Abstract
INTRODUCTION. Over the years the field of genetics has advanced significantly. Following the polymerase chain reaction and mass sequencing techniques, the array-CGH technique (comparative genomic hybridization) has helped to improve genetic procedures. A resolution of up to 200 kb is currently being accomplished in the human genome. CASE REPORTS. We report the case of two sisters with delays in developmental milestones and a characteristic phenotype with normal results from initial studies of the karyotype and subtelomeric regions. Array-CGH was later used to detect a deletion and duplication that were different in each of the sisters, this being the result of a balanced paternal translocation. In the two cases, despite being the result of the same translocation, the genetic and phenotype expression were different. CONCLUSIONS. The precision achieved by means of array-CGH is making it possible to establish a correlation between minimum gains or losses of the genome and the clinical features. Chromosome 3 codes for genes that play a fundamental role in neurological development (contactins, neurotransmitter modulator proteins, etc.) and chromosome 10 codes for proteins involved in apoptosis and proteins regulating transcription. In the literature there have been reports of chromosome 3 deletion syndrome and monosomy 10. Likewise, there are also descriptions of rearrangements between these chromosomes in individuals from the same family. Nevertheless, we describe two cases of a family with a micro-deletion and an inverted microduplication, detected by means of array-CGH, that have not been reported to date. This technique can provide a diagnostic and prognostic approximation as regards development and offer genetic counselling.

Abstract
The ETV6/GOT1 fusion, resulting from t(10;12) (q24;p13), has been recently described in a myelodysplastic syndrome. We reported a second case of t(10;12)-positive myelodysplastic syndrome in whom fluorescent in situ hybridization confirmed the non-random translocation but molecular biology analyses revealed a ETV6/GOT1 chimera varying from the first case described.

Abstract
Insulin-degrading enzyme (IDE) is a zinc metalloprotease that degrades the amyloid beta-peptide, the key component of Alzheimer disease (AD)-associated senile plaques. We have previously reported evidence for genetic linkage and association of AD on chromosome 10q23-24 in the region harboring the IDE gene. Here we have presented the first functional assessment of IDE in AD families showing the strongest evidence of the genetic linkage. We have examined the catalytic activity and expression of IDE in lymphoblast samples from 12 affected and unaffected members of three chromosome 10-linked AD pedigrees in the National Institute of Mental Health AD Genetics Initiative family sample. We have shown that the catalytic activity of cytosolic IDE to degrade insulin is reduced in affected versus unaffected subjects of these families. Further, we have shown the decrease in activity is not due to reduced IDE expression, suggesting the possible defects in IDE function in these AD families. In attempts to find potential mutations in the IDE gene in these families, we have found no coding region substitutions or alterations in splicing of the canonical exons and exon 15b of IDE. We have also found that total IDE mRNA levels are not significantly different in sporadic AD versus age-matched control brains. Collectively, our data suggest that the genetic linkage of AD in this set of chromosome 10-linked AD families may be the result of systemic defects in IDE activity in the absence of altered IDE expression, further supporting a role for IDE in AD pathogenesis.

Abstract
We present one case of a metachronous, atypical, multifocal renal oncocytoma with a concomitant chromophobe renal cell carcinoma (RCC) of the contralateral side and one case of bilateral and multifocal oncocytomas. Oncocytomas are benign renal tumours that rarely appear bilateral or multifocal or with coexisting RCC. A common pathogenic denominator of oncoytomas and RCC is being discussed. The first case was a 63 years old patient presenting with a history of nephrectomy for a pT1 G1 pN0 R0 papillary RCC 4 years prior to presentation, showed two tumours of a singular kidney. Upon nephron-sparing surgery one typical and one atypical oncocytoma with an invasion of the perinephric fat were found. Comparative genomic hybridisation was performed. Both tumours revealed genetic alterations with loss of genetic material on chromosome 1p. The second case was a 62 years old patient presenting with multifocal and bilateral renal tumours of undeclared dignity upon imaging. During open exploration all tumours could be removed by nephron-sparing surgery and were identified as oncocytomas. Again comparative genomic hybridisation was performed. All 4 tumours revealed genetic alterations with loss of genetic material on chromosome 1p, one of the tumours an additional loss of chromosome 10.

Abstract
The molecular basis of ovarian cancer development has not been fully elucidated. In this study, genetic alterations in ovarian cancer were identified by arbitrarily primed polymerase chain reaction (AP-PCR). A gene in DNA fingerprinting, amplified from primer AE11, was cloned, sequenced, and identified by comparison with known genes in the genome database. Gene amplification in chromosome 10q24.3 was identified and measured by real-time PCR. Three out of 20 cases harbored this gene amplification. This amplified region was identified as IVS-4 of the glutathione-S-transferase Omega 2 (GSTO2) gene. Therefore, the mutations in all 6 exons of the GSTO2 gene were determined. The A to G transition at codon 142 in exon 4 (AAT to GAT, N142D) was observed. The frequency of GSTO2 gene polymorphism was analyzed in 20 ovarian cancers, compared with 41 normal individuals. The gene frequencies of D142 and N142 allele in ovarian cancer cases were 0.3 and 0.7, whereas in normal females, they were 0.2 and 0.8, respectively. The odds ratio of D142 allele in ovarian cancer was 1.73 (95% CI = 0.51-5.89), indicating that this GSTO2 gene polymorphism may be associated with the risk of ovarian cancer.

