This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The purpose of the study is to identify how many patients w/ Noonan syndrome, patients w/ a Noonan-like syndrome, or patients with one of the heart problems seen in Noonan syndrome (pulmonary valve disease or hypertrophic cardioyopathy) have a mutation (a change in the structure) in the PTPN11 gene. These mutations can be passed down in families. Addionally, we are interested in the medical problems and physical exam features of the participants in the study. We would like to compare the mutations (gene changes) found and the medical problems participants have to see if certain mutations are related to certain medical problems or physical features.
