Cardiac and gastrointestinal malformations, a marked increase in the incidence of LEUKEMIA, and the early onset of ALZHEIMER DISEASE are also associated with this condition. Pathologic features include the development of NEUROFIBRILLARY TANGLES in neurons and the deposition of AMYLOID BETA-PROTEIN, similar to the pathology of ALZHEIMER DISEASE.

The functional hereditary units of INSECTS.
Single-stranded complementary DNA synthesized from an RNA template by the action of RNA-dependent DNA polymerase. cDNA (i.e., complementary DNA, not circular DNA, not C-DNA) is used in a variety of molecular cloning experiments as well as serving as a specific hybridization probe.
The prophase of the first division of MEIOSIS (in which homologous CHROMOSOME SEGREGATION occurs). It is divided into five stages: leptonema, zygonema, PACHYNEMA, diplonema, and diakinesis.
A characteristic showing quantitative inheritance such as SKIN PIGMENTATION in humans. (From A Dictionary of Genetics, 4th ed)
A method for ordering genetic loci along CHROMOSOMES. The method involves fusing irradiated donor cells with host cells from another species. Following cell fusion, fragments of DNA from the irradiated cells become integrated into the chromosomes of the host cells. Molecular probing of DNA obtained from the fused cells is used to determine if two or more genetic loci are located within the same fragment of donor cell DNA.
A large collection of DNA fragments cloned (CLONING, MOLECULAR) from a given organism, tissue, organ, or cell type. It may contain complete genomic sequences (GENOMIC LIBRARY) or complementary DNA sequences, the latter being formed from messenger RNA and lacking intron sequences.
The presence of apparently similar characters for which the genetic evidence indicates that different genes or different genetic mechanisms are involved in different pedigrees. In clinical settings genetic heterogeneity refers to the presence of a variety of genetic defects which cause the same disease, often due to mutations at different loci on the same gene, a finding common to many human diseases including ALZHEIMER DISEASE; CYSTIC FIBROSIS; LIPOPROTEIN LIPASE DEFICIENCY, FAMILIAL; and POLYCYSTIC KIDNEY DISEASES. (Rieger, et al., Glossary of Genetics: Classical and Molecular, 5th ed; Segen, Dictionary of Modern Medicine, 1992)
Enzymes that are part of the restriction-modification systems. They catalyze the endonucleolytic cleavage of DNA sequences which lack the species-specific methylation pattern in the host cell's DNA. Cleavage yields random or specific double-stranded fragments with terminal 5'-phosphates. The function of restriction enzymes is to destroy any foreign DNA that invades the host cell. Most have been studied in bacterial systems, but a few have been found in eukaryotic organisms. They are also used as tools for the systematic dissection and mapping of chromosomes, in the determination of base sequences of DNAs, and have made it possible to splice and recombine genes from one organism into the genome of another. EC 3.21.1.
Congenital conditions of atypical sexual development associated with abnormal sex chromosome constitutions including MONOSOMY; TRISOMY; and MOSAICISM.
Endogenous substances, usually proteins, which are effective in the initiation, stimulation, or termination of the genetic transcription process.

Severe mental retardation in a boy with partial trisomy 10q and partial monosomy 2q. (1/181)

A severely mentally subnormal child with many physical stigmata was shown to have the karyotype 46,XY,-2,+der(2),t(2;10)(q31;q24)pat. Full evaluation of this patient's karyotype depended on the family studies. It was shown that a balanced translocation t(2,10) was present in 4 normal males in 3 generations.  (+info)

Gene dosage: evidence for assignment of erythrocyte acid phosphatase locus to chromosome 2. (2/181)

