Superimposed histologic and genetic mapping of chromosome 9 in progression of human urinary bladder neoplasia: implications for a genetic model of multistep urothelial carcinogenesis and early detection of urinary bladder cancer. (1/1486)

The evolution of alterations on chromosome 9, including the putative tumor suppressor genes mapped to the 9p21-22 region (the MTS genes), was studied in relation to the progression of human urinary bladder neoplasia by using whole organ superimposed histologic and genetic mapping in cystectomy specimens and was verified in urinary bladder tumors of various pathogenetic subsets with longterm follow-up. The applicability of chromosome 9 allelic losses as non-invasive markers of urothelial neoplasia was tested on voided urine and/or bladder washings of patients with urinary bladder cancer. Although sequential multiple hits in the MTS locus were documented in the development of intraurothelial precursor lesions, the MTS genes do not seem to represent a major target for p21-23 deletions in bladder cancer. Two additional tumor suppressor genes involved in bladder neoplasia located distally and proximally to the MTS locus within p22-23 and p11-13 regions respectively were identified. Several distinct putative tumor suppressor gene loci within the q12-13, q21-22, and q34 regions were identified on the q arm. In particular, the pericentromeric q12-13 area may contain the critical tumor suppressor gene or genes for the development of early urothelial neoplasia. Allelic losses of chromosome 9 were associated with expansion of the abnormal urothelial clone which frequently involved large areas of urinary bladder mucosa. These losses could be found in a high proportion of urothelial tumors and in voided urine or bladder washing samples of nearly all patients with urinary bladder carcinoma.  (+info)

Partial monosomy and partial trisomy 18 in two offspring of carrier of pericentric inversion of chromosome 18. (2/1486)

A pericentric inversion of chromosome 18 is described in the mother of a patient with clinical diagnosis of 18q--syndrome. The propositus' chromosome complement includes the recombinant 18 with deficiency of the distal one-third of the long arm and duplication of the terminal segment of the short arm. The propositus' sister carrier the recombinant 18 with a duplication of the distal one-third of the long arm and a deficiency of the terminal segment of the short arm. The relative length of the inverted segment represents about 60% of the total chromosome 18 length. The probability of recombinant formation following the occurrence of a chiasma within the inverted segment is predicted to be high.  (+info)

Origin of DNA damage in ejaculated human spermatozoa. (3/1486)

The molecular basis of many forms of male infertility is poorly defined. One area of research that has been studied intensely is the integrity of the DNA in the nucleus of mature ejaculated spermatozoa. It has been shown that, in men with abnormal sperm parameters, the DNA is more likely to possess strand breaks. However, how and why this DNA damage originates in certain males and how it may influence the genetic project of a mature spermatozoon is unknown. Two theories have been proposed to describe the origin of this DNA damage in mature spermatozoa. The first arises from studies performed in animal models and is linked to the unique manner in which mammalian sperm chromatin is packaged, while the second attributes the nuclear DNA damage in mature spermatozoa to apoptosis. One of the factors implicated in sperm apoptosis is the cell surface protein, Fas. In this review, we discuss the possible origins of DNA damage in ejaculated human spermatozoa, how these spermatozoa arrive in the ejaculate of some men, and what consequences they may have if they succeed in their genetic project.  (+info)

Isolation and characterization of a new human breast cancer cell line, KPL-4, expressing the Erb B family receptors and interleukin-6. (4/1486)

A new human breast cancer cell line, KPL-4, was recently isolated from the malignant pleural effusion of a breast cancer patient with an inflammatory skin metastasis. This cell line can be cultured under serum-free conditions and is tumorigenic in female athymic nude mice. Flow cytometric analysis revealed the expression of Erb B-1, -2 and -3. Dot blot hybridization showed a 15-fold amplification of the erb B-2. Reverse transcription-polymerase chain reaction analysis showed a detectable level of mRNA expression of all the Erb B family receptors. In addition, all the receptors were autophosphorylated under a serum-supplemented condition. Unexpectedly, transplanted KPL-4 tumours induced cachexia of recipient mice. A high concentration of interleukin-6 (IL-6) was detected in both the culture medium and the serum of mice. The weight of tumours significantly correlated with the serum IL-6 level. The antiproliferative effect of a humanized anti-Erb B-2 monoclonal antibody, rhuMAbHER2, was investigated. This antibody significantly inhibited the growth of KPL-4 cells in vitro but modestly in vivo. Loss of mouse body weight was partly reversed by rhuMAbHER2. These findings suggest that KPL-4 cells may be useful in the development of new strategies against breast cancer overexpressing the Erb B family receptors and against IL-6-induced cachexia.  (+info)

