Cat eye syndrome generally affects the eyes with 3 or 4 extra chromosomes in chromosome 22 causing missing ocular tissue causing the cat eye appearance.
Possible effects of cat eye syndrome can include unusually shaped ears, downward slanting palpebral fissures, congenital heart defects, and skeletal abnormalities.
In chromosome 22 there are three or four extra chromosomes rather than just two normally.
Cat eye syndrome is only inherited through parental genetics.
It is sex-linked from chromosome 22 and is recessive not dominant.
Genetic testing or physical symptoms can diagnose cat eye syndrome.
It is not more common in a certain group of people and only 1 - 50,000 to 1 - 150,000 people have cat eye syndrome.
Cat eye syndrome has many syndromes and effects that are associated with it.
