Chromosomal abnormalities have been identified as the main cause of developmental delay, mental retardation, autistic spectrum disorders as well as multiple congenital abnormalities. Until recently, the only available method of detecting chromosomal abnormalities was conventional G-banding karyotype, which screens all chromosomes for aneuploidy and segmental lesions up to the limit of 5-10 Mb.. Chromosomal microarray analysis with molecular karyotype (aCGH) is a new method that enables the detection of chromosomal abnormalities that are accompanied by a change in the copy number of genetic loci (aneuploidy, deletions, duplications) across the entire genome of a patient, with an effective resolution of up to 50Kb.. Numerous studies have shown the benefits of applying molecular karyotype to patients with developmental delay and multiple congenital abnormalities of unknown etiology, leading to the establishment of molecular karyotype as the first tier test for these patients. In particular, it has ...

Background: Various genetic technologies have been employed in the identification of genomic complexity and refinement of prognostic classification of clinically heterogeneous disease of chronic lymphocytic leukemia (CLL). Objective: The present study of interphase cytogenetics and conventional karyotyping was undertaken to perform comprehensive analysis of CLL genetics with an approach to refine early prognostication of disease. Material & Methods: Retrospective analysis by fluorescence in situ hybridization (FISH) was carried out on total 671 patients of CLL at diagnosis between 2008 and 2015. Conventional cytogenetics studies were performed in 50 of 671 patients using CPG Oligonucleotide + IL-2 and TPA (12-O-Tetradecanyl Phorbol 13-acetate) for stimulation of lymphocytes cultures. Results: Interphase cytogenetics could detect recurrent abnormalities such as del(13q14), +12, del(17p13), del(11q22), del(6q23) in 71% of cases. The incidence of del(13q) was higher in Rai stage 0, I, II (p = 0.0005);

Mosaic structural chromosomal abnormalities observed along the trophoblast-mesenchyme-fetal axis, although rare, pose a difficult problem for their prognostic interpretation in prenatal diagnosis. Additional issues are raised by the presence of mosaic imbalances of the same chromosome showing different sizes in the different tissues, that is, deletions and duplications in the cytotrophoblast and mesenchyme of chorionic villi (CV). Some of these cytogenetic rearrangements originate from the post-zygotic breakage of a dicentric chromosome or of the product of its first anaphasic breakage. Selection of the most viable cell line may result in confined placental mosaicism of the most severe imbalance, favoring the presence of the cell lines with the mildest duplications or deletions in the fetal tissues. We document three cases of ambiguous results in CV analysis due to the presence of different cell lines involving structural rearrangements of the same chromosome which were represented differently ...

We live in a digital era in which speed and knowledge turnover are very high. In this scenario, patients and physicians desire faster but precise diagnostic tests at a low cost.. Chronic myeloid leukemia (CML) is characterized by the presence of t(9;22)(q34.1;q11.2), the Philadelphia (Ph) chromosome, or the breakpoint cluster region-Abelson murine leukemia 1 (BCR-ABL1) rearrangement.1 The diagnosis can be made using findings from peripheral blood (PB) exams combined with the detection of the Ph chromosome by karyotyping using a bone marrow (BM) sample or testing for the BCR-ABL1 by real time quantitative polymerase chain reaction (RqPCR) in PB or BM samples.. Comparing karyotyping with RqPCR, the former is a time consuming process that takes around 15 days while one gets the results of RqPCR in seven days. Furthermore, karyotyping is more expensive and performed after marrow aspiration whereas RqPCR may be carried out using PB. Therefore, some patients and doctors opt for the faster and cheaper ...

