DUPD1
Dup1: A Comprehensive Guide
Description:
Duplicated segmental amplification of the proximal long arm of chromosome 15 (15q11-q13) is known as Dup1. This rare genetic condition occurs when an individual possesses extra copies of a specific region of chromosome 15. The size of the duplicated segment can vary, leading to a range of symptoms and severity.
Associated Diseases:
Dup1 is associated with a spectrum of medical conditions, including:
- Angelman syndrome (characterized by developmental delays, speech impairments, and distinctive facial features)
- Prader-Willi syndrome (marked by hypotonia, short stature, intellectual disability, and hyperphagia)
- Autism spectrum disorder
- Developmental delays
- Epilepsy
- Obesity
- Psychiatric disorders
Did you Know ?
The prevalence of Dup1 is estimated to be approximately 1 in 30,000 individuals worldwide. However, due to the variable size and penetrance of the duplication, the exact number of affected individuals may be higher.
