YAC and PAC) contigs. PACs from the contig were mapped to 1p36.2 by fluorescence in situ hybridization. The ESTs D1S2068, D1S274E, D1S3275, and stSG4370 were also placed in the same contig. The physical map was integrated with the genetic map of chromosome 1 by assignment of genetic markers D1S160, D1S1615, and D1S503 to the contig. Sequencing of the EST clone representing D1S274E indicated that it was derived from the same transcript as D1S2068E and corresponded to the SLC2A5 (GLUT5) gene, previously assigned to 1p31. Reassignment of SLC2A5 to 1p36.2 was confirmed by somatic cell and radiation hybrid mapping panels and was consistent with previous EST mapping data. Sequencing of the EST clone for D1S274E revealed the presence of intronic sequences, suggesting that the clone was derived from an unprocessed message. The presence of unprocessed and/or alternatively spliced EST clones has potential ramifications for EST-based genomic projects. This information should facilitate the mapping of tumor suppressor and genetic disease loci that have been localized to this region.

Abstract
PURPOSE To determine the independent prognostic significance of 1p36 loss of heterozygosity (LOH) in a representative group of neuroblastoma patients. PATIENTS AND METHODS Diagnostic tumor specimens from 238 patients registered onto the most recent Children's Cancer Group phase III clinical trials were assayed for LOH with 13 microsatellite polymorphic markers spanning chromosome band 1p36. Allelic status at 1p36 was correlated with other prognostic variables and disease outcome. RESULTS LOH at 1p36 was detected in 83 (35%) of 238 neuroblastomas. There was a correlation of 1p36 LOH with age at diagnosis greater than 1 year (P = .026), metastatic disease (P<.001), elevated serum ferritin level (P<.001), unfavorable histopathology (P<.001), and MYCN oncogene amplification (P<.001). LOH at 1p36 was associated with decreased event-free survival (EFS) and overall survival (OS) probabilities (P<.0001). For the 180 cases with single-copy MYCN, 1p36 LOH status was highly correlated with decreased EFS (P = .0002) but not OS (P = .1212). Entering 1p36 LOH into a multivariate regression model suggested a trend toward an independent association with decreased EFS (P = .0558) but not with decreased OS (P = .3687). Furthermore, allelic status at 1p36 was the only prognostic variable that was significantly associated with decreased EFS in low-risk neuroblastoma patients (P = .0148). CONCLUSION LOH at 1p36 is independently associated with decreased EFS, but not OS, in neuroblastoma patients. Determination of 1p36 allelic status may be useful for predicting which neuroblastoma patients with otherwise favorable clinical and biologic features are more likely to have disease progression.

Abstract
Comprehensive representations of human chromosomes combining diverse genomic data sets, localizing expressed sequences, and reflecting physical distance are essential for disease gene identification and sequencing efforts. We have developed a method (CompView) for integrating genomic information derived from available cytogenetic, genetic linkage, radiation hybrid, physical, and transcript-based mapping approaches. CompView generates chromosome representations with substantially higher resolution, coverage, and integration than current maps of the human genome. The CompView process was used to build a representation of human chromosome 1, yielding a map with >13,000 unique elements, an effective resolution of 910 kb, and a marker density of 50 kb. CompView creates comprehensive and fully integrated depictions of a chromosome's clinical, biological, and structural information.

