Chromosome 9 P Minus Syndrome

Description

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.

Conditions

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * Having 9P minus syndrome/ deletions on the 9th chromosome
  • * Parents and siblings of affected individuals may also be included to determine contribution of genetic background to phenotypic characteristics