Abstract
Current studies of facioscapulohumeral muscular dystrophy (FSHD) are confined to the white population. The authors surveyed 110 healthy individuals and 27 families with FSHD including 55 patients and 74 relatives by pulsed-field gel electrophoresis. The authors report the characteristics of translocation and genotype-phenotype correlation, and their results indicate 4q to 10q translocation contributes to the occurrence of de novo mutation. This leads to a more severe phenotype in the Chinese population comparing to EcoRI allele sizes and the intersexual difference.

Abstract
Imatinib mesylate has been reported to produce positive results in atypical chronic myeloproliferative disorders (CMD) with chromosomal translocations that disrupt the platelet-derived growth factor receptor beta gene (PDGFRB). We used imatinib to treat a 49-year old man with atypical CMD in accelerated phase and the H4 (D10S170)-PDGFRB fusion gene. After 3 months of treatment, we observed grade 4 hematologic toxicity and a lack of response.

Abstract
Late-onset familial Alzheimer disease (LOFAD) is a genetically heterogeneous and complex disease for which only one locus, APOE, has been definitively identified. Difficulties in identifying additional loci are likely to stem from inadequate linkage analysis methods. Nonparametric methods suffer from low power because of limited use of the data, and traditional parametric methods suffer from limitations in the complexity of the genetic model that can be feasibly used in analysis. Alternative methods that have recently been developed include Bayesian Markov chain-Monte Carlo methods. These methods allow multipoint linkage analysis under oligogenic trait models in pedigrees of arbitrary size; at the same time, they allow for inclusion of covariates in the analysis. We applied this approach to an analysis of LOFAD on five chromosomes with previous reports of linkage. We identified strong evidence of a second LOFAD gene on chromosome 19p13.2, which is distinct from APOE on 19q. We also obtained weak evidence of linkage to chromosome 10 at the same location as a previous report of linkage but found no evidence for linkage of LOFAD age-at-onset loci to chromosomes 9, 12, or 21.

Abstract
Chromosome 10p terminal deletions have been associated with a DiGeorge like phenotype. Haploinsufficiency of the region 10p14-pter, results in hypoparathyroidism, sensorineural deafness, renal anomaly, that is the triad that features the HDR syndrome. Van Esch (2000) identified in a HDR patient, within a 200 kb critical region, the GATA3 gene, a transcription factor involved in the embryonic development of the parathyroids, auditory system and kidneys. We describe a new male patient, 33-year-old, with 10p partial deletion affected by hypocalcemia, basal ganglia calcifications and a severe autistic syndrome associated with mental retardation. Neurologically he presented severe impairment of language, hypotonia, clumsiness and a postural dystonic attitude. A peripheral involvement of auditory pathways was documented by auditory evoked potentials alterations. CT scan documented basal ganglia calcifications. Hyperintensity of the lentiform nuclei was evident at the MRI examination. Renal ultrasound scan was normal. Haploinsufficiency for GATA3 gene was documented with FISH analysis using cosmid clone 1.2. Phenotypic spectrum observed in del (10p) is more severe than the classical DGS spectrum. GATA3 has been found to regulate the development of serotoninergic neurons. A serotoninergic dysfunction may be linked with autism in this patient.

Abstract
Recent data in yeast and Drosophila suggest a domain-like centromere structure with a modified chromatin core and flanking regions of heterochromatin. We have analyzed a functional human centromere and defined a region of increased chromosome scaffold/matrix attachment that overlaps three other distinct and nonoverlapping domains for constitutive centromere proteins CENP-A and CENP-H, and heterochromatin protein HP1. Transcriptional competency is intact throughout the S/MAR-enriched region and within the CENP-A- and CENP-H-associated chromatin. These results provide insights into the relationship between centromeric chromatin and transcriptional competency in vivo, highlighting the permissibility of transcription within the constitutively modified, nonheterochromatic chromatin of a functional eukaryotic centromere.

Abstract
The gene GAD2 encoding the glutamic acid decarboxylase enzyme (GAD65) is a positional candidate gene for obesity on Chromosome 10p11-12, a susceptibility locus for morbid obesity in four independent ethnic populations. GAD65 catalyzes the formation of gamma-aminobutyric acid (GABA), which interacts with neuropeptide Y in the paraventricular nucleus to contribute to stimulate food intake. A case-control study (575 morbidly obese and 646 control subjects) analyzing GAD2 variants identified both a protective haplotype, including the most frequent alleles of single nucleotide polymorphisms (SNPs) +61450 C>A and +83897 T>A (OR = 0.81, 95% CI [0.681-0.972], p = 0.0049) and an at-risk SNP (-243 A>G) for morbid obesity (OR = 1.3, 95% CI [1.053-1.585], p = 0.014). Furthermore, familial-based analyses confirmed the association with the obesity of SNP +61450 C>A and +83897 T>A haplotype (chi(2) = 7.637, p = 0.02). In the murine insulinoma cell line betaTC3, the G at-risk allele of SNP -243 A>G increased six times GAD2 promoter activity (p < 0.0001) and induced a 6-fold higher affinity for nuclear extracts. The -243 A>G SNP was associated with higher hunger scores (p = 0.007) and disinhibition scores (p = 0.028), as assessed by the Stunkard Three-Factor Eating Questionnaire. As GAD2 is highly expressed in pancreatic beta cells, we analyzed GAD65 antibody level as a marker of beta-cell activity and of insulin secretion. In the control group, -243 A>G, +61450 C>A, and +83897 T>A SNPs were associated with lower GAD65 autoantibody levels (p values of 0.003, 0.047, and 0.006, respectively). SNP +83897 T>A was associated with lower fasting insulin and insulin secretion, as assessed by the HOMA-B% homeostasis model of beta-cell function (p = 0.009 and 0.01, respectively). These data support the hypothesis of the orexigenic effect of GABA in humans and of a contribution of genes involved in GABA metabolism in the modulation of food intake and in the development of morbid obesity.

