Area of Science:

  • Genetics and Rare Diseases
  • Pediatrics and Adult Medicine
  • Cardiology

Background:

  • Limited research exists on the long-term health outcomes and daily lives of adults with Williams syndrome (WS).
  • This study addresses the gap by examining a cohort of ten adult patients diagnosed with WS.

Observation:

  • Patients presented with a wide spectrum of clinical severity, from complex medical histories to generally good health.
  • Frequent observations included cardiovascular anomalies (e.g., supravalvular aortic stenosis, mitral valve prolapse) and hypertension.
  • Characteristic facial features such as stellate irides, prominent cheeks, full lips, and micrognathia were noted in all patients.

Findings:

  • All ten adult patients exhibited intellectual disability, with verbal skills generally surpassing motor skills.

  • Despite challenges, patients led active lives, participating in sports and some in supervised employment.
  • Most patients lived with parents or in group homes, highlighting limitations in independent living due to cognitive and adaptive factors.

    • Implications:

    • Understanding the adult phenotype of Williams syndrome is crucial for comprehensive care planning.
    • The findings underscore the need for ongoing cardiovascular monitoring and tailored support for daily living.
    • Further research into adaptive strategies and long-term care models for adults with WS is warranted.
