Who is affected by cat eye syndrome?
Cat eye syndrome affects both males and females and is estimated to occur in one in 50,000 to one in 150,000 individuals. 1 If you have CES, you are most likely the only one in your family to have the condition since it's a chromosomal abnormality as opposed to a gene. via
Does cat eye syndrome affect life expectancy?
Outlook for people with cat eye syndrome
Some people with CES will have severe malformations in early infancy, which can lead to a much shorter life expectancy. However, for most people CES, life expectancy usually isn't reduced. via
What is the current status of research for cat eye syndrome?
However, the syndrome is very rare, and currently there are no accurate estimates of the incidence of CES in the population. Schinzel et al (1981) estimated an incidence of approximately one in 50,000 to one in 150,000 individuals in Northeastern Switzerland. via
Is cat eye syndrome dominant or recessive?
Cat eye syndrome can be inherited in one of two ways. Either the duplication on chromosome 22 is passed down from parent to child in what is called autosomal dominant inheritance or the duplication occurs only in the affected person this is called a de novo mutation, meaning it occurred by random chance. via
Can humans get cat eyes?
It's caused by a problem with a chromosome, so people are born with it. It gets its name because one of the most common symptoms is that the eyes look similar to a cat's. This is because there's a hole in the iris (the colored part of your eye). Only between 1 in 50,000 and 1 in 150,000 people in the world have it. via
What causes cat eye?
Cat eye syndrome is most often caused by a chromosome abnormality called an inverted duplicated 22. In people with this condition, each cell has at least one small extra (duplicate) chromosome made up of genetic material from chromosome 22. via
What is cat's cry syndrome?
Collapse Section. Cri-du-chat (cat's cry) syndrome, also known as 5p- (5p minus) syndrome, is a chromosomal condition that results when a piece of chromosome 5 is missing . Infants with this condition often have a high-pitched cry that sounds like that of a cat. via

Who discovered cat eye?
The first report on the association of coloboma and anal atresia with a small extra chromosome came from Schmid in Zurich and Fraccaro in Pavia (Schachenmann et al., 1965). These authors proposed the term cat eye syndrome, in analogy with the cat cry or cri-du-chat syndrome (123450). via
Why do cat eyes change shape?
Depending on the light, the shape of a domestic cat's pupil changes from vertical slit to alluring almond to almost fully round. Like most predators, a cat's eyes face forward. Their brain compares the slightly different images relayed from the left and right eye to help estimate distance – a process called stereopsis. via
What is Jacobsen syndrome?
Jacobsen syndrome is a condition caused by a loss of genetic material from chromosome 11. Because this deletion occurs at the end (terminus) of the long (q) arm of chromosome 11, Jacobsen syndrome is also known as 11q terminal deletion disorder. via
What are cat eyes called?
In cats, the most sensitive area of the retina is called the area centralis. The eyes of a cat are protected not only by the same types of eyelids that people have, but also by the nictitating membrane, which is sometimes called the third eyelid. via
