Because mosaic trisomy 9 affects many different systems of the body, medical management is often provided by a team of doctors and other healthcare professionals. Treatment for this condition varies based on the signs and symptoms present in each person. For example, children with bone or muscle abnormalities and/or delayed motor milestones (i.e. walking) may be referred for physical or occupational therapy. Depending on the degree of intellectual disability, a child may require special education classes. Heart defects and cleft lip and/or palate may need to be surgically repaired. Children with hydrocephalus may be treated with certain medications and/or shunting (placement of a specialized device that drains excess fluid away from the brain). Other surgeries may be recommended depending on the nature and severity of the other features (i.e. craniofacial, muscular, skeletal, kidney, and/or reproductive system problems) and their associated symptoms.
