Latest Registry Report Download Report

Simons Searchlight just released a new report that includes updated information on your genetic community. The report also focuses on development using a survey called the Vineland Adaptive Behavior Scales. Caregivers share how their family members with our genetic condition respond to different skills like communication, self-care, and social skills. This survey helps doctors and researchers understand how our skills change over time.

If you want to help contribute to this research, it’s important to participate in surveys. To view past registry reports and learn more, go to the Simons Searchlight website and click on “Previous Registry Reports.”

People who have 7q11.23 duplication syndrome may look different. Appearance can vary and can include some but not all of these features:

Wide, flat head shape
Wide forehead
Straight eyebrows
Deep-set eyes
Long eyelashes
Wide-tipped nose

MOVEMENT

Almost three-quarters of people who have 7q11.23 duplication syndrome have difficulty or delay in learning motor skills, also called developmental coordination disorder.

HEART

Almost one-half have heart issues,, most often a large artery,, also known as dilation of the ascending aorta.
