17q12 Project

Patients & Caregivers

Children and adults who have a 17q12 deletion are missing a small section of genetic material from one copy of their number 17 chromosomes, while those with a 17q12 duplication have an extra section of genetic material in the same region. This section of chromosome 17 contains several genes that are known to cause symptoms when they are deleted or duplicated. People with 17q12 deletions are at risk for developmental and language delays, autism spectrum disorder, mental illness, motor coordination issues, kidney problems, and a specific type of diabetes. We know less about the behavioral and health characteristics associated with 17q12 duplications. Not every person with a 17q12 deletion or duplication will experience the same symptoms, and some people may not notice obvious effects.

As researchers and health care providers at Geisinger’s Autism & Developmental Medicine Institute (ADMI), we are interested in better understanding the behavioral, developmental, and medical characteristics associated with extra or missing material in the 17q12 chromosomal region. If you or your family member has been diagnosed with a 17q12 deletion or duplication, please contact Hallie Andrew at ehandrew1@geisinger.edu or 570-214-0168 for more information about how to participate in our ongoing research studies. Your participation helps increase our knowledge about 17q12 deletions and duplications, with the goal of improving the lives of affected individuals and their families. You may also be interested in registering with the 17q12 Interest Group.


On June 26 & 27, 2015, genetics and medical specialists from Geisinger Health System hosted the second annual family meeting on 17q12 deletions and duplications in Philadelphia, PA. See below for the presentations from recent family meetings as well as links to recent newsletters.
