This disorder can lead to a variety of symptoms, including developmental delay, intellectual disability, and autism spectrum disorder. The severity of symptoms can vary widely among individuals with Dup15q.

Causes[edit | edit source]
Dup15q is caused by the presence of an extra copy (or copies) of a specific region on chromosome 15. This can occur in one of two ways:
- Interstitial Duplication: An extra copy of the region is located within the long arm of one of the two chromosome 15s.
- Isodicentric Duplication: An extra copy of the region is located on a supernumerary chromosome, which is made up of two copies of the long arm of chromosome 15.
Diagnosis[edit | edit source]
The diagnosis of Dup15q is typically made through genetic testing, which can identify the presence of the extra copy of the region on chromosome 15.
Treatment[edit | edit source]
There is currently no cure for Dup15q. Treatment is focused on managing the symptoms and improving the quality of life for individuals with the disorder. This may include:
- Physical therapy
