What are the symptoms of cat cry syndrome?
The clinical symptoms of cri du chat syndrome usually include a high-pitched cat-like cry, mental retardation, delayed development, distinctive facial features, small head size (microcephaly), widely-spaced eyes (hypertelorism), low birth weight and weak muscle tone (hypotonia) in infancy.
How rare is Cri du Chat?
Cri du chat syndrome is a rare genetic disorder caused by a missing section on a particular chromosome known as Chromosome 5. Sometimes, material from another chromosome is missing as well. Around one in every 50,000 or so babies is diagnosed with this disorder.
How does Cri du Chat syndrome affect a person?
Moderate to severe intellectual disability is present in most cases. Speech development is especially delayed in children with cri du chat syndrome. Affected children usually understand speech better than they can communicate. Some children may display hyperactivity or self-abusive behaviors.
Why would someone get tested for Cri du Chat Syndrome?
Researchers believe that the loss of a specific gene, CTNND2, is associated with severe intellectual disability in some people with this condition. They are working to determine how the loss of other genes in this region contributes to the characteristic features of cri-du-chat syndrome.
What are the signs and symptoms of Williams syndrome?
What are the symptoms of Williams syndrome?
- specific facial features like a wide mouth, small upturned nose, widely spaced teeth, and full lips.

- attention deficit hyperactivity disorder (ADHD)
- learning disorders.
- inward bend of pinky finger.
- specific phobias.
- short stature.
- speech delays.
How long can a person live with Williams syndrome?
Some people with Williams syndrome may have a reduced life expectancy due to complications of the disease (such as cardiovascular involvement). No studies specifically exist on life expectancy, although individuals have been reported to live into their 60s.

Is Williams syndrome a form of autism?
Autism spectrum disorders (ASD) and Williams syndrome (WS) both are neurodevelopmental disorders, each with a unique social phenotypic pattern.
Why is Williams syndrome called the Happy syndrome?
Scientists realized it was related to the levels of oxytocin. They knew that oxytocin is involved in social/intimacy behaviors, like mother-child bonding or romantic encounters. And they found that people with Williams syndrome have a lot more oxytocin than everybody else, and that it fluctuates wildly in the brain.
Can Williams syndrome be cured?
There is currently no cure for Williams syndrome. Treatment aims to support the person and manage associated symptoms. There may be many physical, developmental, intellectual and social problems present in Williams syndrome, which may require a team of health professionals.
What are some interesting facts about Williams syndrome?
Williams Syndrome (WS) is a rare genetic disorder characterized by mild to moderate delays in cognitive development or learning difficulties, a distinctive facial appearance, and a unique personality that combines over-friendliness and high levels of empathy with anxiety.
What's the opposite of autism?
Chris has Williams Syndrome (WS), a rare genetic disorder affecting around one in 18,000 people in Britain. It has often been dubbed the 'opposite of autism'. People with WS are empathetic, social, friendly and endearing but they tend to have a low IQ, making tasks such as counting money difficult.
Can you look normal and have Down syndrome?
Some of the children with Mosaic Down syndrome that we know do not actually look as if they have Down syndrome - the usual physical features are not obvious. This raises some important and difficult social issues and identity issues for both parents and children, which parents have discussed with us.
What is the rarest trisomy?
Trisomy 17 mosaicism is one of the rarest trisomies in humans. It is often incorrectly called trisomy 17 (also referred to as full trisomy 17), which is when three copies of chromosome 17 are present in all cells of the body. Full trisomy 17 has never been reported in a living individual in the medical literature.
Is trisomy 9 Down syndrome?
Similar to trisomy 21 (also known as Down syndrome), trisomy 9 occurs when there are three copies (as opposed to the usual two) of chromosome 9 present in a fetus's cells. Trisomy 9 is rarer than trisomy 21 and has more severe manifestations. It also has a much lower survival rate.
Is Down syndrome hereditary?
Most of the time, Down syndrome isn't inherited. It's caused by a mistake in cell division during early development of the fetus. Translocation Down syndrome can be passed from parent to child.
