In genetics, chromosome translocation is a phenomenon that results in unusual rearrangement of chromosomes. This includes balanced and unbalanced translocation, with two main types: reciprocal-, and Robertsonian translocation. Reciprocal translocation is a chromosome abnormality caused by … See more Reciprocal translocations are usually an exchange of material between non-homologous chromosomes and occur in about 1 in 491 live births. Such translocations are usually harmless, as they do not result in … See more Robertsonian translocation is a type of translocation caused by breaks at or near the centromeres of two acrocentric chromosomes. The … See more Denotation The International System for Human Cytogenetic Nomenclature (ISCN) is used to denote a translocation between chromosomes. … See more The initiating event in the formation of a translocation is generally a double-strand break in chromosomal DNA. A type of DNA repair that has … See more Nonreciprocal translocation involves the one-way transfer of genes from one chromosome to another nonhomologous chromosome. See more Some human diseases caused by translocations are: • Cancer: Several forms of cancer are caused by acquired … See more In 1938, Karl Sax, at the Harvard University Biological Laboratories, published a paper entitled "Chromosome Aberrations Induced by X-rays", … See more WebA chromosomal rearrangement means that pieces of chromosomes are missing, duplicated (there are extra copies), or moved around. The effects vary. They depend on which chromosome pieces are involved and how they are rearranged. Some have no effect, some are incompatible with life, and others are somewhere between.

Most cancers, if not all, could cause chromosome abnormalities, with either the formation of hybrid genes and fusion proteins, deregulation of genes and overexpression of proteins, or loss of tumor suppressor genes (see the "Mitelman Database" and the Atlas of Genetics and Cytogenetics in Oncology and Haematology, ). Furthermore, certain consistent chromosomal abnormalities can turn normal cells into a leukemic cell such as the translocation of a gene, res… WebApr 10, 2009 · Although associated symptoms and findings may vary, the disorder is often associated with delayed growth before and after birth (prenatal and postnatal growth retardation); varying degrees of mental retardation; distinctive abnormalities of the skull and facial (craniofacial) region; and/or other features.
