Chronic lymphocytic leukemia driven by paradoxical ERK activation during BRAF inhibitor treatment
Whole-exome sequencing of a chronic lymphocytic leukemia (CLL) developed during vemurafenib treatment of a patient with malignant melanoma. Peripheral blood mononuclear cells were separated by Ficoll gradient centrifugation. DNA was extracted from highly purified (>97%) CD19+CD5+ cells obtained from the patient while being under BRAF inhibition versus CD14+ germline control cells (>90% purity). No alterations that could be linked to aberrant RAS activity or paradoxical RAF/MEK/ERK signaling could be identified in the CLL, which shows characteristic copy number alterations.

Data Transfer Agreement for the German Cancer Research Center
To request access to the dataset please start a Data Access Request via the EGA DAC Portal. You will receive a HIPO DACO Info Form to collect information about the request, which has to be filled and signed. Your request will be evaluated by the responsible Data Access Committee (DAC). As soon as a positive decision is made, you will be provided with a data transfer agreement (DTA). After the DTA has been fully signed, access to the requested data is granted.
Studies are experimental investigations of a particular phenomenon, e.g., case-control studies on a particular trait or cancer research projects reporting matching cancer normal genomes from patients.