Subfertile men with constitutive chromosome abnormalities do not necessarily refrain from intracytoplasmic sperm injection treatment: a follow-up study on 75 Dutch patients. (5/1486)

A follow-up study was performed to investigate the impact of the detection of a chromosome abnormality in infertile men who are candidates for intracytoplasmic sperm injection (ICSI) treatment. In this collaborative study between clinical genetics centres and fertility clinics in the Netherlands, 75 ICSI couples of which the male partners had a chromosome abnormality were included. All couples were extensively counselled on the risk of having a chromosomally unbalanced child. Forty-two out of 75 couples chose to proceed with the ICSI treatment. So far, treatment has resulted in a pregnancy in 11 cases. Four of them opted to have invasive prenatal diagnosis. Despite the genetic risks related to a chromosome abnormality in infertile men, a small majority (56%) of the couples did not refrain from the ICSI treatment.  (+info)

Renal function studies in an infant with 4p (-) syndrome. (6/1486)

An infant with the syndrome of deletion of the short arm of chromosome 4 is described. In addition, this child had renal insufficiency, which is found rarely in association with the 4p(--) syndrome. Previous reports of this syndrome have described only isolated gross structural abnormalites of the urinary tract. In the case discussed here, we present clinical and functional data which indicate that this patient had bilateral renal dysplasia.  (+info)

Genomic instability and recurrent breakpoints are main cytogenetic findings in Hodgkin's disease. (7/1486)

BACKGROUND AND OBJECTIVE: Successful cytogenetic studies in Hodgkin's disease (HD) are rare, and, except for hyperdiploidy, no chromosome changes typical for this disorder have been described. The purpose of this study was to collect cytogenetic information from a new series of lymphoid neoplasms diagnosed either as classical HD or as Hodgkin's-like anaplastic large cell lymphoma (HD-like ALCL), according to the REAL Classification. DESIGN AND METHODS: We studied 27 cases of HD and 10 cases of HD-like ALCL. Cytogenetic investigations were performed on lymph nodes (35 cases), bone marrow or pleural effusion. A large screening of slides was performed to detect abnormal metaphases despite the low mitotic index of Reed-Sternberg cells. In addition to ours, available published data were analyzed in detail to identify recurring cytogenetic events. RESULTS: Metaphases which could be analyzed were obtained in 86.5% of cases, with 59.4% showing abnormal clones. We found a peculiar kind of cytogenetic instability in which, despite variations in the type of structural rearrangements, chromosome breakpoints were non-randomly distributed. Moreover, from our data plus those collected from literature on HD (total 177 cases), the number of breakpoints was higher in patients in a more advanced clinical stage. INTERPRETATION AND CONCLUSIONS: Cytogenetic studies in HD are highly informative regarding clonality, provided large numbers of metaphases are examined. Based on karyotype, genetic changes in HD and HD-like ALCL are similar. Results are consistent with a high degree of chromosomal instability and predominance of hyperdiploid complex karyotypes. Chromosome breakpoints are non-randomly distributed and more numerous in advanced clinical stages.  (+info)

The 'Mickey Mouse' sign and the diagnosis of anencephaly in early pregnancy. (8/1486)

OBJECTIVES: To assess the sonographic screening for anencephaly in the first trimester in a low-risk obstetric population. METHODS: Since 1994, 5388 women attended our clinic for a first-trimester scan (11-14 weeks of gestation) and screening for structural and chromosomal abnormalities. The patients underwent transabdominal scanning, and transvaginal scanning if necessary. RESULTS: The ultrasonographic appearances of anencephaly in the first trimester are different from the familiar second-trimester signs. The cerebral hemispheres are present and exposed to the surrounding amniotic fluid. The ultrasound appearances in the coronal section of the head are best described as 'Mickey Mouse face'. There were six cases of anencephaly (incidence 1.1:1000). All cases were diagnosed in the first trimester and five demonstrated this sign. There were no false-positive diagnoses. The crown-rump length was significantly reduced in all affected fetuses. CONCLUSION: First-trimester ultrasonographic diagnosis of anencephaly is accurate, but sonographers should be familiar with the ultrasound appearances that are different from those in the second trimester.  (+info)

