A run/walk fundraiser at Interlake High School on Sunday, May 4 will help provide awareness and support for a rare condition that affects about 900 people worldwide – and about a dozen in western Washington.

The Dup15q Alliance is an international organization that supports people with a duplication on the 15th Chromosome (15q 11.2-13.1). Children with the condition frequently are affected by developmental disabilities, including autism spectrum disorders and cognitive disabilities. They frequently have other issues such as seizure disorders, low muscle tone, and a number of others.

In addition to raising money, the event is designed to bring families together so that they can feel the support of the community as they are challenged with the physical and emotional needs of their children. Several hundred people are expected at the event.

Participants will run or walk around the Interlake High School track. It’s non-times and strollers are OK. A “bouncy house” will be available for kids and snack will be provided.

Registration fee is $15 and additional donations are welcome. Register for the event at www.dup15q.org/seattlewalk.html.

Check-in will be at 9:30 a.m. with the walk beginning at 10″30 a.m.

Interlake is located at 16245 N.E. 24th St., Bellevue.