Abstract
The nucleoporin 98 gene (NUP98) has been reported to be fused to 13 partner genes in hematological malignancies with 11p15 translocations. Twelve of them have been identified in patients with myeloid neoplasias and only 1, RAP1GDS1 (4q21), is fused with NUP98 in five patients with T-cell acute lymphoblastic leukemia (T-ALL). Three of these patients coexpressed T and myeloid markers, suggesting the specific association of t(4;11)(q21;p15) with a subset of T-ALL originating from an early progenitor, which has the potential to express mature T-cell antigens as well as myeloid markers. We describe here a new NUP98 partner involved in a t(10;11)(q25;p15) in a patient with acute biphenotypic leukemia, showing coexpression of mature T and myeloid markers. The gene involved, located in 10q25, was identified as ADD3 using 3'-RACE. ADD3 codes for the ubiquitous expressed subunit gamma of the adducin protein, and it seems to play an important role in the skeletal organization of the cell membrane. Both NUP98-ADD3 and ADD3-NUP98 fusion transcripts are expressed in the patient. This is the second partner of NUP98 described in T-ALL. Adducin shares with the product of RAP1GDS1, and with all of the nonhomeobox NUP98 partners, the presence of a region with significant probability of adopting a coiled-coil conformation. This region is always retained in the fusion transcript with the NH(2) terminus FG repeats of NUP98, suggesting an important role in the mechanism of leukemogenesis.

Abstract
Fluorescence in situ hybridization (FISH) analysis in a case of infant acute monocytic leukemia M5 revealed a complex rearrangement between chromosomes 10 and 11, leading to the disruption of the MLL gene. Using two painting probes for chromosomes 10 and 11 and a specific probe for the MLL gene localized on 11q23, we observed a paracentric inversion of the 11q13-q23 fragment translocated to 10p12. Molecular analysis showed that AF10 localized on 10p12 was the fusion partner gene of MLL in this rearrangement (10;11). This report underlined the usefulness of FISH and molecular techniques in identifying complex rearrangements.

Abstract
BACKGROUND AND OBJECTIVES Myelodysplastic syndrome (MDS), secondary acute myeloid leukemia (sAML) and clonal karyotypic abnormalities, have been recognized as relatively frequent and potentially serious complications of autologous peripheral blood progenitor cell transplantation (PBPCT) for Hodgkin's disease (HD), non-Hodgkin's lymphoma (NHL) or multiple myeloma (MM). DESIGN AND METHODS We analyzed 66 patients, undergoing PBPCT for HD, NHL, MM or chronic lymphocytic leukemia (CLL). Patients reported in this study had to be in continuous complete remission after transplantation without receiving chemo-radiotherapy or other biological response modifiers, had to show absence of cytogenetic abnormalities and myelodysplastic features at transplantation and had to have at least 12 months of follow-up. We evaluated the bone marrow, peripheral blood, cytogenetics and clonality (HUMARA) 12 months after the transplant and thereafter every 12 months or every 6 months if lineage dysplasia, clonal or cytogenetic abnormalities were detected. RESULTS We did not observe MDS/sAML, according to the FAB classification, in 163 assessments of 66 patients over a median follow-up of 25 months (range 12-106) after PBPCT. Twelve patients showed lineage dysplasia: six patients had dyserythropoiesis, 2 patients dysgranulopoiesis, one dysmegakaryocytopoiesis, two patients showed double lineage dysplasia (erythroid and granulocytic), and one patient showed dysgranulopoiesis at the first control acquiring dyserythropoiesis at the next follow-up. We found three cytogenetic abnormalities in the absence of concomitant dysplastic features: transient -5q, -Y, fra(10)(q25). The female patient with the cytogenetic abnormality -5q showed transient unbalanced clonality by HUMARA assay; further controls documented normalization of both clonality and cytogenetics. INTERPRETATION AND CONCLUSIONS The occurrence of MDS/sAML depends on a variety of risk factors such as the number and type of prior courses of chemo-radiotherapy, total body irradiation in conditioning regimen, cytogenetic and morphologic alterations prior to transplant. This may account for the difference in reporting MDS/sAML after transplantation. The lack of exposure to recognized risk factors for MDS/sAML in our patients may account for the absence of this complication in this study. We consider that the use of stringent morphologic criteria, especially during the first period after PBPCT, combined with cytogenetic, clonality and FISH analyses are necessary for a correct diagnosis of MDS and to overcome the limitations of the FAB and WHO classifications in this setting.

