Noonan syndrome

Stanford University

Seeking participants
Study of brain and cognitive development in boys and girls with Noonan syndrome

The project is a pilot study looking at Noonan Syndrome in children (ages 4-11). We are hoping to recruit ten families of children with a confirmed PTPN11 mutation to participate in a two-day visit to Stanford University, which will include neuropsychological testing and an MRI. Families who choose to participate will have travel arrangements covered by the study, and will receive a summary of the testing results for participating and a small monetary honorarium for participating.

Social-Emotional Development in Children with Noonan Syndrome 

Parents of children and adolescents with Noonan syndrome between the ages of 8 and 16 are invited to participate in a new research study!

The purpose of the study is to characterize social development in individuals with Noonan syndrome and related disorders, and to understand how emotional and behavioral development can impact interpersonal relationships. Children with Noonan syndrome and their unaffected siblings are eligible to participate.

Study participants will be asked to complete a set of questionnaires that inquire about their family background, their child’s social development, and their child’s emotions and behavior. Forms will be completed by both parents and children. Families will also be asked to sign a release of information form so that the researchers can request records to confirm the child’s diagnosis of Noonan syndrome as well as genetic testing related to that diagnosis.

Completing the study questionnaires and forms will take approximately one hour of your time.

Please contact us for more information! The study is being conducted by Dr. Rene Pierpont, Dr. Rebekah Hudock, Dr. Peg Semrud-Clikeman and Dr. Christopher Moertel at the University of Minnesota.

The Neurofibromatosis Type 1 Patient Registry (NPR1) is currently recruiting both adults and children with NF1 for a childhood brain tumor study.  The goal of this study is to identify differences in medical, social, demographic, and birth characteristics of children who develop childhood brain tumors compared to those who do not develop these tumors.  We are looking for individuals with NF1 who either (1) HAVE previously been diagnosed with a brain tumor younger than age 18 years or (2) HAVE NEVER had a brain tumor.  For more information click here:

Completing the online questionnaire/registration will take approximately 30 minutes of your time.

A sleep research study to help develop a new pediatric sleep health survey to better understand how sleep health relates to RASopathies.

For parents of individuals with a RASopathy to complete a 10-15 minute online survey.  Affected children between the ages of 8 and 17 may be able to participate in the study by answering the survey, as well. Anyone who understands English is eligible to participate (it is not limited to the United States).
