Topology of constitutional reciprocal translocations in metaphase

Annales de Génétique, 2004
We studied in 39 carriers of 26 reciprocal translocations (including five de novo and seven of indeterminate occurrence) the metaphase localization of the derivative chromosomes, their normal non-homologous counterparts (here called A and B), and two control pairs (C and D). In eight familial translocations, we analysed two to five carriers.

Segregation analysis in reciprocal translocation carriers

American Journal of Medical Genetics, 1984
AbstractSegregation analysis of the offspring of balanced translocation carriers was performed on 327 pedigrees collated from published sources and personal communications. Correction was made for bias of ascertainment. Translocations studied involved chromosome arms 1p, 4q, 6p, 6q, 7p, 8p, 10p, 10q, 11q, 14q, 16q, and 17p.

Double reciprocal translocation heterozygosity in a bull

Veterinary Record, 1982
A double reciprocal translocation has been found in a morphologically normal but infertile bull (Bos taurus), using trypsin-Giemsa banding. The karyotype of the bull can be written as: 60,XY,t(2q-;20q+),t(8q-;27q+). Cytophotometric studies supported the findings in the karyograms and identified the breakpoints in the chromosomes involved.

Translocation (1;19)(q21;q13.3) is a recurrent reciprocal translocation in meningioma

Cancer Genetics and Cytogenetics, 2002
Benign meningiomas are characterized by a normal karyotype or loss of all or part of chromosome 22. Histologically higher grade tumors are typically characterized by a pattern of increasing chromosome loss and instability. This characteristic pattern of unbalanced chromosome aberrations is punctuated in the literature by several intriguing reports of a

A de novo translocation in a family with a balanced reciprocal chromosomal translocation

Clinical Genetics, 1986
A carrier of a reciprocal translocation between chromosomes 10 and 18 had a child with a reciprocal translocation involving different segments of the same chromosomes. The categories of possible meiotic errors in carriers of balanced rearrangements must, therefore, be expanded to include new reciprocal translocations.

Autosomal reciprocal translocations and 13/14 translocations: A population study

Clinical Genetics, 1976
Fifteen children with autosomal reciprocal translocations were found in an incidence study of chromosome aberrations among 11,148 consecutively liveborn children in a Danish Maternity Hospital (1.34 per 1,000).The segregation rate of the balanced forms was 60 % and that of unbalanced forms 4 %; the frequency of familial cases was 73 %.

Autosomal Reciprocal Translocations

2011
Abstract RECIPROCAL TRANSLOCATIONS ARE COMMON, and every counselor can expect to see translocation families. The usual form is the simple, or two-way, reciprocal translocation: only two chromosomes, usually autosomes, are involved, with one breakpoint in each. It is this category we consider in this chapter.

Sorting Genomes by Reciprocal Translocations, Insertions, and Deletions

IEEE/ACM Transactions on Computational Biology and Bioinformatics, 2010
The problem of sorting by reciprocal translocations (abbreviated as SBT) arises from the field of comparative genomics, which is to find a shortest sequence of reciprocal translocations that transforms one genome Pi into another genome Gamma, with the restriction that Pi and Gamma contain the same genes.

Reciprocal translocation with adaptive segment length

Proceedings of the 2002 Congress on Evolutionary Computation. CEC'02 (Cat. No.02TH8600), 2003
A novel artificial crossover operator based on reciprocal translocation of chromosomal segments is introduced. Positions and lengths of genome segments are determined at random. However, the segment size limits are adaptively changed based on the improvement of average fitness value over generations.

Reciprocal translocations: a trap for cytogenetists?

Human Genetics, 2005
We report four cases of subjects with phenotypic abnormalities and mental retardation associated with apparently balanced translocations, two inherited and two de novo, which showed, by molecular analysis, a hidden complexity. All the cases have been analyzed with different molecular techniques, including array-CGH, and in two of them the translocation
