Welcome to HCM This is Dr Amit. Let me help you in this case Sotos syndrome is a genetic condition causing physical overgrowth during the first years of life. Children with Sotos syndrome are often taller, heavier, and have larger heads than their peers. Because of the distinctive head shape and size sotos syndrome is sometimes called cerebral gigantism. The disorder may be accompanied by autism,mild mental retardation, delayed motor, cognitive, and social development, hypotonia (low muscle tone), and speech impairments Affected infants and children tend to grow quickly. There is no standard course of treatment for Sotos syndrome. Treatment is symptomatic. And yes sotos syndrome is not a life-threatening disorder and patients may have a normal life expectancy. However coordination problems may persist into adulthood, along with any learning disabilities Feel free to ask if you have any other query Regards