Studies have shown that a majority of pregnancies that end in miscarriage are due to a chromosome abnormality usually involving a duplicated or missing chromosome. Often this happens by chance and is not likely to occur in future pregnancies. For many women, a miscarriage can be a traumatic experience and can cause feelings of loss and grief. The option of genetic testing, such as karyotyping, may offer an explanation for the miscarriage and may help some women find closure in their loss. However, no literature exists on a womens experience with genetic testing following a miscarriage. This assumption that the knowledge that can be gained from karyotyping may be a positive experience for a woman following a miscarriage should be studied and the results published. This study will address whether routine karyotyping should be offered following a miscarriage for the purpose of benefiting the patients experience. ...

Molecular karyotypes of H. bogdanii Wilensky, 1918 (2n = 14), and H. brevisubulatum Link, 1844 ssp. brevisubulatum (2n = 28), were characterized by physical mapping of several repetitive sequences. A total of 18 repeats, including all possible di- or trinucleotide SSR (simple sequence repeat) motifs and satellite DNAs, such as pAs1, 5S rDNA, 45S rDNA, and pSc119.2, were used as probes for fluorescence in situ hybridization on root-tip metaphase chromosomes. Except for the SSR motifs AG, AT and GC, all the repeats we examined produced detectable hybridization signals on chromosomes of both species. A detailed molecular karyotype of the I genome of H. bogdanii is described for the first time, and each repetitive sequence is physically mapped. A high degree of chromosome variation, including aneuploidy and structural changes, was observed in H. brevisubulatum. Although the distribution of repeats in the chromosomes of H. brevisubulatum is different from that of H. bogdanii, similar patterns between the two

Authors: HAMID REZA ESMAEILI, ZEINAB PIRAVAR, A.H. SHIVA Abstract: The karyotypes of 2 endemic tooth-carps of Iran, Aphanius persicus (Jenkis, 1910) and Aphanius sophiae (Heckel, 1849), were investigated by examining metaphase chromosomes spreads obtained from gill epithelial and kidney cells. The diploid chromosome numbers of both species were 2n = 48. The karyotypes consisted of 11 pairs of submetacentric and 13 pairs of subtelocentric chromosomes in A. persicus and 14 submetacentric and 10 subtelocentric chromosomes in A. sophiae. The arm numbers in A. persicus and A. sophiae were NF = 70 and NF = 76, respectively. Sex chromosomes were cytologically indistinguishable in both tooth-carps.

Chromosome studies. Chromosomes are the threadlike structures of DNA in every cell in our bodies that contain our genes. Cytogenetics is a word used to describe the study of chromosomes. The chromosomes need to be stained in order to see them with a microscope. When stained, the chromosomes look like strings with light and dark bands. A picture (an actual photograph from one cell) of all 46 chromosomes, in their pairs, is called a karyotype. A normal female karyotype is written 46, XX, and a normal male karyotype is written 46, XY. The standard analysis of the chromosomal material evaluates both the number and structure of the chromosomes, with an accuracy of over 99.9 percent. Chromosome analyses are usually performed using a blood sample, prenatal specimen, skin biopsy, or other tissue sample. Chromosomes are analyzed by specially trained healthcare personnel that have advanced degrees in cytogenetic technology and genetics. Chromosome studies may be performed when a child is born with ...

Despite significant advances in molecular genetic approaches, fluorescence in situ hybridization (FISH) remains the gold standard for the diagnostic evaluation of genomic aberrations in patients with chronic lymphocytic leukemia (CLL). Efforts to improve the diagnostic utility of molecular cytogenetic testing have led to the expansion of the traditional 4-probe CLL FISH panel. Not only do these efforts increase the cost of testing, they remain hindered by the inherent limitations of FISH studies - namely the inability to evaluate genomic changes outside of the targeted loci. While array-based profiling and next generation sequencing (NGS) have critically expanded our understanding of the molecular pathogenesis of CLL, these methodologies are not routinely used by diagnostic laboratories to evaluate copy number changes or the mutational profile of this disease. Mitogenic stimulation of CLL specimens with CpG-oligonucleotide (CpG-ODN) has been identified as a reliable and reproducible means of ...

