Williams syndrome is the result of a deletion of the 7q11.23 region of chromosome #7 containing the elastin gene and is believed to be a contiguous gene syndrome. Diagnosis of Williams syndrome is confirmed by dual colour FISH using a specific probe and a control probe.
Children with Williams syndrome tend to be small for their age and reach their final adult height early. One study found that the average height in females was 152 cm, and in males 165 cm. Early onset of puberty is relatively common, particularly in girls.
