This study is being conducted for research purposes in order to identify young people who have specific gene variation(s) that may affect ADHD. Normally, each person inherits 2 copies of each gene, one from mom and one from dad. Sometimes, your child may inherit extra copies of those genes and sometimes, they may inherit less. We are trying to see if your child’s DNA has a specific variation that we will look at further in this and future studies.

Your child can’t be pregnant or breastfeeding to be in this study. If eligible, you need to electronically sign an informed consent form to have a saliva kit sent to your home through the mail.

You and your child will follow the directions located in the kit to provide a saliva sample. The sample will get placed in the packaging provided and returned to the Children’s Hospital of Philadelphia in the mail. The sample will then be tested to see if your child has specific gene(s) of interest. If you indicated that you would like your child to participate in the study of an investigational medicine if eligible, the results will be referred to a doctor in your area whose staff will contact you for possible participation.