Subjects and cell preparation. Sixty-one new patients with adult de novo AML, who were diagnosed according to the French-American-British criteria, were the subjects of this study. Their respective French-American-British subtypes were 18 M1, 16 M2, 8 M3, 9 M4, 8 M5, and 2 M6. Cytogenetic data obtained by the standard Giemsa banding method were classified into three prognostic categories, which were defined previously based on other reports (24-26). That is, favorable is the presence of inv(16), t(15;17), or t(8;21), both with and without any other abnormality; unfavorable is −5, −7, 5q−, 7q−, t(9;22), abnormalities of chromosomes 3q and/or 11q, and a complex karyotype (,3 chromosomal abnormalities); and intermediate is all other karyotypes. In the present cohort, there were no patients with t(9;22). The prognosis did not differ between patients with and without additional abnormalities in the favorable cytogenetics group.

We have shown that constitutive c-Myc overexpression reproducibly immortalizes HFFs isolated from several independent donors. In rodent cells and other strains of human fibroblasts, acute activation of the MycER chimera caused the appearance of karyotypic abnormalities, including gross chromosomal rearrangements (32, 33). c-Myc-immortalized HFFs exhibited a normal karyotype (Fig. 3C), although they did show signs of increased DNA damage as seen by staining with anti-γ-H2AX foci (data not shown), indicating that these cells can efficiently repair genomic damage. Because stable chromosomal rearrangements were not selected for during immortalization (Fig. 3C), we hypothesize that cells with karyotypic abnormalities are likely not favored for survival. c-Myc-immortalized human prostate epithelial cells (24), similar to our findings, had no karyotypic abnormalities; however, they had lost the ability to respond to p16-mediated arrest. This finding is different from our observation (Fig. 5), and the ...

Karyotyping analyzes all 23 pairs of chromosome but requires cells from the miscarriage tissue to first be grown in the laboratory, a process called cell culture. For this reason requirement, tissue that is passed at home is often unable to be tested with this particular method. About 20% or more of miscarriage samples fail to grow and thus no email address details are available. Additionally, karyotyping is unable to tell the difference between cells from the mother (maternal cells) and cells from the fetus. If a normal female result is available, it may be the correct result for the fetus or it might be maternal cell contamination (MCC) where the result actually originates from testing the mothers cells present in the pregnancy tissue rather than the fetal cells. MCC seems to occur in about 30% or more of the samples tested by traditional karyotype. Results from karyotyping usually take a few weeks to months another from the laboratory ...

The sample is placed into a special dish or tube and allowed to grow in the laboratory. Cells are later taken from the new sample and stained. The laboratory specialist uses a microscope to examine the size, shape, and number of chromosomes in the cell sample. The stained sample is photographed to show the arrangement of the chromosomes. This is called a karyotype. Certain problems can be identified through the number or arrangement of the chromosomes. Chromosomes contain thousands of genes that are stored in DNA, the basic genetic material. ...

Except for one tumor with an apparently normal chromosomal constitution, clonal chromosome abnormalities were detected in all examined cases by the combined approach. The application of SKY and FISH techniques improved the karyotypic descriptions, originally based on C-banding only, by identifying 32 additional numerical changes, by establishing the chromosomal origin of 27 markers and 2 ring chromosomes, by redefining 53 aberrations and by detecting 15 hidden chromosomal rearrangements. No recurrent translocation, however, was detected. The most prominent: karyotypic feature was thus the occurrence of deletions and losses of whole chromosome copies indicating the importance of tumor suppressor genes in ...

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.

