Chromosome Breakage definition: A type of chromosomal aberration involving DNA BREAKS. Chromosome breakage can result in CHROMOSOMAL TRANSLOCATION; CHROMOSOME INVERSION; or SEQUENCE DELETION.
chromosome breakage definition: Regulated cleavage of the developing macronuclear genome at a limited number of chromosome breakage sites (CBS). The macronuclear destined segment (MDS) sequence adjacent to the CBS (or separated from it by a BES) receives a macronuclear telomere following chromosome breakage. [GOC:ns]
Nijmegen breakage syndrome (NBS) definition: A disorder, wherein unstable chromosomes have a tendency to break and become rearranged, characterized by microcephaly, stunted growth, subnormal mental development, cafe-au-lait spots, and immunodeficiency. The syndrome is named after the University of Nijmegen in the Netherlands.
Nijmegen Breakage Syndrome definition: A disorder, wherein unstable chromosomes have a tendency to break and become rearranged, characterized by microcephaly, stunted growth, subnormal mental development, cafe-au-lait spots, and immunodeficiency. The syndrome is named after the University of Nijmegen in the Netherlands. (JABL99)
Nijmegen breakage syndrome definition: characterized by short stature, progressive microcephaly with loss of cognitive skills, premature ovarian failure in females, recurrent sinopulmonary infections, and an increased risk for cancer, particularly lymphoma.
Nijmegen Breakage Syndrome definition: A chromosome instability syndrome resulting from a defective response to DNA double-strand breaks. In addition to characteristic FACIES and MICROCEPHALY, patients have a range of findings including RADIOSENSITIVITY, immunodeficiency, increased cancer risk, and growth retardation. Causative mutations occur in the NBS1 gene, located on human chromosome 8q21. NBS1 codes for nibrin, the key regulator protein of the R/M/N (RAD50/MRE11/NBS1) protein complex which senses and mediates cellular response to DNA DAMAGE caused by IONIZING RADIATION.
Nibrin definition: Encoded by human NBS1 Gene, ubiquitous expression of 754-amino acid 85 kD Nibrin occurs principally in testis, thymus, and spleen (sites of physiologic DNA double-strand breakage) and liver, lung, striated/smooth muscle, kidney, and gut (high proliferative activity). Nibrin contains a forkhead-associated domain and a C-terminal breast cancer domain. As part of the p95/NBS1/p200/p400/MRE11/RAD50 and the BASC complexes, NBS1 participates in DNA repair and meiotic recombination. Serine phosphorylation by ATM is linked to S-phase checkpoint activation. Nibrin/gamma-H2AX associate with V(D)J recombination sites in response to RAG1-mediated cleavage. Ig Class switch DNA recombination recruits NBS1/gamma-H2AX in G1. NBS1 mutations are associated with Nijmegen breakage syndrome, chromosomal instability, cancer, and cell cycle checkpoint defects. (from Swiss-Prot, OMIM, and NCI)
NBN wt Allele definition: Human NBN wild-type allele is located within 8q21 and is approximately 51 kb in length. This allele, which encodes nibrin protein, is involved in DNA double-strand break repair and DNA damage-induced checkpoint activation. Functional mutations in the NBN gene produce allelic variants that are involved in Nijmegen breakage syndrome.
Break definition: Issue associated with undesired damage or breakage of those materials used in device construction.
insurance against breakage definition: [1] Bruchschadenversicherung
breakage definition: Casse (débris produits des objets brisés, casse automobile).
