Williams syndrome is a developmental disorder that affects many parts of the body. This condition is characterized by mild to moderate intellectual disability or learning problems, unique personality characteristics, distinctive facial features, and heart and blood vessel (cardiovascular) problems.
Williams (WS) and Down (DS) syndromes are characterised by roughly opposing ability profiles. Relative verbal strengths and visuospatial difficulties have been reported in those with WS, while expressive language difficulties have been observed in individuals with DS.
Abstract. Williams syndrome is a neurodevelopmental disorder characterized by hypersociability and unique neurocognitive abnormalities. One of the characteristics of Williams syndrome is an inappropriate increase in social behavior. People with the syndrome may be overly friendly, even to strangers.
Individuals with WS typically demonstrate an overly friendly, affectionate, engaging, and socially disinhibited personality [6, 12].
There are three types of Down syndrome: trisomy 21 (nondisjunction), translocation and mosaicism. Trisomy 21 (nondisjunction) accounts for 95% of known cases of Down syndrome.
Most individuals with Down syndrome have mild (IQ: 50–69) or moderate (IQ: 35–50) intellectual disability with some cases having severe (IQ: 20–35) difficulties. Those with mosaic Down syndrome typically have IQ scores 10–30 points higher than that.
People of all ages with Down syndrome can and do enjoy a variety of relationships with family members, friends, acquaintances, community members, and even sweethearts and spouses.
Williams syndrome (WS) is a rare genetic disorder that occurs in about 1 in 8,000 births. It is associated with developmental delays and medical problems affecting multiple parts of the body. Features of Williams syndrome include: Characteristic facial features that have been described as pixie-like.
What is Kabuki syndrome? Kabuki syndrome is a rare congenital disorder, meaning that a child is born with the condition. Children with Kabuki syndrome usually have distinctive facial features, mild to moderate mental impairment and growth problems.
Overview. Williams syndrome is a rare genetic condition that causes facial characteristics including epicanthal folds at the eyes, large ears, an upturned nose, full cheeks, a wide mouth, a small jaw and small teeth.
Children with Williams syndrome typically have a personality that is friendly, outgoing, and/or talkative. The appropriate use of language and vocabulary range may be unusually enhanced in some children with this disorder.
Only child syndrome is a theory referring to certain characteristics that people may associate with being an only child. However, there is no reliable evidence that being an only child significantly affects personality or behavior. Therefore, current research states that only child syndrome is not real.
A child with DSED has no hesitation in talking with strangers or seeking physical comfort, such as hugs, from a person who isn't their parent or caregiver. They may even wander off with a person they just met.
Up Syndrome is a groundbreaking initiative from Colombia aiming to instill a change in the way people with - what was previously called - Down Syndrome are viewed. It was given its original name from the British doctor John Langdon Down, the first person to describe this genetic alteration.
Autism and Williams syndrome are genetically based neurodevelopmental disorders that present strikingly different social phenotypes. Autism involves fundamental impairments in social reciprocity and communication, whereas people with Williams syndrome are highly sociable and engaging.
In some ways Williams syndrome is the opposite of autism. For example, people with Williams syndrome love to talk and tell stories, whereas those with autism usually have language delay and little imagination. Many people with Williams syndrome draw disjointed pictures, some with autism draw pictures in perfect detail.
Children with Kabuki syndrome have a distinctive facial appearance, which includes abnormally long openings between the eyelids (palpebral fissures), lower eyelids that are turned outward (everted), prominent eyelashes, arched eyebrows, a broad nose with a flattened or depressed tip, and large, misshaped ears.
Summary. Russell-Silver syndrome (RSS) is a rare disorder characterized by intrauterine growth restriction (IUGR), poor growth after birth, a relatively large head size, a triangular facial appearance, a prominent forehead (looking from the side of the face), body asymmetry and significant feeding difficulties.
What causes Robinow syndrome? A genetic mutation causes Robinow syndrome. In autosomal recessive Robinow syndrome, the mutation occurs in the ROR2 gene. Scientists believe the gene is responsible for making a protein involved in the formation of the skeleton, heart and genitals.
What is Apert Syndrome? Apert syndrome, also called acrocephalosyndactyly, is a genetic syndrome characterized by anomalies of the skull, face and limbs. Gene mutations are responsible for causing the early fusion of the skull, hand and feet bones.
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 a couple with Down syndrome have children? It is often difficult for a couple with Down syndrome to conceive a child due to low fertility in the male and lack of ovulation in the female and the likelihood of entering menopause early.
Yes. A woman with Down's syndrome can have children. If her partner does not have Down's syndrome, the theoretical chance of the child having Down's syndrome is 50%. There have been only a few reports of men with Down's syndrome fathering children.
Many pregnancies in women with Down syndrome produce children both with normal and with trisomy 21, whereas males are infertile. However, Down syndrome males are not always infertile and this is not global. Here we reported a 36-year-old man with proved nonmosaic trisomy 21 fathered two normal boys.
