What Is 2q37 Deletion Syndrome?
2q37 deletion syndrome is a chromosome disease that can affect many parts of the body. About 100 cases have been reported worldwide. This condition is characterized by short stature, weak muscle tone (hypotonia) in infancy, mild to severe intellectual disability and developmental delay, autistic behavior, obesity, characteristic facial features, and other physical abnormalities, such as short bones of the hand and of 3-5 fingers, and abnormal lateral curvature of the spine (scoliosis). Other findings include seizures (20%-35%), congenital heart disease, brain abnormalities (hydrocephalus, dilated ventricles), umbilical/inguinal hernia, tracheomalacia, gastrointestinal abnormalities, and kidney malformations. 2q37 deletion syndrome is caused by a deletion of the genetic material from a specific region in the long (q) arm of chromosome 2. Most cases are not inherited. Treatment depends on the symptoms and may require several specialists.