Abstract
Familial papillary thyroid carcinoma (PTC) is a well recognized disease. However, genetic predisposition to familial PTC is rare and the molecular alterations at the origin of the pathology are unknown. The association between PTC and lymphocytic thyroiditis (LT) has been reported recently. We communicate here 6 cases of PTC associated with LT in 2 unrelated families. PTC was diagnosed on classical nuclear and architectural criteria. It was bilateral in 5 cases. Architecture was equally distributed between typical PTC and its follicular variant. LT was present in variable degrees, including in 4 cases, oncocytic metaplasia. Using the RT-PCR technique, we observed a RET/PTC rearrangement in the carcinomatous areas of patients of both families: PTC1 in family 1 and PTC3 in family 2 and a RET/PTC rearrangement in non-malignant thyroid tissue with LT in family 2. The RET/PTC band was weaker or absent in pure LT areas. Furthermore, using a polyclonal ret antibody, an apical or a diffuse cytoplasmic ret onc protein immunolabelling was observed in the three patients with RET/PTC1 rearrangement and in the three patients with RET/PTC3 rearrangement. In conclusion our data: (1) show the presence of a RET/PTC 1 or 3 rearrangement (depending on the family) together with a variable expression of ret protein in all the PTCs; (2) suggest that the molecular event at the origin of the PTCs seems to be particular to each one of the studied families; and (3) confirm that the ret proto-oncogene activating rearrangement(s) is an early event in the thyroid tumorigenic process and that it can be observed in association with LT.

Abstract
The t(10;11)(p13;q14-21) is a non-random translocation described in acute lymphoblastic and myeloid leukaemias. It results in the fusion of the gene CALM, which encodes a clathrin assembly protein, on 11q14 to the gene AF10, a putative transcription factor on 10p13. Here we describe for the first time, the occurrence of a CALM-AF10 fusion in a case of acute megakaryoblastic leukaemia. Fluorescence in situ hybridisation and reverse transcriptase polymerase chain reaction were used to confirm the presence of a CALM-AF10 fusion. A novel splice variant of CALM missing nt 1927-2091 was also detected. Though CALM is a cytoplasmic protein, the chimaeric fusion product is able to localise to both the nucleus and cytoplasm. Analysis of the fusion variants suggests, however, that the critical fusion product is likely to be cytoplasmic and contain the interactive leucine zipper of AF10.

Abstract
Glioblastoma multiforme is the most malignant astrocytic glioma and usually resistant to chemotherapy. A small fraction of glioblastomas may contain areas with histological features of oligodendroglial differentiation. To determine the molecular genetic alterations in such "glioblastomas with oligodendroglial component", we investigated 13 of these tumors for genetic alterations and/or expression of the TP53, CDKN2A, PTEN, and EGFR genes. In addition, we performed microsatellite analyses for loss of heterozygosity (LOH) on chromosome arms 1p, 19q and 10q. None of tumors showed evidence for LOH on 10q. LOH on 1p was detected in 3 tumors, 1 of which additionally showed LOH on 19q. The 3 tumors with LOH on 1p showed neither TP53 mutations nor nuclear p53 accumulation. In contrast, 9 of 10 tumors without demonstrated losses on 1p showed nuclear p53 accumulation. TP53 mutations were identified in 3 of these cases. Further aberrations detected were epidermal growth factor receptor (EGFR) overexpression (3 of 13 tumors), homozygous CDKN2A deletion (2 of 11 tumors), and PTEN mutation (1 of 13 tumors). Taken together, our results indicate that "glioblastomas with oligodendroglial component" carry heterogeneous genetic alterations. LOH on 10q, PTEN mutation, and homozygous CDKN2A deletion appear to be less common in these tumors as compared to ordinary glioblastomas. Furthermore, a subset of these tumors demonstrates LOH on 1p, i.e., an alteration that has recently been linked to chemosensitivity and good prognosis in anaplastic oligodendrogliomas.

Abstract
We report two patients with trisomy 21 whose karyotypes revealed unusual translocations. In the first case there was a tandem translocation with two chromosomes 21 attached to the long arm of chromosome 10 (45,XX + tan(10:21;21). In the second case there was an inverted tandem translocation between two chromosomes 21 attached through their long arms (46,XY + dic(21q:21q). The clinical picture in both patients was not different from the usually found in trisomy 21. Since the parent's karyotypes were normal in both cases, it is assumed that both translocations arose "de novo". The need for karyotyping all cases of Down syndrome is emphasized.

Abstract
The RET proto-oncogene is often activated through somatic rearrangements in papillary thyroid carcinomas (PTCs). Three main rearranged forms of RET have been described: RET/PTC1 and RET/PTC3, which arise from a paracentric inversion and RET/PTC2, which originates from a 10 : 17 translocation. We previously developed a dual-color FISH test to detect these RET rearrangements in interphase nuclei of thyroid lesions. This approach allowed us to detect a novel translocation involving the RET region, which was not detectable by RT - PCR with specific primers for known rearrangements. A combination of RT - PCR and RACE analyses finally led to the identification of the fusion gene, which involves the 5' portion of PCM-1, a gene coding for a centrosomal protein with distinct cell cycle distribution, and the RET tyrosine kinase (TK) domain. FISH analysis confirmed the chromosomal localization of PCM-1 on chromosome 8p21-22, a region commonly deleted in several tumors. Immunohistochemistry, using an antibody specific for the C-terminal portion of PCM-1 showed that the protein level is drastically decreased and its subcellular localization is altered in thyroid tumor tissue with respect to normal thyroid. However, heterozygosity is retained for seven microsatellite markers in the 8p21-22 region, suggesting that the non-rearranged PCM-1 allele is not lost and that the translocation is balanced.