Abstract
Neuroblastoma is a pediatric malignancy of the sympathetic nervous system and is frequently characterized by genetic aberrations (including aneuploidy, chromosomal deletions, translocations, and gene amplification) that suggest inherent genomic instability. Mutations in mismatch repair (MMR) genes have been associated with genomic instability in several human cancers, such as those of the hereditary nonpolyposis colorectal cancer (HNPCC) syndrome. In these cases, replication errors at microsatellite repeats lead to microsatellite instability (MSI) and mutagenesis. In neuroblastoma, we and others have detected MSI infrequently when analyzed at di- or tetranucleotide repeat polymorphic markers. More recently, however, mutations in the MMR gene GTBP/hMSH6 have been associated with a limited phenotype of instability at mononucleotide repeats only (e.g., polyadenine tracts). Furthermore, mononucleotide repeats appear to be common downstream targets of MSI-related mutagenesis and are present in the transforming growth factor-beta receptor-II gene (TGF beta RII), the BAX proapoptosis gene, and the insulin-like growth factor II receptor gene (IGFIIR) frequently in tumors arising in HNPCC kindreds. Therefore, we analyzed 46 matched normal and tumor DNAs representing all clinical stages of neuroblastoma with the use of five polymorphic mononucleotide repeat markers to assess for MSI at mononucleotide repeats. Only one tumor (2%) demonstrated mononucleotide repeat instability, and the instability was at a single locus. We conclude that MSI, including mononucleotide repeat instability, is infrequent in human neuroblastoma, and therefore defects in DNA mismatch repair are not responsible for the genomic instability seen in this neoplasm.

Abstract
Meningioma is a common tumor of the central nervous system. Deletions of the short arm of chromosome 1 (1p) are the second most commonly observed chromosomal abnormality in these tumors. Here, we analyzed tumor and normal DNAs from 157 meningioma patients using PCR-based polymorphic loci. Loss of heterozygosity (LOH) for at least one informative marker on 1p was observed in 54 cases (34%), whereas LOH on 1q occurred in only 9 cases (8%). High-resolution deletion mapping defined a consensus region of deletion flanked distally by D1S2713 and proximally by D1S2134, which spans 1.5 cM within 1p32. LOH in this region has also been observed in several other malignancies, suggesting the presence of a tumor suppressor gene or genes that are important for several types of cancer. Statistical analysis revealed that 1p LOH was associated with chromosome 22 deletions and with abnormalities of the NF2 gene in meningioma. In addition, unlike other clinical and molecular characteristics, only 1p LOH was shown to be significantly associated with recurrence-free survival.

Abstract
Human Krüppel-related 3 (HKR3) is a zinc finger gene that maps within chromosome subbands 1p36.2-.3, a region postulated to contain a tumour suppressor gene associated with advanced neuroblastomas. Genomic clones of HKR3 were isolated from a P1 library and physically mapped to within 40 kb of D1S214 at 1p36.3. The gene is ubiquitously expressed in human tissues, but especially high levels are present in human fetal and adult nervous tissues. Hemizygous deletion of HKR3 in a lymphoblastoid cell line derived from a neuroblastoma patient with a constitutional 1p36 interstitial deletion and in the neuroblastoma cell line SK-N-AS, which also has a small interstitial 1p36 deletion, has been observed. Allelic loss at D1S214 in 15/15 informative primary neuroblastoma specimens with 1p36 deletions has also been observed. In a panel of 16 neuroblastoma cell lines, no gross genomic DNA rearrangements were noted, the gene was always expressed (albeit at variable levels) and there was no evidence for truncating mutations. Furthermore, there were no mutations detected in the zinc finger coding region in four neuroblastoma cell lines with 1p deletions analysed by direct sequence analysis. We conclude that HKR3 is a novel zinc finger gene that maps to a region of the genome commonly rearranged or deleted in neuroblastoma and other human cancers.

Abstract
Neuroblastoma has several clinical and molecular genetic parallels with the other paediatric embryonal tumours, such as retinoblastoma, including a hereditary form of the disease. We hypothesised that neuroblastoma susceptibility is due to germline mutations in a tumour suppressor gene and that this predisposition gene may be involved in sporadic neuroblastoma tumorigenesis as well. We therefore aimed to localise the familial neuroblastoma predisposition gene by linkage analysis in neuroblastoma kindreds. Eighteen families segregating for neuroblastoma were ascertained for candidate locus linkage analysis. Although many of the 49 affected individuals in these families were diagnosed as infants with multifocal primary tumours, there was marked clinical heterogeneity. We originally hypothesised that familial neuroblastoma predisposition would map to the telomeric portion of chromosome band 1p36, a genomic region likely to contain a sporadic neuroblastoma suppressor gene. However, neuroblastoma predisposition did not map to any of eight polymorphic markers spanning 1p36.2-.3 in three large kindreds. In addition, there was strong evidence against linkage to two Hirschsprung disease susceptibility genes (RET and EDNRB), a condition that can cosegregate with neuroblastoma as in one of the kindreds tested here. We conclude that the neuroblastoma susceptibility gene is distinct from the 1p36 neuroblastoma suppressor and two of the currently identified Hirschsprung disease susceptibility genes.