Chromosomal abnormalities are diagnostic and prognostic key factors in acute myeloid leukemia (AML) patients, as they play a central role for risk stratification algorithms. High hyperdiploidy (HH), a rare cytogenetic abnormality seen commonly in elder male AML patients, is normally categorized under AML with complex karyotype (CK). Accordingly, patients with HH generally are associated with low remission rates and a short overall survival. Here we report a case of 21-year-old female, diagnosed with a de novo AML-M1 according to WHO classification and a CK at diagnosis. Cytogenetic, molecular cytogenetic approaches (standard fluorescence in situ hybridization (FISH), array-proven multicolor banding (aMCB)) and high resolution array comparative genomic hybridization (aCGH) analyses revealed a unique complex but still near diploid karyotype involving eleven chromosomes was identified. It included pentasomy 4, three yet unreported chromosomal aberrations t(1;2)(p35;p22), t(1;3)(p36.2;p26.2), and t(10;12)

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]. ...

Various approaches are used to study the chromosomal makeup of cells. Traditional cytogenetic methods are based on the analysis of mitotic cells fixed onto slides to analyze their chromosomal composition (karyotype) by microscopy. This approach can be combined with FISH to detect specific sequences on morphologically distinct individual chromosomes. Disadvantages of this type of microscopic analysis are the amount of time and labor required to acquire and analyze typically less than a hundred cells. As a result, the statistical power of this type of analysis is limited. An alternative to traditional cytogenetic methods is flow karyotyping (1,2) a method to analyze chromosomes in suspension by flow cytometry. For bivariate flow karyotyping, the DNA composition of specific chromosomes in suspension is measured based on the DNA-specific dyes Hoechst 33258 and chromomycin A3 (3,4). In our protocol, we combine flow karyotyping and FISH to analyze repetitive DNA in individual chromosomes by flow ...

Myelodysplastic syndrome (MDS) patients with a normal karyotype constitute a heterogeneous group from a biological standpoint and their outcome is often unpredictable. Interphase fluorescence in situ hybridization (I-FISH) studies could increase the rate of detection of abnormalities, but previous reports in the literature have been contradictory. We performed I-FISH and conventional karyotyping (G-banding) on 50 MDS patients at diagnosis, after 6 and 12 months or at any time if a transformation to acute myeloid leukemia (AML) was detected. Applying a probe-panel targeting the centromere of chromosomes 7 and 8, 5q31, 5p15.2 and 7q31, we observed one case with 5q deletion not identified by G-banding. I-FISH at 6 and 12 months confirmed the karyotype results. Eight cases transformed to AML during follow-up, but no hidden clone was detected by I-FISH in any of them. The inclusion of I-FISH during follow-up of MDS resulted in a small improvement in abnormality detection when compared with ...

RESULTS Table shows patients sex, age, date of diagnosis, karyotype at diagnosis, FISH at diagnosis, date of BMT, donors sex, and karyotype and FISH at one year after BMT. It was possible to compare the results of karyotyping and FISH at diagnosis and one year after transplantation. At diagnosis, 10 patients presented Ph chromosome by cytogenetics and two (11 and 12) did not show metaphases that could be studied. FISH was positive in all except 2 (6 and 8), whose samples did not have enough cells for analysis. Cases that did not present cytogenetic results (11 and 12) presented positive BCR/ABL rearrangement by FISH. The percentage of cells with BCR/ABL rearrangement by FISH at diagnosis varied from 66 to 98%, with a mean of 81.25%. One year after transplantation, karyotyping was not possible in 3 cases (3, 6 and 9) due to lack of metaphases. In eight cases (2, 4, 5, 7, 8, 10, 11 and 12), the karyotype was normal while one patient (1) had persistence of the Ph chromosome. Two cases (4 and 8) ...

Karyotype data are the most common form of genetic data that is regularly used clinically. They are collected as part of the standard of care in many diseases, particularly in pediatric and cancer medicine contexts. Karyotypes are represented in a unique text-based format, with a syntax defined by the International System for human Cytogenetic Nomenclature (ISCN). While human-readable, ISCN is not intrinsically machine-readable. This limitation has prevented the full use of complex karyotype data in discovery science use cases. To enhance the utility and value of karyotype data, we developed a tool named CytoGPS. CytoGPS first parses ISCN karyotypes into a machine-readable format. It then converts the ISCN karyotype into a binary Loss-Gain-Fusion (LGF) model, which represents all cytogenetic abnormalities as combinations of loss, gain, or fusion events, in a format that is analyzable using modern computational methods. Such data is then made available for comprehensive downstream analyses that ...

