How is cat eye syndrome diagnosed?

The diagnosis of CES is based on the presence of extra chromosomal material derived from chromosome 22q11. (see “Causes” above). It is possible that a diagnosis of CES may be suspected before birth (prenatally) based upon specialized tests, such as ultrasound, amniocentesis, and/or chorionic villus sampling (CVS).

How does Cat eye syndrome start?

Can someone with Down syndrome have normal intelligence?

scores for people with Down syndrome vary, with the average cognitive delays being mild to moderate, not severe. In fact, normal intelligence is possible. If a person with Down syndrome has difficulty with hearing, it can be misinterpreted as a problem with understanding.

Several conditions may cause decreased muscle tone, such as Down syndrome, DiGeorge syndrome, and cerebral palsy.
