The "cat eye" syndrome is uncommon and is characterized by iridal and choroidal coloboma(giving the appearance of cat eyes), anal atresia, and genitourinary and auricular anomalies. There is usually an associated chromosomal abnormality characterized by an extra, small, acrocentric fragment.  1, record 1, English, - cat%20eye%20syndrome

Recently, one of us (P.S.G.) reported three further cases of the cat eye syndrome and emphasized the significant variation in length of the abnormal chromosome and the mosaicism that frequently occurs.  1, record 1, English, - cat%20eye%20syndrome

Le syndrome de l'œil de chat évoque chez le porteur d'un petit chromosome surnuméraire un ensemble polymalformatif pouvant comporter cliniquement un colobone irien, une atrésie anale, des appendices ou fistules préauriculaires.  1, record 1, French, - syndrome%20des%20yeux%20de%20chat

Le syndrome de l'œil de chat se présente comme une affection dominante. Bien que l'on puisse invoquer une non-disjonction plus fréquente en rapport avec les masses d'hétérochromatine et leurs facilités d'échange, le chromosome surnuméraire se comporte en univalent et migre au hasard vers l'un des pôles cellulaires avec une probabilité de 50%.  1, record 1, French, - syndrome%20des%20yeux%20de%20chat

This type of translocation occurs between two acrocentric chromosomes with breaks on opposite sides of the centromere in each chromosome and rejoining of the long arms. This usually results in the loss of a minute centric fragment, the formation of a new metacentric chromosome, and a reduction in chromosome number in the balanced heterozygote.(GENCYT p. 237)  1, record 3, English, - Robertsonian%20fusion

(Abnormalities of the autosome-Group D) For instance, the short arms of a D group chromosomes can be deleted or duplicated without any obvious effect. "Robertsonian fusion" can take place between the long arms of two acrocentric chromosomes with loss of one centromere and short arms, resulting in normal and usually fertile heterozygotes who have no obvious loss of fitness and may have some selective advantage.(CLICYT p. 310)  1, record 3, English, - Robertsonian%20fusion

Une variété particulière de translocation réciproque s'opère entre les chromosomes acrocentriques, ceux qui appartiennent aux groupes D & G, par exemple entre un chromosome 13 et un chromosome 21. Elle est la conséquence d'une fusion centromérique et entraîne la perte des bras courts et des satellites qu'ils portent. Cette fusion centromérique est dite aussi robertsonienne.

Elles résultent de mutations particulières appelées "fusions centriques" réunissant deux chromosomes acrocentriques non homologues pour constituer un chromosome métacentrique. Désignées aussi sous le nom de "translocations robertsoniennes", elles ont pour effet de modifier le nombre des chromosomes, sans modifier celui des bras chromosomiques.  3, record 3, French, - fusion%20robertsonienne
