ANEUSOMIE RECOMBINAISON [2 records]

Record 1 2013-09-19

English

Subject field(s)
  • Genetics
DEF

An inversion that is entirely within one arm of a chromosome, does not include the centromere.

CONT

When the two breaks occur within the same arm, the break point more proximal to the centromere is specified first; for example, inv (2) (p 13 p 23) defines a paracentric inversion in the short arm of chromosome no 2 with break points in bands 2 p 13 and 2 p 23.

French

Domaine(s)
  • Génétique
DEF

Inversion qui touche un bras chromosomique au-delà du centromère.

CONT

Une aneusomie de recombinaison est le résultat d’un réarrangement lors de la méiose, à la suite d’un [crossing-over], dans un chromosome parental équilibré mais déjà porteur d’une malfaçon par inversion péricentrique, paracentrique ou insertion.

Spanish

Campo(s) temático(s)
  • Genética
DEF

Reajuste cromosómico que se produce cuando un segmento cromosómico, que excluye al centrómero, cambia de orientación.

Record 2 1985-11-04

English

Subject field(s)
  • Genetics
DEF

"Aneusomie" resulting from exchange mechanism and appearing during meiosis in subjects with a balanced rehandling.

CONT

Great care should be exercised before associating a chromosome abnormality in a proband with a phenotypic change when a phenotypically normal sib or parent carries what is apparently the same chromosome abnormality. The concept of "aneusomie de recombinaison" has been suggested to account for this finding (Lejeune et Berger, 1965; De Grouchy et al., 1965, 1966)

OBS

It seems that the term "aneusomy" is rarely used in English.

French

Domaine(s)
  • Génétique
DEF

Aneusomie résultant des mécanismes d’échanges survenant lors de la méiose chez un sujet porteur d’un remaniement équilibré. (FLAME)

CONT

Enfin, il est des cas où un enfant malformé a un caryotype anormal apparemment identique à celui d’un de ses parents phénotypiquement normal. Lejeune et Berger ont proposé une ingénieuse explication pour expliquer ces faits, celle de l'aneusomie de recombinaison due à l'échange normal de chromatides survenant lors de la méiose chez un sujet porteur d’un remaniement chromosomique.(PATMED p. 70)