Abstract
Alteration of chromosome 10 is common in human melanomas and usually entails the loss of an entire chromosome homologue. Although the reasons for monosomy in cancer has remained obscure, one possibility is that multiple tumor suppressor genes residing on this chromosome must be lost in unison during tumor progression, and this is easier to accomplish by chromosome segregation rather than by multiple mutational and/or deletion events. The localization and identification of these genes has been hampered by the monosomy itself, which has resulted in a paucity of small defining deletions in tumors. Here, we have addressed the issue of monosomy in tumor development by using functional complementation mapping to localize and demonstrate the existence of different melanoma suppressor genes on chromosome 10 and assigned each locus a distinct tumorigenic phenotype. We report that a locus on 10q distal to 10q23.1, likely involving the PTEN tumor suppressor, causes a severe reduction in the kinetics of melanoma tumor formation in animals. In contrast, a previously unrecognized region at 10p15.3 has a distinct, but lesser, effect on in vivo melanoma growth. Thus, the loss of both of these regions, which is accomplished by tumor-associated monosomy, provides a significant growth advantage over the individual loss of either region, thereby explaining the monosomy observed in sporadic melanomas.

Abstract
Recurrent translocation t(10;11) has been reported to be associated with acute myeloid leukemia (AML). Recently, two types of chimeric transcripts, MLL-AF10 in t(10;11)(p12;q23) and CALM-AF10 in t(10;11)(p13;q14), were isolated. t(10;11) is strongly associated with complex translocations, including invins(10;11) and inv(11)t(10;11), because the direction of transcription of AF10 is telomere to centromere. We analyzed a patient of AML with t(10;11)(p11.2;q23) and identified ABI-1 on chromosome 10p11.2, a human homolog to mouse Abl-interactor 1 (Abi-1), fused with MLL. Whereas the ABI-1 gene bears no homology with the partner genes of MLL previously described, the ABI-1 protein exhibits sequence similarity to protein of homeotic genes, contains several polyproline stretches, and includes a src homology 3 (SH3) domain at the C-terminus that is required for binding to Abl proteins in mouse Abi-1 protein. Recently, e3B1, an eps8 SH3 binding protein 1, was also isolated as a human homolog to mouse Abi-1. Three types of transcripts of ABI-1 gene were expressed in normal peripheral blood. Although e3B1 was considered to be a full-length ABI-1, the MLL-ABI-1 fusion transcript in this patient was formed by an alternatively spliced ABI-1. Others have shown that mouse Abi-1 suppresses v-ABL transforming activity and that e3B1, full-length ABI-1, regulates cell growth. In-frame MLL-ABI-1 fusion transcripts combine the MLL AT-hook motifs and DNA methyltransferase homology region with the homeodomain homologous region, polyproline stretches, and SH3 domain of alternatively spliced transcript of ABI-1. Our results suggest that the ABI-1 gene plays a role in leukemogenesis by translocating to MLL.

Abstract
Rabbit epithelial basolateral chloride conductance regulator (EBCR) and rat canalicular multispecific organic anion transporter (Cmoat) are found to be homologues based on protein sequence comparison and Northern blot analysis. EBCRis, therefore, renamed as rabbit Cmoat. The gene encoding CMOAT, a transporter possibly involved in Dubin-Johnson syndrome in humans, is mapped on human chromosome 10q24 and mouse chromosome 19D2.

Abstract
A t(X;10)(q22;q23.2) translocation was detected as the only chromosomal aberration in primary short-term cultured cells from an angiomyoma of a 58-year-old woman; 6p, 13q, and 21q rearrangements have been previously demonstrated by others in two cases of angiomyoma. This type of translocation has not been reported in other benign tumors including leiomyomas and angiomyomas, although it has been detected in an ependymoma. This is thought to be a third case of angiomyoma showing karyotypic abnormalities.

Abstract
Utilizing tissue microdissection and PCR techniques, we have examined 35 prostate tumors paired with normal tissues from the same patients for allelic loss at 24 polymorphic loci spanning chromosome 10. Twenty-five tumors (71%) were deleted for at least one chromosome 10 locus. Of the total 35 tumors, 6 (17%) were deleted for 10p loci only, 5 (14%) for 10q loci only, and 14 (40%) were deleted for both 10p and 10q loci. The common region of deletion on 10p included loci D10S211-D10S89-D10S111. Fluorescence in situ hybridization of yeast artificial chromosome probes encompassing these loci demonstrated that the 10p region of deletion maps to 10p11.2. Losses involving 10p loci alone were most common in localized (5/14, 36%) and least common in metastatic (0/8) tumors. The common region of deletion on 10q included loci D10S219-D10S215, consistent with the major region of deletion recently defined for prostate tumors on 10q. Losses involving 10q loci alone were lowest in localized and locally invasive tumors (1/14 and 2/12, respectively) and highest in tumors metastatic to regional lymph nodes (2/8). These results suggest that 10p losses may define less invasive tumors, whereas 10q losses may play a role in the progression to more advanced tumor states in the prostate. Furthermore, this is the first report of allelic loss of a defined region on 10p potentially harboring tumor suppressor gene loci in human prostate cancer.

Abstract
The human prosaposin gene (PSAP) was previously localized to 10q21-->q22 by isotopic in situ hybridization using a human prosaposin cDNA as a probe. The present study, using fluorescence in situ hybridization with a mouse genomic prosaposin fragment as probe, confirms the localization of PSAP and precisely maps it to band 10q22.1.

Abstract
The sequence-tagged site (STS) D10S170, also referred to as H4, is a gene of unknown function. Its 5' end was found fused to the catalytic domain of the RET protooncogene to generate RET/PTC 1, the most common form of PTC oncogenes in human papillary thyroid carcinoma. This gene has previously been assigned to a very large genomic region, 10q11.22-->q22.1. Here, we describe the application of a novel hybridization scheme to the physical and genetic mapping of D10S170. First, we selected a homologous large-insert DNA clone from a human P1 library by filter hybridization and confirmed its authenticity by Southern blot analysis. Triple-color fluorescence in situ hybridization (FISH) experiments mapped this clone to l0q21.2-->q21.3. "Binning" experiments were performed using a quadruple-color FISH approach aimed toward placing the gene in a genetic interval defined by differentially labeled P1 DNA probes containing known polymorphic markers. We found that multicolor FISH greatly expedites chromosomal mapping. Finally, we applied our FISH approach to determine the extent of deletion involving this locus (D10S170) in a papillary thyroid cancer cell line, TPC-1.

