While patients can live productive lives, they still face many difficulties in terms of their health and social skills.
This condition is caused by the deletion of several genes located on the long arm (q arm) of at least one strand of chromosome 7. Some of these genes include LIMK1, CLIP2, and NCF1.

Facial deformity is a distinct phenotype of patients with Williams syndrome. These facial deformities consist of a flattened nasal bridge, ridges in the skin, and extra skin around the inner corners of the eye. Patients can also suffer from the following: dental abnormalities, attention deficit disorder, incoordination, poor calcitonin metabolism, microcephaly, kidney disease, and bladder disease (Bartke & Siegmuller, 2004, p. 4p-4q) (Williams syndrome, 2008). Learning and speaking disabilities are prevalent at varying degrees. However, there have been reported cases of Williams syndrome patients displaying outstanding intellectual and speaking abilities later in life. They are even known to excel in music (Williams syndrome, 2008). Although patients are known to have difficulties navigating through social cues, they are typically very friendly and trusting of