Abstract
Cellular, cytogenetic, and molecular evidence indicates that chromosome band 1p36 is often deleted in neuroblastoma cell lines and tumours, suggesting the presence of one or more tumour suppressor genes in this region. We used a multifaceted approach to analyse the commonly deleted region, 28 distal 1p-specific polymorphic loci were used to detect loss of heterozygosity (LOH) in a panel of primary neuroblastoma tumours. Thirty-two of 122 tumours (26%) demonstrated LOH at three or more loci. In addition, a patient with a constitutional deletion of 1p36.2-.3 and two neuroblastoma cell lines with 1p36 abnormalities were characterised by FISH. When combined with the LOH data, a single consensus region of deletion was defined proximally by PLOD and distally by D1S80, a region spanning approximately five megabases. Several proposed candidate tumour suppressor genes, including ID3, CDC2L1, DAN, PAX7, E2F2, TNFR2 and TCEB3, map outside of this region; however, the transcription factor HKR3 cannot be excluded. LOH for 1p is correlated with adverse clinical and biological features and a poor prognosis, but 1p LOH is not an independent predictor of overall survival. To identify additional candidate genes, an integrated physical map of 1p35-36 is being constructed. The current map includes 445 polymerase chain reaction (PCR)-formatted markers and 608 YACs. This map will help identify region-specific transcripts by direct selection and sequencing.

Abstract
The distal short arm of human chromosome 1 (1p) is rearranged in a variety of malignancies, and several genetic diseases also map to this region. We have constructed an integrated transcript map to precisely define the positions of genes and expressed sequence tags (ESTs) previously mapped to 1p35-p36, a region spanning approximately 40 Mb. To anchor the integrated map, a framework genetic map was constructed with 24 genetic markers and a marker order of 1000:1 odds, yielding an average resolution of 2.8 cM. An additional 106 genetic markers were localized relative to the framework genetic map. To place markers more precisely within 1p35-p36, a chromosome 1-specific, radiation-reduced hybrid (RH) panel was created. Individual DNA fragments of the RH panel were identified and ordered by PCR with the framework genetic map. A total of 250 markers, including 142 genes and ESTs, were mapped by PCR against the RH panel. The map has an observed resolution of 800 kb, and the results closely match and more precisely define previous mapping information for most markers. This map will help to identify candidate genes for genetic diseases mapping to distal 1p and is fully integrated with existing genetic and RH maps of the human genome.

Abstract
Ror1 is an orphan cell surface receptor with strong homology to the tyrosine kinase domain of growth factor receptors, in particular the Trk family. Southern blot analysis of genomic DNA from somatic cell hybrids revealed that Ror1 is located on chromosome 1. We have mapped the Ror1 gene to chromosome 1p12-p32 using PCR on a somatic cell hybrid panel that subdivides chromosome 1p. We have further localized the gene to chromosome 1p31-p32 by fluorescence in situ hybridization using a PAC clone that contains the Ror1 gene.

Abstract
Mouse eck, a member of the EPH gene family, has been mapped to mouse chromosome 4. The syntenic relationship between this chromosome and human chromosome 1 suggests that the human ECK gene maps to the distal short arm of human chromosome 1 (1p). Since this region is frequently deleted or altered in certain tumors of neuroectodermal origin, it is important to define the specific chromosomal localization of the human ECK gene. PCR screening of a rodent-human somatic cell hybrid panel by ECK-specific primers showed that ECK is indeed localized to human chromosome 1. Additional PCR screening of a regional screening panel for chromosome 1p indicated that ECK is localized to 1p36, distal to FUCA1. Furthermore, fluorescence in situ hybridization analysis with an ECK-specific P1 clone showed that ECK maps proximal to genetic marker D1S228. Taken together, the data suggest that ECK maps to 1p36.1, a region that is frequently deleted in neuroblastoma, melanoma, and other neuroectodermal tumors.

