Primary Outcome Measures:
  • Identification of unique mutations through whole-genome sequencing

Estimated Enrollment: 10
Study Start Date: February 2012
Primary Completion Date: May 2016 (Final data collection date for primary outcome measure)
Detailed Description:


  • To identify new genetic abnormalities associated with acute myeloid leukemia (AML) in patients with Down syndrome through whole-genome sequencing.