A child, trisomic for the distal short arm of chromosome 2 due to a familial 2/18 translocation, has elevated levels of activity of erythrocyte acid phosphatase [orthophosphoric-monoester phosphohydrolase (acid optimum),] Ferguson-Smith et al. [(1973) Nature New Biol. 243, 271-274] previously had found decreased levels of activity and loss of expression of an erythrocyte acid phosphatase allele in a subject who lacked one of the two homologous regions containing the distal three bands of chromosome 2. They suggested that the locus for erythrocyte acid phosphatase is located on that segment. Our findings provide further evidence for this assignment and also suggest an in vivo gene dosage effect of this autosomal locus, which depends on both the type and number of alleles present.  (+info)

Assignment of a locus required for flavoprotein-linked monooxygenase expression to human chromosome 2. (3/181)

Hybrid clones segregating human chromosomes were prepared by fusing mouse RAG cells to fresh human bone marrow cells and tested for the mixed-function oxygenase [flavoprotein-linked monooxygenase; RH, reduced-flavoprotein:oxygen oxidoreductase (RH-hydroxylating); EC] arylhydrocarbon hydrocarbon hydroxylase. Neither constitutive nor induced aryl hydrocarbon hydroxylase activity was detected in parental RAG cells. Induced aryl hydrocarbon hydroxylase was expressed in 4 out of 12 primary and 12 out of 19 secondary hybrid clones examined. Constitutive hydroxylase activity was detectable in 9 of the 15 inducible clones. All of the hybrid clones that exhibited constitutive hydroxylase activity were also inducible. There was a positive correlation between constitutive and induced hydroxylase activities although the absolute levels of the enzyme showed a wide range between different clones. Isozyme analysis performed on 12 primary and 19 secondary hybrid clones showed that aryl hydrocarbon hydroxylase activity was concordant with the expression of the human isozymes malate dehydrogenase (EC and isocitrate dehydrogenase (EC, previously assigned to human chromosome 2. Isozyme markers for 19 other human chromosomes segregated independently from aryl hydrocarbon hydroxylase activity. The results suggest that the gene(s) required for aryl hydrocarbon hydroxylase activity are located on human chromosome 2.  (+info)

Loss of Rh antigen associated with acquired Rh antibodies and a chromosome translocation in a patient with myeloid metaplasia. (4/181)

Myeloid metaplasia is a clonal disease of the marrow pluripotent stem cell in which a constant cytogenetic abnormality could result in an altered antigenic characteristic of hematopoietic cells. A 57-yr-old man who had acquired myeloid metaplasia at age 37 was noted to be Rh negative, although blood typing at age 33 was Rh positive. His erythrocytes reacted with anti-c and anti-e, typical for an Rh negative individual. Analysis of 11 metaphase bone marrow cells by G-banding revealed 46 chromosomes with a consistent anomaly in 100% of cells involving chromosomes 1 and 13. The changes were consistent with a reciprocal translocation, with break points at approximately 1p32 and 13q22, although break points at 1p13 and 13q14 were also possible. Since previous cytogenetic data have localized the Rh gene to the short arm of chromosome 1, our data indicate the Rh gene lies within the segment u13 leads to 1p32. Serum of this patient had circulating anti-D and anti-C antibodies. Consequently, this patient lost immunologic tolerance to a "self antigen" after losing the ability to express this antigen.  (+info)

Fanconi's aplastic anaemia with short stature. Absence of response to human growth hormone. (5/181)

A patient with idiopathic marrow hypoplasia associated with short stature and other anomalies (Fanconi's anaemia) is described: treatment with human growth hormone for one year did not accelerate his growth rate or significantly affect his anaemia: androgen treatment considerably improved both features. Endocrine studies suggest that though he had poor and insufficient production of endogenous growth hormone to insulin-induced hypoglycaemia, the major defect in this syndrome is determined more at the end-organ than at the pituitary or gonadal level.  (+info)

Localization of human gene loci using spontaneous chromosome rearrangements in human-Chinese hamster somatic cell hybrids. (6/181)