Abstract
One of the most important prognostic factors in neuroblastoma is amplification of the MYCN gene, which is strongly associated with advanced stages of disease and a poor prognosis. Although the MYCN amplicon sometimes spans more than 1 Mb, no other consistently expressed sequences from the MYCN amplicon have been reported. However, DDX1, a gene encoding a DEAD box protein, was recently mapped to chromosome 2p24 and is frequently co-amplified with MYCN. Therefore, we performed genomic mapping with YACs to determine the physical relationship between DDX1 and MYCN, and whether DDX1 was contained within the core region of amplification. Based on YAC restriction mapping and content analysis, DDX1 maps 340 kb 5' of MYCN, outside the core domain of consistent amplification. Interestingly, we also determined by sequence analysis and detailed restriction mapping that G21, previously isolated as a 'neuroblastoma-specific' cDNA clone from an MYCN amplicon, is a partial cDNA of DDX1. Our data confirm that DDX1 is amplified in some but not all MYCN-amplified tumors, and that it is rearranged in other cases. This suggests that the co-amplification of DDX1 is due to its proximity to MYCN.

Abstract
Familial predisposition to neuroblastoma, a common embryonal cancer of childhood, segregates as an autosomal dominant trait with high penetrance. It is therefore likely that neuroblastoma susceptibility is due to germ line mutations in a tumor suppressor gene. Cytogenetic, functional, and molecular studies have implicated chromosome band 1p36 as the most likely region to contain a suppressor gene involved in sporadic neuroblastoma tumorigenesis. We now demonstrate that neuroblastoma predisposition does not map to any of eight polymorphic markers spanning 1p36 by linkage analysis in three families. In addition, there is no loss of heterozygosity at any of these markers in tumors from affected members of these kindreds. Furthermore, there is strong evidence against linkage to two Hirschsprung disease (a condition that can cosegregate with neuroblastoma) susceptibility genes, RET and EDNRB. We conclude that the neuroblastoma susceptibility gene is distinct from the 1p36 tumor suppressor and the currently identified Hirschsprung disease susceptibility genes.

Abstract
The Krüppel-type zinc finger proteins are members of a conserved family of transcription factors that are important in developmental regulation. Altered expression of several of these proteins has been implicated in human diseases, including cancer. We report the cloning, mapping, and characterization of the zinc finger gene Human Krüppel-Related 3 (HKR3). Genomic clones of HKR3 were isolated from a P1 library and localized to human chromosome subband 1p36.3 by human-rodent somatic cell hybrid mapping and fluorescence in situ hybridization. The gene was physically mapped to within 40 kb of D1S214 by YAC content and long-range restriction mapping. HKR3 spans 9.5 kb of genomic DNA and is contained in 11 exons. Sequencing defined each of the exon/intron splice site junctions and identified a CpG island in the 5' region of the gene. HKR3 is ubiquitously expressed in human tissues as at least two major transcripts, the shorter of which excludes a conserved finger-associated box and a putative acidic activation domain contained in the full-length transcript. HKR3 is a novel zinc finger gene that maps to a region of the genome commonly rearranged or deleted in human cancers.

