Are there people with a 22q11.2 duplication who have no speech, behavior, learning, or health problems?

Yes. The 22q11.2 duplication can be ‘silent’, or at least there may be no signs or symptoms that make a person stand out from the rest of their family. We know this because some parents and siblings of children with a 22q11.2 duplication have the same duplication, but do not have any obvious unusual features or delayed development - at least not to the point where they need medical or educational intervention. The effect of genetic conditions such as a 22q11.2 duplication on development, health and behavior ranges from being barely noticeable to being obvious and severe.[1]