Analysis of human-Chinese hamster somatic cell hybrids with spontaneously derived chromosome structural changes has provided data for the regional and subregional localization of gene loci which have previously been assigned to human chromosomes 2, 12, and X. Correlation of the expression of human gene loci with the human chromosome complements present in somatic cell hybrids indicates that the cytoplasmic malate dehydrogenase (MDH1) locus is in the 2p23yields2pter region, and red cell acid phosphatase (AcP1) is at or adjacent to 2p23. The cytoplasmic isocitrate dehydrogenase (IDH1) locus is at or adjacent to 2q11, peptidase B (Pep B) is at or adjacent to 12q21, lactate dehydrogenase B (LDH B) is in the 12q21yiedls12pter region, glucose-6-phosphate dehydrogenase (G6PD) is in the Xq24yieldsXqter region, and the gene loci for phosphoglycerate kinase (PGK), alpha-galactosidase (alpha-gal), and hypoxanthine guanine phosphoribosyltransferase (GPRT) are in the Xp21yieldsXq24 region.  (+info)

Chromosome 3 duplication q21 leads to qter deletion p25 leads to pter syndrome in children of carriers of a pericentric inversion inv(3) (p25q21). (7/181)

Close phenotypic similarity between two cases carrying a rec(3) dup q,inv(3) (p25q21), 12 additional infants from the same inv (3)(p25q21) kindred who lived less than 1 year, and eight cases studied in other medical centers has led us to postulate the existence of a distinct chromosome 3 duplication-deletion syndrome. In the presence of trisomy for (3)q21 leads to qter and monosomy for (3)p25 leads to pter, the facial dysmorphy is unique: a distorted head shape due to irregular cranial sutures, thick low eyebrows, long eyelashes, persistent lanugo, distended veins on the scalp, hypertelorism, oblique palpebral fissures, a very short nose with a broad depressed bridge and anteverted nares, protruding maxilla, thin upper lip, micrognathia, low-set ears, and a short webbed neck. Port-wine stains, congenital glaucoma, cloudy corneas, cleft palate and harelip also occur frequently. Each infant has difficulty sucking and swallowing. Congenital anomalies of the cardiovascular system, of midgut rotation, and of the urogenital system are noted for the infants who died neonatally. Most frequent is a ventricular septal defect, followed by atrial septal defect, patent ductus arteriosus, patent foramen ovale, and coarctation of the aorta. Omphalocele, umbilical hernia, hyperplastic kidneys, polycystic kidneys, double ureter, hydro-ureter, hydronephrosis, and undescended testes often occur. The extremities are short in proportion to the length of the trunk. Clinodactyly, coxa valga, talipes, and spina bifida are frequently observed.  (+info)

Spatial distribution of chromosomes 1 and Y in human spermatozoa. (8/181)

The positions of chromosomes 1 and Y inside human spermatozoa were determined by differential staining techniques. In 85/100 cells the two chromosomes were in close contact and in association with a vacuole. This observation is in contrast to previous findings for chromosome No. 9 and the Y-chromosome whose positions do not appear to be correlated.  (+info)

Thus, several methods have been established to isolate or enrich white blood cells from patient blood samples for such analyses. One method of preparing an enriched white blood cell sample is through the selective lysis of red blood cells by hypotonic shock and restoration of osmolarity to maintain viability of target white blood cells. An inherent problem with this approach is the loss of target cells during ...

  • HOUSTON (March 17, 2005) If the human genome is indeed the "book of life," then the X-chromosome is all plot. (
  • Large numbers of medically related genes happen to fall on the X," said Dr. Steven Scherer, associate professor in the Baylor College of Medicine department of molecular and human genetics and director of mapping in the BCM Human Genome Sequencing Center. (
  • Although it contains a few important genes, it's almost like the appendix of the human genome. (
  • Several genome-wide screens have revealed susceptibility loci for IBD on 10 different chromosomes. (