Abstract
The tumor necrosis factor receptor 2 (TNFR2) gene localizes to 1p36. 2, a genomic region characteristically deleted in neuroblastomas and other malignancies. In addition, TNFR2 is the principal mediator of the effects of TNF on cellular immunity, and it may cooperate with TNFR1 in the killing of nonlymphoid cells. Therefore, we undertook an analysis of the genomic structure and precise physical mapping of this gene. The TNFR2 gene is contained on 10 exons that span 26 kb. Most of the functional domains of TNFR2 are encoded by separate exons, and each of the repeats of the extracellular cysteine-rich domain is interrupted by an intron. The genomic structure reveals a close relationship to TNFR1, another member of the TNFR superfamily. Based on electrophoretic analysis of yeast artificial chromosomes, TNFR2 maps within 400 kb of the genetic marker D1S434. In addition, we have identified a new polymorphic dinucleotide repeat within intron 4 of TNFR2. The genetic sequence information and exon-intron boundaries we have determined will facilitate mutational analysis of this gene to determine its potential role in neuroblastoma, as well as in other cancers with characteristic deletions or rearrangements of 1p36.

Abstract
By screening a human fetal brain cDNA expression library using a monoclonal antiphosphotyrosine antibody and by 5' RACE procedures, we have isolated overlapping cDNAs encoding a receptor-type tyrosine kinase belonging to the EPH family, DRT (Developmentally Regulated EPH-related Tyrosine kinase gene). The DRT gene is expressed in three different size transcripts (i.e. 4, 5 and 11 kb). DRT transcripts are expressed in human brain and several other tissues, including heart, lung, kidney, placenta, pancreas, liver and skeletal muscle, but the 11 kb DRT transcript is preferentially expressed in fetal brain. Steady-state levels of DRT mRNA in several tissues, including brain, heart, lung and kidney, are greater in the midterm fetus than those in the adult. DRT transcripts are detectable at low levels in a human teratocarcinoma cell line (NTera-2), but its expression is greatly increased after the NTera-2 cells are induced to become postmitotic neurons (NTera-2N) by retinoic acid treatment. These data suggest that DRT plays a part in human neurogenesis. A large number of tumor cell lines derived from neuroectoderm express DRT transcripts, including 12 neuroblastomas, two medulloblastomas, one primitive neuroectodermal tumor and six small cell lung carcinomas (SCLC). Interestingly, several neuroblastoma cell lines with 1p deletion and one SCLC cell line express DRT transcripts of aberrant size (i.e. 3, 6 and 8 kb) in addition to those found in normal tissues. We mapped the DRT gene to human chromosome 1p35-1p36.1 by PCR screening of human-rodent somatic cell hybrid panels and by fluorescence in situ hybridization. As the distal end of chromosome 1p is often deleted in neuroblastomas and altered in some cases in SCLCs, these chromosomal abnormalities may have resulted in the generation of aberrant size transcripts. Thus, the DRT gene may play a part in neuroblastoma and SCLC tumorigenesis.

Abstract
We analyzed 156 primary neuroblastoma tumor samples for loss of heterozygosity at the distal short arm of chromosome 1 (1p LOH). We also compared 1p LOH with known clinical and genetic prognostic variables as well as patient outcome. 1p LOH was detected in 30 of 156 tumors (19%) and was strongly associated with adverse clinical and biological features. 1p LOH was also strongly predictive of a poor outcome in univariate analyses (estimated 4-year survival, 32 +/- 10% SE versus 76 +/- 5% SE; P < 0.001). However, the prognostic value of 1p LOH was equivocal when stratified for amplification of the MYCN oncogene (P = 0.16). We conclude that 1p LOH is an important component of a pattern of genetic abnormalities in neuroblastoma associated with an aggressive clinical course.

Abstract
Mutations of CDKN2 have been found recently in melanoma and many other tumor types. Neuroblastoma shares with melanoma a neuroectodermal origin and a high incidence of deletions of the short arm of chromosome 1. Therefore, we analyzed 18 primary neuroblastomas and 9 tumor-derived cell lines for mutations in CDKN2. We used PCR-single-strand conformation polymorphism to examine exons 1 and 2 of the CDKN2 gene for mutations, but none were detected. Furthermore, no homozygous deletions were detected and there was no loss of heterozygosity at the closely linked IFNA locus. We conclude that disruption of the CDKN2 gene is not required for malignant transformation of human neuroblastomas.
