Copy of What is Williams Syndrome?

Williams syndrome (WS) is a genetic condition that is present at birth and can affect anyone.  It is characterized by medical problems, including cardiovascular disease, developmental delays, and learning disabilities.  These often occur side by side with striking verbal abilities, highly social personalities and an affinity for music.


WS affects 1 in 10,000 people worldwide – an estimated 20,000 to 30,000 people in the United States. It is known to occur equally in both males and females and in every culture.

Unlike disorders that can make connecting with your child difficult, children with Williams syndrome tend to be social, friendly and endearing.  Parents often say the joy and perspective a child with WS brings into their lives has been unimaginable.

But there are major struggles as well.  Many babies have life-threatening cardiovascular problems. Children with WS need costly and ongoing medical care and early interventions (such as speech or occupational therapy) that may not be covered by insurance or state funding.  As they grow, they struggle with things like spatial relations, numbers, and abstract reasoning, which can make daily tasks a challenge. As adults, most people with Williams syndrome will need supportive housing to live to their fullest potential.  Many adults with WS contribute to their communities as volunteers or paid employees; often working at assisted living homes for senior citizens, hospitals and libraries, or as store greeters or veterinary aides.   

Just as important are opportunities for social interaction. As people with Williams syndrome mature – beyond the structure of school and family activities – they often experience intense isolation which can lead to depression.  They are extremely sociable and experience the normal need to connect with others; however people with Williams syndrome often don’t process nuanced social cues and this makes it difficult to form lasting relationships.




Most young children with Williams syndrome are described as having similar facial features. These features include a small upturned nose, long philtrum (upper lip length), wide mouth, full lips, small chin, and puffiness around the eyes. Blue and green-eyed children with Williams syndrome can have a prominent "starburst" or white lacy pattern on their iris. Facial features become more apparent with age.



The majority of individuals with Williams syndrome have some type of heart or blood vessel problem. Typically, there is narrowing in the aorta producing supravalvular aortic stenosis (SVAS), or narrowing in the pulmonary arteries. There is a broad range in the degree of narrowing, ranging from trivial to severe (requiring surgical correction of the defect). Since there is an increased risk for development of blood vessel narrowing or high blood pressure over time, periodic monitoring of cardiac status is necessary.



Some young children with Williams syndrome have elevations in their blood calcium level. The true frequency and cause of this problem is unknown. When hypercalcemia is present, it can cause extreme irritability or "colic-like" symptoms. Occasionally, dietary or medical treatment is needed. In most cases, the problem resolves on its own during childhood, but lifelong abnormality in calcium or Vitamin D metabolism may exist and should be monitored.



Most children with Williams syndrome have a slightly lower birth-weight than their brothers or sisters. Slow weight gain, especially during the first several years of life, is also a common problem and many children are diagnosed as "failure to thrive". Adult stature is smaller than average.



Many infants and young children have feeding problems. These problems have been linked to low muscle tone, severe gag reflex, poor suck/swallow, tactile defensiveness etc. Feeding difficulties tend to resolve as the children get older.



Many infants with Williams syndrome have an extended period of colic or irritability. This typically lasts from 4 to 10 months of age, then resolves. Abnormal sleep patterns with delayed acquisition of sleeping through the night may be associated with the colic.  Extreme irritability may also be caused by hypercalcemia in some children with WS.



Slightly small, widely spaced teeth are common in children with Williams syndrome. They also may have a variety of abnormalities of occlusion (bite), tooth shape or appearance. Most of these dental changes are readily amenable to orthodontic correction.



There is a slightly increased frequency of problems with kidney structure and/or function.



Inguinal (groin) and umbilical hernias are more common in Williams syndrome than in the general population.



Children with Williams syndrome often have more sensitive hearing than other children; certain frequencies or noise levels can be painful and/or startling to the individual. This condition often improves with age.



Young children with Williams syndrome often have low muscle tone and joint laxity. As the children get older, joint stiffness (contractures) may develop. Physical therapy is very helpful in improving muscle tone, strength and joint range of motion.



Individuals with Williams syndrome have a very endearing personality. They have a unique strength in their expressive language skills, and are extremely polite. They are typically unafraid of strangers and show a greater interest in contact with adults than with their peers.



