There is no study design for this protocol. Samples obtained under IRB/IEC-approved protocols that clearly permit storage of patient material at SJCRH will be banked, provided proof of informed consent is available. Such samples will be tagged accordingly and will be only released to fulfill the aim(s) of the protocol under which they were obtained, or to investigators that apply to the St. Jude Children's Research Hospital Tissue Resources Committee to use the samples.