Abstract
The gene on chromosome 10 at band p12 (AF10), involved in the t(10;11) translocation in acute myeloid leukemia, has been identified and shown to contain conserved zinc finger and leucine zipper domains. These regions are highly homologous to the equivalent regions on AF17, the gene involved in the t(11;17) translocations. A series of adult, childhood, and infant leukemias with either simple or complex versions of the t(10;11) has been examined by Southern analysis and shown to involve rearrangement to the HRX locus. Reverse transcriptase-polymerase chain reaction from either bone marrow or peripheral blood cells showed that HRX sequence was fused to AF10 sequence in all 8 cases and subsequent sequence analysis showed an in-frame fusion between the HRX and AF10 sequence. A consistent feature of these fusions was the juxtaposition of the leucine dimerization motif of AF10 onto the NH2-terminal region of HRX. The published data suggest that a similar conclusion can be drawn about the t(11;17) translocation, implying a critical role for this motif in the chimaeric HRX protein.

Abstract
The NFKB2(lyt-10) gene codes for a protein that is a member of the NK-kappa B/rel family of transcription factors containing a DNA-binding rel domain and a carboxy-terminal ankyrin-like domain. The NFKB2 gene represents a candidate proto-oncogene, since it has been found to be involved in a chromosomal translocation t(10;14)(q24;q32) in one case of B-cell lymphoma and in gene rearrangements in various types of lymphoid malignancies. To elucidate the structural and functional consequences of NFKB2 rearrangements, we report the molecular characterization of three novel rearranged NFKB2 genes in lymphoid tumors. In one case of multiple myeloma (MM), cloning and sequencing analysis of reciprocal breakpoint sites showed that they occurred within intron 15 of the NFKB2 gene and led to the complete deletion of the 3' portion of the gene coding for the ankyrin domain. Fluorescent in situ hybridization (FISH) analysis showed that the novel regions involved in the NFKB2 rearrangement originated from chromosome 7q34, thus implying the occurrence of a t(7;10)(q34;q24) reciprocal chromosomal translocation. In one case of T-cell cutaneous lymphoma (CTCL) and in one of B-cell chronic lymphocytic leukemia (B-CLL), NFKB2 rearrangements occurred, respectively, within exons 18 and 20 of the gene and involved recombinations with distinct regions of chromosome 10q24. Molecular analysis suggested that these rearrangements may occur as a consequence of small internal chromosomal deletions. In both of these cases, the rearrangements led to specific carboxy-terminal truncations of NFKB2 generating abnormal transcripts that coded for proteins lacking portions of the ankyrin domain. These proteins localize in the nucleus, suggesting their constitutive activation in vivo. Overall, our results indicate that NFKB2 rearrangements in lymphoid neoplasia may occur by heterogeneous mechanisms, including internal chromosomal deletion or chromosomal translocation. The common consequence of these rearrangements appears to be the deletion of 3' sequences of NFKB2 leading to the production of carboxy-truncated constitutively nuclear proteins that may be involved in tumorigenesis.

Abstract
We describe a patient with severe failure to thrive, mild-moderate developmental delay, cleft lip and palate, and other anomalies. Routine cytogenetic analysis documented a de novo chromosome rearrangement involving chromosome 4, but the origin of the derived material was unknown. Using chromosome specific painting probes, the karyotype was defined as 46,XY,der(4) t(4;10)(q35;p11.23). Characterization of the dup(10p) by fluorescence in situ hybridization (FISH) analysis provides another example of the usefulness of this technology in identifying small deletions, duplications, or supernumerary marker chromosomes.

Abstract
Partial duplication of 10q is a recognizable clinical entity. In most of the reported cases, the trisomic segment is identified by a balanced translocation state in a parent. Verification remains a problem in de novo cases. However, the recent availability of whole chromosome probes allows for confirmatory diagnosis of suspected cases. We describe a case of de novo duplication (10q) with verification using DNA in situ hybridization.

Abstract
Activation of the RET protooncogene tyrosine kinase (tk) by fusion with other genes is a frequent finding in papillary thyroid carcinoma. The tk domain of proto-RET can be fused either with the D10S170 gene generating the RET/PTC1 transforming sequence or with sequences belonging to the gene encoding the regulatory subunit RIA of c-AMP-dependent protein kinase A, thus forming the RET/PTC2 oncogene. We have previously shown that an inversion of chromosome 10, inv(10)(q11.2q21), is responsible for the generation of the RET/PTC1. Here we report that a chromosomal translocation, t(10;17)(q11.2;q23), juxta-poses the tk domain of the RET protooncogene, which resides on chromosome 10, to a 5' portion of the RIA gene on chromosome 17, leading to the formation of the chimeric transforming gene RET/PTC2. The finding of the transforming protein in primary tumor cell extracts supports the conclusion that RET/PTC2 activation plays a role in papillary thyroid tumorigenesis.

