What behaviors might be observed in people with trisomy 18p (chromosome 18p duplication)?

Because of the limited data published on chromosome 18p duplication, we were unable to locate information that discusses behaviors which might be observed.

We recommend you contact the nonprofit support and advocacy groups located in the "Organizations" section of the GARD resource page on chromosome 18p duplication, as these groups may have families of people with trisomy 18p registered with them. The members of these advocacy groups might be able to share information regarding behaviors present in their family members.

How might chromosome 18p duplication be treated?

Because the presence and severity of signs and symptoms vary from person to person, treatment also varies. If an intellectual disability and/or developmental delay is present, early educational intervention and early services are important.

It is essential to work with one's person's health care provider and medical team to determine the appropriate medical management plan.
