Background : Williams syndrome WS is a genetically based disorder caused by deletion of elastin and contiguous genes on chromosome 7q This syndrome is characterized by multiorganic involvement with dysmorphic facial features and a distinctive cognitive profile. It is an interesting model for elucidation of relationships between brain, cognition and genes. Patients have a visual-spatial cognition impaired with relative strengths in social and language abilities.