In countries where comparative genomic hybridization arrays (aCGH) and next generation sequencing are not widely available due to accessibility and economic constraints, conventional 400-500-band karyotyping is the first-line choice for the etiological diagnosis of patients with congenital malformations and intellectual disability. Conventional karyotype analysis can rule out chromosomal alterations greater than 10 Mb. However, some large structural abnormalities, such as derivative chromosomes, may go undetected when the analysis is performed at less than a 550-band resolution and the size and banding pattern of the interchanged segments are similar. Derivatives frequently originate from inter-chromosomal exchanges and sometimes are inherited from a parent who carries a reciprocal translocation. We present two cases with derivative chromosomes involving a 9.1 Mb 5p deletion/14.8 Mb 10p duplication in the first patient and a 19.9 Mb 5p deletion/ 18.5 Mb 9p duplication in the second patient. These long

Intraspecific variation in chromosome structure may cause genetic incompatibilities and thus provides the first step in the formation of species. In ants, chromosome number varies tremendously from 2n = 2 to 2n = 120, and several studies have revealed considerable variation in karyotype within species. However, most previous studies were limited to the description of chromosome number and morphology, and more detailed karyomorphometric analyses may reveal additional, substantial variation. Here, we studied karyotype length, genome size, and phylogeography of five populations of the fungus-farming ant Trachymyrmex holmgreni in order to detect potential barriers to gene flow. Chromosome number and morphology did not vary among the five populations, but karyotype length and genome size were significantly higher in the southernmost populations than in the northern populations of this ant. Individuals or colonies with different karyotype lengths were not observed. Karyotype length variation appears to result

The development of a universal soybean (Glycine max [L.] Merr.) cytogenetic map that associates classical genetic linkage groups, molecular linkage groups, and a sequence-based physical map with the karyotype has been impeded due to the soybean chromosomes themselves, which are small and morphologically homogeneous. To overcome this obstacle, we screened soybean repetitive DNA to develop a cocktail of fluorescent in situ hybridization (FISH) probes that could differentially label mitotic chromosomes in root tip preparations. We used genetically anchored BAC clones both to identify individual chromosomes in metaphase spreads and to complete a FISH-based karyotyping cocktail that permitted simultaneous identification of all 20 chromosome pairs. We applied these karyotyping tools to wild soybean, G. soja Sieb. and Zucc., which represents a large gene pool of potentially agronomically valuable traits. These studies led to the identification and characterization of a reciprocal chromosome ...

Among other genetic causes of both female and male infertility there are small supernumerary marker chromosomes. Small supernumerary marker chromosomes (sSMC) are structurally abnormal chromosomes that cannot be unambiguously identified by sequencing or banding cytogenetics. The implication of sSMC in infertility could be due to a partial trisomy of some genes but also to mechanical effects perturbing meiosis. To identify sSMC it is necessary to proceed to chromosomal analysis by high definition karyotyping and/or FISH.. Breda Genetics panel recommended for this condition (EXOME PANEL):. Female infertility (AR, BMP15, BRCA1, CYP21A2, DHEAST, DIAPH2, FIGLA, FMR1, FOXL2, FSHR, HFM1, LHB, LHCGR, MCMDC1, MCM8, NOBOX, NR5A1, POF1B, PSMC3IP, SHBG, SRD5A1, SRD5A2, STAG3, TUBB8). plus.

