Interaction of acrocentric chromosome involved in translocation and sex of the carrier influences the proportion of alternate segregation in autosomal reciprocal translocations

Human Reproduction, 2018
STUDY QUESTION Are meiotic segregation patterns of reciprocal translocations affected by the combined effect of chromosome type and carrier's sex? SUMMARY ANSWER Interaction of an acrocentric chromosome (Acr-ch) involved in the translocation and sex of

Reciprocal or nonreciprocal human chromosome translocations?

Human Genetics, 1977
Two carriers of a balanced translocation, one paternal t(9q-;13p+) and one maternal t(3q-;15p+), were studied cytogenetically with selective silver staining to localize more precisely the break points on the short arms of the two acrocentric chromosomes involved.

Reciprocal Translocations in Pisum

Nature, 1950
SOME years ago I published an analysis of structurally changed types of Pisum sativum based on cytological observations1. One of these, structural type four which had arisen in the variety Extra Rapid, was reported as having chromosomes 3 and 5 interchanged, according to my notation.

Autosomal Reciprocal Translocations

2018
This chapter reviews in detail the question of carriers of autosomal reciprocal translocations and the genetic risks implied for potential offspring of theirs. Examples are offered of the various possibilities due to malsegregation in gametes of theirs: adjacent-1, adjacent-2, 3:1, and the (very rare) 4:0 malsegregation.

Partners with reciprocal translocations: genetic counseling for the ‘double translocation’

Clinical Genetics, 1998
SV at age 2 years presented with multiple congenital anomalies including an absent left kidney, anal stenosis, vertebral abnormalities, partial sacral agenesis, microcephaly, dysmorphic facial features, growth deficiency, and developmental delay. She was found to have a complex chromosomal rearrangement derived from balanced translocations in each ...

Lack of reciprocal translocations in carcinomas

Cancer Genetics and Cytogenetics, 1986
Among the varied structural chromosomal aberrations present in the common forms of carcinoma, reciprocal translocations generally appear to be lacking. Although the breakpoints may be variable, the chromosomal changes nevertheless commonly result in the loss or gain of particular chromosomal segments. The possible implications of these observations are

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.

RECIPROCAL TRANSLOCATIONS IN SORGHUM VULGARE

Canadian Journal of Genetics and Cytology, 1963
Endrizzi and hilorgan ( 1955) reported the occurrence of reciprocal translocations in Sorghz~77jl m ~ l g a r e but did not examine pachynema configurations. The present study deals with cytological observations at prophase of meiosis, including pachynema, of three reciprocal translocations obtained by Haensel (1960) after gamma irradiation of the ...

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.

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.