Abstract
Cancers in which mutations have been identified in putative tumor suppressor genes, such as the TP53 gene, the retinoblastoma (RBI) gene, the adenomatous polyposis coli (APC) gene, and the Wilms tumor (WTI) gene, frequently show loss of the corresponding allele on the homologous chromosome. To identify locations of tumor suppressor genes involved in uterine cancer, we examined loss of heterozygosity (LOH) by using genomic probes detecting RFLPs in 35 uterine cancers at 29 loci throughout the genome, and with highly informative microsatellite markers in 21 uterine cancers at nine putative or known tumor suppressor gene loci. High frequencies of allelic loss found at loci on 3p (71%), 9q (38%), 10q (35%), and 17p (35%) suggest that tumor suppressor genes involved in uterine carcinogenesis exist in these regions. There were no significant differences in frequencies of LOH between cancers of the uterine cervix and cancers of the uterine endometrium at any of the loci tested.

Abstract
We report a familial recombination of a pericentric inversion of chromosome 10 resulting in 2 affected relatives who had 10p trisomy and 10q monosomy with the karyotypic abnormality designated rec(10) dup p,inv(10) (p11.2q26). Both of these individuals had the typical characteristics of 10p trisomy, however, at birth the proposita had mild facial anomalies suggesting that the distinct facial characteristics may be of postnatal onset in some cases. In addition, the proposita had gastroesophageal reflux causing severe anemia. The phenotype of our patients is compared to 41 patients with 10p trisomy reported in the literature.

Abstract
Glutamate dehydrogenase (GLUD) is an important mitochondrial enzyme that participates in neuronal transmission by catalyzing the deamination of L-glutamate, which serves as a potent excitatory neurotransmitter. The direct involvement of GLUD in the pathogenesis of certain human neurodegenerative disorders has been suggested recently. To investigate its possible role in the induction and progression of these disorders, we have initiated studies focusing on the chromosomal organization of the several members of the GLUD family and their functional status. In the present study using a panel of human x rodent somatic cell hybrids and in situ hybridization to metaphase chromosomes, we documented that the members of the GLUD gene family are dispersed in the human genome. The functional GLUD1 gene was mapped to chromosome 10q22.3-q23, and an intronless processed gene (GLUDP1) to chromosome Xq22-q23, while the truncated intron-containing GLUD pseudogene GLUDP2 was also assigned on chromosome 10, but not closely linked to the GLUD1 gene. These results provide novel information concerning the chromosomal organization of the human GLUD gene family.

Abstract
The issue of telomeric sequences on deleted chromosomes and double minutes (dmin) was investigated by examining the cell line HL-60 with fluorescence in situ hybridization using a human plasmid DNA sequence with 800 bp TTAGGG repeats. This cell line showed telomeric sequences on the deleted short arms of chromosomes 9 and 10, with the results suggesting that so-called terminal deletion may be, in fact, an interstitial deletion, or that telomeric sequences may be synthesized by telomerase after deletion. On the other hand, numerous dmin showed no evidence of hybridization with the telomeric probe. This suggests that the characteristics unequal distribution of dmin during mitosis may result from the lack of not only centromeres but also telomeres.

Abstract
A fluorescence in situ hybridization (FISH) physical map of 14 polymorphic loci on chromosome 10 covers over 62% of the fractional length of chromosome 10. The positions of three previously mapped loci are confirmed, nine more are refined, and two new loci are cytogenetically mapped. The order of loci determined by FISH agrees with that obtained by genetic linkage studies. When the distance estimates for the physical map are compared to the distance estimates of our existing linkage map, the sex average ratio of the fractional length (FL) per centimorgan (cM) for this portion of chromosome 10 is 0.004 (or 0.4% FL/cM). However, the average ratios for male- and female-specific genetic distances are quite different, in agreement with an overall higher rate of recombination in females (0.008 FL/cM and 0.003 FL/cM, respectively). Moreover, the ratio across the centromere is larger for both the male (0.031 FL/cM) and the female (0.009 FL/cM) than the ratio encompassing the q arm (0.006 FL/cM for males and 0.002 FL/cM for females), suggesting that there is reduced recombination at the centromere in both the male and the female maps when compared to the physical distance generated from FISH on metaphase chromosomes.

Abstract
Two related zinc finger (ZNF) gene clusters from the pericentromeric region of human chromosome 10, defined by cDNAs of the KOX series, have been cloned in yeast artificial chromosomes (YACs). The two clusters evolved by duplication of an ancestral gene cluster before the divergence of the human and great ape lineages. Included in cluster A are the ZNF gene sequences ZNF11A, ZNF33A, and ZNF37A, while cluster B comprises the related sequences ZNF11B, ZNF33B and ZNF37B. Genes from both clusters are expressed: cDNAs KOX2, KOX31 and KOX21 derive from ZNF11B, ZNF33A and ZNF37A, respectively. Further YACs have been isolated which link ZNF11A and ZNF33A to another gene, ZNF25, defined by cDNA clone KOX19. Therefore ZNF25 also forms part of cluster A, but has no counterpart in cluster B. Surprisingly, the KOX ZNF gene clusters are located on opposite sides of the centromere: cluster A maps to 10p11.2, while cluster B is in 10q11.2. This suggests the occurrence during primate evolution of a previously undescribed pericentric inversion subsequent to the cluster duplication. The evolution of this subset of KOX ZNF genes has therefore involved three types of genetic event: local gene duplication, gene cluster duplication, and chromosome rearrangement.