OBJECTIVE: This study aimed at determining the relationship between fetal chromosomal disorders (CDs), including trisomy 21 (T21), and on first-and second-trimester maternal blood plasma, to identify the time-course metabolic adaptations to the conditions and the possible new plasma biomarkers. Furthermore, a definition of a joint circulatory (plasma) and excretory (urine) metabolic description of second-trimester CDs was sought. STUDY DESIGN: Plasma was obtained for 119 pregnant women: 74 controls and 45 CD cases, including 22 T21 cases. Plasma and lipid extracts (for T21 only) were analyzed by nuclear magnetic resonance spectroscopy, and data were handled by variable selection and multivariate analysis. Correlation analysis was used on a concatenated plasma/urine matrix descriptive of second-trimester CD, based on previously obtained urine data. RESULTS: CD cases were accompanied by enhanced lipid beta-oxidation (increased ketone bodies) and underutilization of glucose, pyruvate, and citrate. Lower

What are chromosomal disorders with immune deficiency? These disorders occur when there are missing, extra, or irregular parts of a persons chromosomal DNA. When associated with immune deficiency, chromosomal disorders may be linked to Down syndrome, CHARGE syndrome, DiGeorge Syndrome, and Cornelia de Lange syndrome, abnormalities of chromosomes 8 or 18.
Structural chromosome abnormalities occur when there is a change in the structure or parts of a chromosome. The total number of chromosomes is typically 46 total per cell. Structural chromosome abnormalities occur when part of a chromosome is missing, a part of a chromosome is extra, or a part has switched places with another part. Ultimately, this leads to having too much or too little genetic material. This is a cause of some birth defects.. Each chromosome has many segments. These are usually divided into a short arm and a long arm of the chromosome. The short arm, which is the upper half of the chromosome, is known as the p arm. The long arm, which is the lower half of the chromosome, is the q arm. The centromere is the center part of a chromosome that appears pinched between the p and q arms.. ...

Humans typically have 22 pairs of autosomal chromosomes in their cells, and a pair of sex chromosomes. About 2.7 million individuals have an extra, 47th autosomal chromosome called a small supernumerary marker chromosome (sSMC). These small supernumerary marker chromosomes can originate from any of the 24 different human chromosomes. About 70% of the cases with sSMC are de novo (new mutations), 30% are inherited within a family. About 30% of the carriers of a sSMC are clinically abnormal. The main problem in connection with a sSMC appears when the diagnosis of the presence of a sSMC is made prenatally. Until recently there was no possibility to make clear predictions about the outcome of the pregnancy. However, research is being carried out into the link between the presence of a sSMC in individuals and any consequent symptoms. Liehr et al. Small supernumerary marker chromosomes (sSMC) in humans.

Non-invasive prenatal screening (NIPS) for fetal chromosome abnormalities using cell-free deoxyribonucleic acid (cfDNA) in maternal serum has significantly influenced prenatal diagnosis of fetal aneuploidies since becoming clinically available in the fall of 2011. High sensitivity and specificity have been reported in multiple publications, nearly all of which have been sponsored by the commercial performing laboratories. Once results are returned, positive and negative predictive values (PPVs, NPVs) are the performance metrics most relevant to clinical management. The purpose of this report is to present independent data on the PPVs of NIPS in actual clinical practice. Charts were retrospectively reviewed for patients who had NIPS and were seen March 2012 to December 2013 in a tertiary academic referral center. NIPS results were compared to diagnostic genetic test results, fetal ultrasound results, and clinical phenotype/outcomes. The PPV was calculated using standard epidemiological methods.

