Sotos is a genetic condition caused by a change on chromosome 5. Children diagnosed with Sotos syndrome have characteristic facial features, overgrowth in height, weight and head size, and delays in their motor, cognitive and social development. Their speech is difficult and they have low muscle tone, which can affect feeding, and movement. The prevalence of Sotos is 1 in 14,000. Sotos is sometimes referred to as cerebral gigantism. Sotos is usually diagnosed months or years after birth.
