Virtually all souls by having Williams syndrome come missing astir Twenty-one genes on chromosome 7, including the factor for the production of elastin.

A second result of Williams syndrome is want of depth perception and inability to visualize how different arethe assmble into big objects (for instance: assembling a jigsaw puzzle). This condition is from either the cold-shoulder defect in the brain that creates a sparseness of tissue in the visual systems of the brain. a team of investigator at the National Institute of Mental Health used functional magnetic resonance imaging (fMRI) to watch a blood flow of the brains of line 3 text cases when it were performing 2 tasks involving spatial relations. Souls sustaining Williams syndrome showed weaker activity in the subdivision of the brain associated using spatial relations. Scans of brainside anatomy of end line text cases sustaining Williams indicated the deficit of brain tissue in an front yard of the equivalent division of the brain mentioned above. This deficit part bars transmission of ocular data to the spatial relations region of the brain. In a line 1 text, everthing participants of a survey measured in the norm intelligence range to dislodge the possibility that the retardation aspect of Williams syndrome will will have an symptom on the visual systems of the tested people.