Most people with Williams syndrome will have mild to severe learning disabilities and cognitive challenges. Young children with Williams syndrome often experience developmental delays.  Milestones such as walking, talking and toilet training are often achieved somewhat later than is considered normal. Distractibility is a common problem in mid-childhood, which can improve as the children get older.

Older children and adults with Williams syndrome often demonstrate intellectual "strengths and weaknesses." There are some intellectual areas (such as speech, long term memory, and social skills) in which performance is quite strong, while other intellectual areas (such as fine motor and spatial relations) show significant weakness.

Not all Williams Syndrome individuals are the same!  (gasp!)  Just as no other human being or individual on Earth is the same!  


We truly are all unique; and are all different - and that's what makes life exciting, in my opinion.  If you're still reading at this point, and are ready to become a quick expert on Williams Syndrome, here's a brief summary so you can help us educate the World. Because, based on the numbers you've read about - our small little army could use your help educating; i.e. "spreading awareness."



(in a nutshell)

(For some individuals - not all.  What we notice in Ava, has an asterisk*)


  • Mild to Severe Cardiac Disorders
  • Difficulty with Anesthesia (& reason for trying to fund money for medical research)
  • Excellent Long Term Memory
  • Low Birth Weight
  • Musculoskeletal Issues
  • Low Muscle Tone*
  • Excellent Memory of Faces
  • Developmental Delays*
  • Very Endearing Personality*
  • Extremely Friendly*
  • Learning Disabilities*
  • Immensely Compassionate*
  • Feeding Difficulties
  • Very Talkative*
  • Excellent Vocabulary
  • Perceptual/Spatial Difficulties*
  • Strong passion for Music*
  • Small Stature*
  • Small, Widely Spaced Teeth*
  • Starburst Pattern in Blue Eyes*
  • Poor Fine Motor Skills
  • Extreme Colic during Infancy*
  • Hypercalcemia (High Blood Calcium Issues)
  • Kidney Abnormalities
  • Hernias
  • Hyperacusis (Sensitive Hearing)
  • A.D.D.*


Commonalities amongst ALL children with Williams Syndrome:


  • Missing Genes on one copy of Chromosome 7 - "Elastin" is the marker Gene
  • Unique.  Individuals with Williams Syndrome are born in ALL cultures - all around the WORLD!  (How's that for proving that we humans are truly "more alike than different?!"
  • The best human you will ever encounter in your lifetime - make it a point to meet someone with Williams Syndrome!  The world actually needs more individuals like those who have Williams Syndrome.


Thank you from the bottom of my heart for reading all of this!  "Spreading awareness" is a phrase that you hear a lot, but I sometimes wonder if anyone is listening?  Or if people actually know what "spreading awareness" means.  I know I fully didn't.  And because of that, it's my mission to not only "spread awareness" (i.e. educate), but to also help financially with the much needed therapies our Williams Syndrome population need (and other special needs children need) - to simply live a good life.  No matter a person's "label", we are ALL individuals, and should always be given a chance - a chance to become the best version of ourselves as possible!


To contribute to the Williams Syndrome Association'smission to fund a medical research on cardiovascular health in individuals with Williams Syndrome, CLICK HERE. (You can even mention Ava Connor's name as your inspiration for the donation). Why is your donation for this so important?  Briefly; of the 26-28 genes those with Williams Syndrome lack; only one gene's responsibility is understood so far - it is called the "Elastin Gene".  The Elastin Gene was discovered in 1993, and to put it simply, it is basically thought to be the "muscle" of your cells. It's absence in individuals with Williams Syndrome, makes performing commonly needed open heart surgeries, VERY hard to perform.  The missing Elastin Gene which naturally relaxes their bodies, coupled with the use of (even more relaxing) anesthesia, puts these individuals at a strong disadvantage during surgery; of any type in fact.  So much so, that every time they go under anesthesia - it is life threatening and has to be done at a major medical facility.  So with our proposed study, our goal would be for the medical community to better understand the makeup of their bodies more, so they could better figure out how to operate on them...the critical operations needed to save their lives.