Abstract
The gene responsible for multiple endocrine neoplasia type 2A (MEN 2A) has been localized to the pericentromeric region of chromosome 10. Several markers that fail to recombine with MEN2A have been identified, including D10Z1, D10S94, D10S97, and D10S102. Meiotic mapping in the MEN2A region is limited by the paucity of critical crossovers identified and by the dramatically reduced rates of recombination in males. Additional approaches to mapping loci in the pericentromeric region of chromosome 10 are required. We have undertaken the generation of a detailed physical map by radiation hybrid mapping. Here we report the development of a radiation hybrid panel and its use in the mapping of new DNA markers in pericentromeric chromosome 10. The radiation-reduced hybrids used for mapping studies all retain small subchromosomal fragments that include both D10S94 and D10Z1. One hybrid was selected as the source of DNA for cloning. One hundred five human recombinant clones were isolated from a lambda library made with pp11A DNA. We have completed regional mapping of 22 of those clones using our radiation hybrid mapping panel. Seven markers have been identified and, when taken together with previously meiotically mapped markers, define eight radiation hybrid map intervals between D10S34 and RBP3. The identical order is found for a number of these using either the radiation hybrid mapping panel or the meiotic mapping panel. We believe that this combination cloning and mapping approach will facilitate the precise positioning of new markers in pericentromeric chromosome 10 and will help in refining further the localization of MEN2A.

Abstract
Three members of the human zinc finger Krüppel family, ZNF11/KOX2, ZNF22/KOX15, and ZNF25/KOX19, have been regionally localized to the pericentromeric region of chromosome 10 by in situ chromosomal hybridization and somatic cell hybrid analysis. ZNF25/KOX19 is located centromeric to a breakpoint in chromosome band 10q11.2 in the chromosome region 10p11.2-q11.2, whereas ZNF22/KOX15 maps distal to it in band 10q11.2. Sequences hybridizing to the KOX2 probe are found at two loci, ZNF11A and ZNF11B, that map proximal and distal to the 10q11.2 breakpoint, respectively. The two ZNF11 loci probably represent two related sequences in 10p11.2-q11.2. This cluster of ZNF/KOX genes is of particular interest since the loci for multiple endocrine neoplasia type 2A and 2B (MEN2A and MEN2B) syndromes have been assigned to this region by linkage analysis.

Abstract
Familial multiple endocrine neoplasia type 2A (MEN 2A) is a dominantly inherited cancer syndrome characterized by tumors in tissues derived from the neural crest. The disease manifests as medullary carcinoma of the thyroid, pheochromocytoma, and hyperparathyroidism. The MEN2A locus has been mapped near the centromere of chromosome 10 by linkage analysis. Statistical analyses have not resolved the location of MEN2A among several close markers. We have used our family material to refine the positions of 36 identified and confirmed crossovers among the markers most closely linked to MEN2A. This high-resolution meiotic mapping panel will help order loci in this pericentromeric region and narrow the region in which MEN2A maps.

Abstract
Cytogenetic and RFLP studies have shown that chromosome 10 is frequently lost in tumor cells from glioblastomas, suggesting that a suppressor gene important in tumorigenesis is present on this chromosome. Forty-one tumors were examined for loss of heterozygosity at 23 loci on chromosome 10 to determine the smallest common deletion interval on this chromosome. Seven tumors did not lose heterozygosity for any of the markers. Twenty-three tumors lost an allele for all the informative loci. In 11 tumors heterozygosity was maintained at some loci and lost at other loci, indicating partial deletion of chromosome 10. The common region of deletion in these 11 tumors was located in 10q24-q26 between the markers pHUK-8 and pMCT122.2.

Abstract
Cytogenetic analysis after short-term culture in vitro of primary tumor samples was attempted in 82 patients with prostatic cancer. Tumor material was obtained by radical prostatectomy or transurethral resection. Successful cytogenetic studies were performed on 57 tumors of which five were well, 30 moderately, and 22 poorly differentiated adenocarcinomas. Only normal karyotypes were found in 24 tumors. Structural nonclonal aberrations were detected in 18 and clonal karyotypic abnormalities in 15 tumors. The most common clonal numerical aberration was loss of the Y chromosome; a missing Y was found in six tumors, in three of these as the sole anomaly. Clonal structural chromosomal rearrangements, usually accompanied by numerical changes, were detected in 12 tumors. The rearrangements involved 18 of the 22 autosomes and the X chromosome. Chromosomes 1, 7, and 10 were most frequently affected. Deletions, duplications, inversions, insertions, and balanced as well as unbalanced translocations were represented. The breakpoints in chromosome 1 were scattered along both the short and long arms with no obvious clustering, whereas those in chromosomes 7 and 10 were clustered at bands 7q22 (two deletions and two duplications in four different tumors) and 10q24 (two translocations, one deletion, and one inversion in four tumors). One additional tumor displayed a derivative chromosome 10 with a breakpoint in 10q23, and one had monosomy 10. Altogether, these abnormalities resulted in loss of 10q24----qter in five tumors. Monosomy 8 and rearrangements of the short arm of chromosome 8 leading to loss of 8p21----pter were seen in four tumors. Double minute chromosomes were found in two tumors.

Abstract
By means of G-banding techniques, chromosome aberrations were studied in short-term cultures of normal renal parenchymal cells from 45 patients with renal cell carcinoma. Clonal chromosomal aberrations were detected in 29 patients; loss of the Y chromosome as well as trisomy X, 5, 7, 9, 10, 12, and 18 was found. Chromosomes 7 and 10 were involved preferentially. Results of fluorescence in situ hybridization with chromosome 7- and 10-specific DNA probes on non-cultured normal kidney cells suggested that the aberrations developed in vivo.
