William's Syndrome affects boys and girls from all walks of life

Welcome to our unique community!

Ever since 16961, Williams Syndrome has been touching the lives of families from all walks of life. Williams Syndrome has a 1 in 10000 chance of affecting someone, regardless of race, gender, or geography. Therefore, everyone with William's Syndrome is unique in their own way.

What is William's Syndrome?

William's Syndrome is a rare chromosomal abnormality that causes developmental and health issues. William's Syndrome does not shorten life expectancy, but its complications may. A genetic mutation causes William's Syndrome, with 26 genes on chromosome 7 being deleted.



So, what are the symptoms of William's Syndrome? Well, although everyone is affected differently, common symptoms include:

  • Delayed Speech (May become strong speech/auditory learning later)
  • Developmental Delays
  • Attention Deficit Disorder (ADD)
  • Clinodactyly (inner bend of the small finger)
  • Learning disorders
  • intellectual disability (mild to moderate)
  • sensitive hearing
  • high blood pressure
  • Various Heart Problems (Supravascular Aortic Stenosis, Supravascular Pulmonary Stenosis, Pulmonary Artery Stenosis)
  • Far-sightedness
  • Sunken Chest
  • Short (compared to rest of family)
  • Flattened nasal bridge
