    1. High blood calcium levels
    2. Colic like symptoms due to metabolic problems of VitD in the body
  4. Feeding problems
    1. This is due to poor muscle tone, severe gag reflex, poor swallow and tactile defensiveness
  5. Colic during infancy
    1. Extreme irritability or extended colic is typical

  9. Developmental Delays
  10. Learning disability

Williams Syndrome Cause

WS is caused by the deletion of genetic material from a specific region of chromosome 7. The deleted portion includes more than 25 genes, and researchers think that a loss of several of these genes probably contributes to the characteristic features of this disorder. Occurrence is 1 in 7500 to 20 000 children.

Intervention

Since it’s a condition affecting multiple organs, there has to be constant support from many specialists throughout their lives. Pediatricians, Cardiovascular specialists, Surgeons, Speech language Therapists, Occupational Therapists and Special Educators all work collectively for the rehab of children born with Williams Syndrome.
