Williams-Beuren Syndrome

Introduction

Williams-Beuren Syndrome, more commonly known as William’s Syndrome, is a congenital anomaly caused by the deletion of 28 neighbouring genes on chromosome 7q11.23.[1] [2]

This multisystemic developmental genetic disorder implicates both pre-natal and post-natal physical, psychological, behavioural and medical defects, including diverse phenotypic characteristics such as:

  • distinctive facial deformities
  • a short stature
  • intellectual disabilities/mental retardation
  • cardiovascular abnormalities
  • infantile hypercalcemia
  • a unique personality and cognitive profile. [1] [3]

History of the disease

Timeline

Etiology

Diagnosis

Genetic Factors

Williams Syndrome, a genomic disorder, occurs due to a hemizygous deletion/nonallelic homologous recombination(NAHR) spanning 1.55 or 1.84Mb on chromosome 7q11.23 which encompasses 28 genes.[1] [3]

Other Abnormalities

There are a number of other abnormalities associated with Williams Syndrome including a hoarse voice, inguinal hernias and joint abnormalities. These abnormalities vary in severity between different individuals and elastin haploinsufficiency is responsible for a number of these abnormalities characteristic of Williams Syndrome.[4]
