Dup 15q Syndrome

Community, Stories & Info


Dup15q syndrome, or Chromosome 15q11.2-13.1 duplication syndrome, is a neurodevelopmental disorder that is caused by the partial duplication of chromosome 15. The disorder confers a strong risk for epilepsy, autism spectrum disorder (it is the most common genetic cause), and intellectual disability, and causes delays in motor, cognitive and language development. In most cases, the chromosome mutation is not inherited but occurs during formation of reproductive cells or during embryonic development.

Organizations exist to provide support and resources to individuals experiencing Dup15q in their lives.
