Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a retrospective biobank study evaluating the impact of novel genetic variants in a population of 6-mercaptopurine treated pediatric acute lymphoblastic leukemia patients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study objective is to clinically validate that the presence of recently discovered novel genetic variation adversely affects a population of 6-mercaptopurine treated pediatric acute lymphoblastic leukemia patients using biobank samples.
