About this study

Patients with deletion of chromosome 9 P are rare (\~200 in the medical literature) and have a diverse set of phenotypic characteristics. We propose using state of the art genome sequencing methods to define the location and size of the deleted portion of chromosome 9 P as well as the genetic background in affected patients (whole genome sequencing) and correlate the genes in the deleted portion of chromosome 9 P with specific phenotypic characteristics of each patient. Enrolled participants will be asked to complete a detailed questionnaire, complete a medical release form, and provide a biospecimen sample.