The deletion of 5q is a frequent chromosomal abnormality in patients with MDS. When detected in association with complex karyotype, the 5q- aberration is associated with adverse prognostic outcome. Although not contained within any common deleted region on 5q, NPM1 can be deleted in 5q- cases with large chromosomal deletions. To investigate haploinsufficiency of NPM1 in myeloid malignancies with 5q- aberration, we analyzed the NPM1 gene in terms of mutational and methylation status and presence of deletions in 53 patients with MDS or secondary AML (sAML) carrying the 5q- abnormality as a sole chromosomal alteration or associated with additional chromosome defects. NPM1 deletion, hypermethylation, or mutations were not found in any of the 23 patients with isolated 5q- while loss of one copy of NPM1 was found in 7/30 patients with 5q- associated with complex karyotype. ...

Bovine karyotyping has become an important diagnostic tool in animal breeding. In the prenatal period it can diagnose several chromosomal abnormalities such as Robertsonian translocations, testicle feminization syndrome, gonadal dysgenesis and Klinefelters syndrome. An important cell source for karyotype analysis is the amniotic fluid. It has been extensively used in humans but in bovine, however, this is not the case despite its diagnostic value. Since a small percentage of cells is viable, cells and their growth conditions as well as the handling of the material should be optimal to insure a successful analysis. For this, we have compared the growth efficiency for bovine amniocytes in two media, employing cells from 10 to 14 weeks of gestation. Amniocytes were cultured in the Amniomax (Gibco-BRL/ Life Technologies, Rockville, MD USA) medium during eleven days and in the RPMI 1640 (Gibco-BRL) medium during sixteen days at 37ºC and 5% CO2, then fixed and GTG banded. All the cultures with RPMI ...

article{ffe9e1ae-909d-427e-8e29-66e3cbc0e09f, abstract = {The cytogenetic features (ploidy, complexity, breakpoints, imbalances) were ascertained in 783 abnormal multiple myeloma (MM) cases to identify frequently involved chromosomal regions as well as a possible impact of age/sex. The series included MM patients from the Mitelman Database of Chromosome Aberrations in Cancer and from our own laboratory. Hyperdiploidy was most common, followed by hypodiploidy, pseudodiploidy and tri-/tetraploidy. Most cases were complex, with a median of eight changes per patient. The distribution of modal numbers differed between younger and older patients, but was not related to sex. No sex- or age-related differences regarding the number of anomalies were found. The most frequent genomic breakpoints were 14q32, 11q13, 1q10, 8q24, 1p11, 1q21, 22q11, 1p13, 1q11, 19q13, 1p22, 6q21 and 17p11. Breaks in 1p13, 6q21 and 11q13 were more common in the younger age group. The most frequent imbalances were + 9, - 13, + ...

A karyotype a complete set of chromosomes of a particular species. The number and appearance of chromosomes can very dramatically between different organisms. Human beings have 46 chromosomes, 22 pairs of autosomal chromosomes and one pair of sex chromosomes. The latter is what determines whether a developing embryo develops as a physiological male or female, with a male karyotype displaying the diminutive Y chromosome beside its larger X chromosome partner (women have two X chromosomes in their karyotype).. A karyotype is generally an image of a completed and arranged set of chromosomes as viewed through a light microscope. A chromosome set can be attained from nearly any type of tissue.[1] Dividing cells are stained with a special dye, usually the Giemsa stain, and then cell division is halted during metaphase. An image of the dividing cells is taken when the chromosomes are all visible, and the individual chromosomes are cut out of the picture and rearranged on a separate medium based on ...

A karyotype test is basically a test that analyses your chromosomes. It tells you how many chromosomes a person has and looks at the structure of each chromosome individually and allows us to determine whether your embryos need additional screening before they are selected for implantation.. A karyotype can be performed on any tissue but most often it is done from a blood sample, a sample of amniotic fluid or a piece of placenta obtained through chorionic villi sampling. Karyotyping is a complex process that involves growing the cells, obtaining the chromosomes, staining and analysing the chromosomes and reporting the results. A karyotype is an actual photograph of the chromosomes from one cell.. We check the chromosome set of both partners to exclude the possibility of underlying chromosomal rearrangement problem and, from the patients perspective; a karyotype is usually a simple blood test. It is what happens to the blood after it is collected that is actually quite complex.. Sometimes a part ...

