General Discussion

Sotos syndrome is a variable genetic disorder characterized by excessive growth before and after birth. One of the major features of Sotos syndrome is a particular facial appearance that includes facial flushing, an abnormally prominent forehead (frontal bossing), down-slanting eyelid folds (palpebral fissures), prominent, narrow jaw, a long narrow face and a head shape that is similar to an inverted pear. Height and head circumference are measured to be greater than average for most affected children. Developmental delays are present in most children with Sotos syndrome and can include motor and language delays as well as mental retardation ranging from mild to severe. Other problems associated with Sotos syndrome include jaundice in newborns, curved spine (scoliosis), seizures, crossed eyes (strabismus), conductive hearing loss, congenital heart defects, kidney abnormalities and behavioral problems. Affected individuals also have a slightly increased risk to develop specific types of tumors. Sotos syndrome is caused by an abnormality (mutation) in the NSD1 gene.