  • One of the main deficiencies with the original chimpanzee genome sequence published in 20053 was that it was a draft sequence and only represented a 3.6-fold random coverage of the 21 chimpanzee autosomes, and a 1.8-fold redundancy of the X and Y sex chromosomes. (
  • In the case of a chimpanzee, an organism with a genome size of about 3 billion bases, a 3.6-fold coverage means that approximately 10.8 billion bases of DNA were sequenced (3.6 x 3.0). (
  • In the 2005 chimpanzee genome project and resulting Nature journal publication, the sequence contigs4 were not assembled and oriented based on a map of the chimpanzee genome, but rather on a map of the human genome. (
  • Given the fact that the chimpanzee genome is at least 10 percent larger5 overall than the human genome, this method of assembly was not only biased toward an evolutionary presupposition of human-chimp similarity, but was also inherently flawed. (

  • The potential of NPG di-2-ethylhexanoate (2,2-dimethylpropane-1,3-diyl 2-ethylhexanoate) to induce chromosomal damage in mammalian cells was evaluated in an in vitro mammalian chromosome aberration test performed according to GLP and OECD guideline 473, and EU method B.10 (Buskens, 2010). (
  • The genetic defect responsible for NF2 is a deletion of a portion of chromosome 22, the same chromosomal abnormality found in spontaneous spinal schwannomas, indicating that a single location causes Schwann cell tumor growth. (
  • 1 These chromosomal anomalies influence the molecular and cellular phenotype of the leukemic blasts and may be responsible for their malignant potential. (
  • The frequency of various chromosomal abnormalities is quite different in neonates (0.7%) as compared to abortuses (about 50%), since some aneuploidies are lethal in utero [3]. (
  • What is the chromosomal make-up of humans? (
  • We showed that HD-FISH probes can be used to localize individual genomic loci at sub-diffraction limit resolution, as well as to visualize chromosomal territories as discrete clouds of fluorescence spots-an approach which we named 'chromosome spotting' 2 , that allows to quantitatively assess various structural properties of chromosomes. (
  • At the same time, another group reported Oligopaint FISH 3 , a versatile method to produce DNA FISH oligo probes, named Oligopaints, which can be used to visualize entire chromosomes or sub-chromosomal regions. (

  • We recently provided evidence from immunofluorescence and electron microscopy studies that merotelic kinetochore orientation is a major mechanism for lagging chromosomes during mitosis in PtK1 cells. (
  • Hence, the activation of the mitotic checkpoint prevents the unbalanced distribution of chromosomes during mitosis and the production of aneuploid cells. (
  • While meiosis almost certainly evolved from mitosis, it has not one but four novel steps: the pairing of homologous chromosomes, the occurrence of extensive recombination between non-sister chromatids during pairing, the suppression of sister-chromatid separation during the first meiotic division, and the absence of chromosome replication during the second meiotic division. (
  • In the evolution of the eukaryotes, it can be assumed that the earliest eukaryotic species were single-cell haploid forms, possessing just a single set of chromosomes, and that they propagated by mitosis. (
  • Various proteins act to stabilize DNA in interphase, while additional proteins are required to condense the chromosomes over a thousandfold to form the compact chromosomes required for mitosis and cell division. (
  • During mitosis, DNA is packaged into chromosomes. (

  • Kinetochores of lagging chromosomes in anaphase human cells were found to be devoid of the mitotic checkpoint phosphoepitopes recognized by the 3F3/2 antibody, suggesting that they attached kinetochore microtubules prior to anaphase onset. (
  • Live cell imaging of H2B histone-GFP-transfected cells showed that cells with mono-oriented chromosomes never enter anaphase and that lagging chromosomes appear during anaphase after chromosome alignment occurs during metaphase. (
  • Thus, our results demonstrate that the mitotic checkpoint efficiently prevents the possible aneuploid burden due to mono-oriented chromosomes and that merotelic kinetochore orientation is a major limitation for accurate chromosome segregation and a potentially important mechanism of aneuploidy in human cells.