Introduction: One of the important causes of male infertility is aberration at the chromosomes. Aim: The main purpose of this study was to determine the frequency and types of chromosomal aberration in infertile/sterile men whose samples were analyzed in the Center for Cytogenetics of Faculty of Medicine University of Sarajevo in the last four years. Methods: A total of 353 infertile/sterile men, between the ages of 22-55 years, referred for cytogenetic analysis to the Center for Genetics of Faculty of Medicine during the period 2013-2016. Karyotyping was performed on peripheral blood lymphocytes by using the Giemsa trypsin banding (GTG) technique. Results: The structural and numerical chromosomal aberration in infertility/ sterility of men found with the incidence of 6% (20/353). Out of the 20 patients with abnormal cytogenetic diagnosis, structural chromosome abnormalities were observed in 17 (85%) patients and 3 (15%) with numerical aberrations. The type of aberrations mostly found were ...

A testing method that makes a certain characteristic of chromosomes easier to see. A karyotype is the systematic arrangement, using images, of the 46 human chromosomes of a cell. Karyotypes are examined for deviations from the expected arrangement, number, size, shape or other characteristics of the chromosomes. Each chromosome pair has a characteristic banding pattern. To make the banding pattern easier to see, a dye called Giemsa may be used as a stain. This process is also referred to as G-banding. G-banding karyotyping and other cytogenetic tests provide doctors with information that contributes to determining the best treatment approach for an individual patient. The test takes longer than the FISH test, but has the advantage of being able to detect any changes that are visible because it does not rely on specific probes. Usually, both tests are done on samples from the marrow, especially at the time of diagnosis.. ...

Cytogenetic studies were performed in 95 adults with acute leukemia, 39 (41%) of whom had abnormal karyotypes in their leukemic cells. The karyotypes were grouped according to the Denver-Chicago classification, and abnormalities were correlated with clinical variables. The frequency and quality of abnormality was not influenced by age, morphologic type of leukemia, or prior treatment. The frequency of abnormal karyotypes was increased in patients with increasing leukocytosis. Hypodiploidy adversely affected response to treatment and survival. D or E group chromosome deletions were associated with a decreased response to treatment and survival, whereas patients with extra D or E chromosomes had an improved prognosis. The overall distribution of chromosomal abnormalities in the leukemic cells deviated significantly from the expected for random distribution. D+, E+, and G- abnormalities were significantly more frequent than expected. Patients with marrow leukemic cell aneuploidy showed a loss of ...

Giant neutrophils derived from tetraploid leukemic clone in an acute myeloblastic leukemia: cytofluorometric study.: Near-tetraploid chromosomes were observed i

Nowadays the role of genetic findings in determining the diagnosis, therapy and prognosis of acute myeloid leukemia (AML) has become more valuable. To improve and validate the detection of clonal chromosomal aberrations in leukemia, we designed a combined application of karyotyping with multiplex reverse transcription-polymerase chain reaction (RT-PCR) and fluorescence in situ hybridization (FISH), and addressed the expression and distribution of fusion genes among the subtypes of Chinese adult patients with de novo AML. Multiplex RT-PCR assays were performed on 477 samples from newly diagnosed AML patients, and cytogenetic data were obtained from 373 of them by R or G banding techniques and those in some cases were confirmed by FISH. The PCR products in some suspected cases were tested by two-directional sequencing. The results showed that except unqualified samples, fusion genes were detected by multiplex RT-PCR in 211 of 474 patients (44.51%), including AML1-ETO, CBFβ-MYH11, PML-RARα, ...
