International 15q Day

November 15th is International 15q Day!

Together with Angelman Syndrome Foundation and International Prader-Willi Syndrome Organization, Dup15q Alliance is raising awareness of the similarities between chromosome 15q duplication, Angelman and Prader-Willi syndromes. Join us on November 15th to help raise awareness and support for these related disorders.

Why November 15th?

The genetic complications within Dup15q, Angelman and Prader-Willi all originate from the q11-q13 region of the 15th chromosome, commonly written as 15q11-q13. This directly correlates to November 15, 2013 written in numerical form: 15.11.13. This only happens once every hundred years, so we have joined forces to create International 15q Day on November 15th!

Same Difference.

Dup15q, Angelman and Prader-Willi are different disorders, but each is caused by genetic variations within the q11-q13 region of the 15th chromosome. The three disorders share overlapping symptoms and because of insufficient awareness, they are commonly misdiagnosed for one another.

Here how the symptoms of each disorder relate to one another. 


How can you help?