The high accuracy of the PrenaTest® has been proven in clinical studies. Test accuracies of more than 99% were achieved, depending on the chromosomal disorder tested. This number means that out of 100 pregnant women whose unborn child is affected by a chromosomal disorder, 99 will be determined correctly. In addition, the probability that an abnormal (that is, positive) test result is not correct is very low. This is indicated by the so-called false-positive rate of 0.1%. This value implies that in a group of 1000 unaffected pregnant women, one pregnant woman will receive an abnormal (that is, positive) test result, although her unborn child is in fact not affected by a chromosome disorder. It is important for you to know that 100% test accuracy should not be expected when non-invasive prenatal tests are used. In rare cases, there may be no or an unclear test result. However, this does not reveal anything about the health of your child. You may then repeat the PrenaTest® at no additional cost. ...
Its more than just the number of miscarriages that determines the likelihood of structural chromosome abnormalities, say researchers from the Netherlands. In couples who are trying to conceive and who have had two or more miscarriages, young maternal age at the time of a second miscarriage, a history of three or more miscarriages, and a history of two or more miscarriages in siblings or parents of either partner make the couple more likely to be carriers of such anomalies, according to the results of a nested case-control study.

The report that has inspired this communication addresses basic side of chromosome mosaicism research. However, Molecular Cytogenetics has published a series of original researches, which have paid attention to practical side of chromosomal mosaicism [31-36]. These have demonstrated that chromosomal mosaicism is an appreciable phenomenon frequently encountered in small supernumerary marker chromosomes (sSMC) research [31-33, 35]. Furthermore, it provided evidences that mosaic structural chromosome rearrangements are likely to occur more frequently, than previously recognized [4, 5, 34, 36]. In the light of studying sSMC, it should be additionally mentioned that chromosomal mosaicism could be cryptic [37, 38] and dynamic [39]. The former is referred to as occurrence of more complex mosaics than revealed after karyotyping [37]. The latter is the occurrence of new genetic imbalances from an already abnormal cell or mosaicism resulting from behavioral peculiarities of a rearranged chromosome [39]. ...

Chromosome anomalies may result from abnormalities in number or structure. Abnormalities of chromosome number include polyploidy and autosomal and sex chromosome aneuploidy. Aneuploidy refers primarily to monosomy (the presence of only one copy of a chromosome in an otherwise diploid cell) and trisomy (three copies of a chromosome). Abnormalities of chromosome structure consist primarily of translocations (interchange of genetic material between nonhomologous chromosomes); deletions (caused by a chromosome break and subsequent loss of genetic material); and duplications (i.e., partial trisomy of genetic material).1 The classic belief that karyotype is sufficient to rule-out chromosomal anomalies applies only to chromosomal anomalies related to number. Structural anomalies do not fit this scenario and often require more detailed investigation. Therefore, for some syndromes, it is important to first recognize the disorder clinically in order to facilitate correct genetic testing. ...
Background Approximately 50% of spontaneous miscarriages are associated with chromosome abnormalities. Identification of these karyotypic abnormalities helps to estimate recurrence risks in future pregnancies. Chromosomal microarray analysis (CMA) is transforming clinical cytogenetic practice with its ability to examine the human genome at increasingly high resolution. Objectives The aim of this study was to determine whether…
The overall significance of this study is to develop a laboratory developed test (LDT) to use a new marker in the maternal blood to better identify pregnancies that have a child with a chromosome abnormality such as Down syndrome (trisomy 21), Edwards syndrome (trisomy 18), Patau syndrome (trisomy 13), Klinefelter syndrome, (47, XXY), and other chromosome abnormalities. Accomplishing that task would reduce the need for invasive amniocentesis and CVS procedures ...

Trisomy 18 syndrome is a rare chromosomal disorder in which all or a large portion of chromosome 18 is present three times (trisomy), rather than twice in each cell of the body. This extra copy changes how the babys body and brain develop, which can cause distinctive physical features, structural birth defects and developmental disabilities. Chromosome abnormalities are usually present at conception, the result of errors in egg or sperm formation. In rare cases chromosome abnormalities are inherited. The majority of babies born with trisomy 18 are female. Trisomy 18 can be diagnosed prenatally by amniocentesis or chorionic villus sampling. One factor that increases the risk for having a baby with trisomy 18 is the mothers age. Women who are 35 years or older when they become pregnant are more likely to have a pregnancy affected by trisomy 18 than women who become pregnant at a younger age.. ...
Lucas diagnosis of Partial Trisomy 13 (PT13) is extremely rare! While the typical human has two chromosomes, an individual with a chromosomal disorder has an extra chromosome (full or partial) present.
