Translocation

 

(1) In genetics, a type of chromosomal restructuring (mutation) involving an interchange between parts of chromosomes; it often leads to a decrease in the fertility of animals and plants.

(2) The transference of substances in and out of a cell through a biological membrane by means of a biochemical transport system.

(3) In plants, the movement of water through the xylem and of nutrients through the phloem.

Translocation is an indispensable method in the conservation of giant pandas, especially for small populations (Zhang & Wei 2006).
Chromosomal analysis of the wife showed 46, XX normal female karyotype, whereas the husband's karyotype showed 46,XY,13p+ (Figure 1A), which was later refined to a de novo terminal translocation involving chromosomes 11 and 13.
Carriers of t(11;22) are phenotypically normal, which could be the reason it is rarely diagnosed until they present with recurrent miscarriages or give birth to a child with the unbalanced translocation. When a case of ES is diagnosed, it is important to perform a genotypic analysis in both of the parents to identify the carrier of the translocation.
The pre-translocation activities must include scientific and technical inputs to inform planning, careful consideration of the justification and objectives of the proposed translocation, feasibility assessments to determine whether the translocation should proceed as planned.
If there is no active board, the guidelines say, the final decision will be made by the Cabinet secretary.Once the exercise is approved, a multidisciplinary coordination committee is expected to come in and oversee the translocation.

The team envisions the prospect of further explorations in this regard, by identifying these missing intermediaries to clarify how ATP hydrolytic events and nucleotide exchange are coordinated with each other, and allosterically linked to substrate translocation.
Patients were enrolled into one of three cohorts Cohort A (FGFR2 translocations), Cohort B (other FGF/FGFR genetic alterations [GA]) or Cohort C (no FGF/FGFR GAs).

The translocation is observed in the conventional karyotype, and the number of chromosomes can be reduced if the short arm of the chromosome produced by the translocation is lost in cell division (7,8).
