SNP-Based Prediction of Oral Mucositis Risk in Patients Receiving Hematopoietic Stem Cell Transplants (HSCT)

Subjects will be provided with a saliva collection kit which can be used at home. Subjects will return the collection kit in a paid, pre-addressed mailer to the laboratory at Biomodels. The laboratory will isolate and store the DNA located in the cells of the saliva. A portion of this DNA will be used to analyze the different forms of genes. The remainder of the DNA will be destroyed when this study is completed. Biomodels will not be provided with patient identifiers. The investigators will also collect information from medical records, including information about diagnosis, treatment, stem cell transplantation and post-transplantation outcomes. This information will be de-identified.
