CEBPA Mutation Analysis - Germline
Test Information: Sequencing analysis of germline cells for the region(s) containing the mutation(s) identified in tumor samples
Test Details
Test Code: 9085
Special Notes: The CEBPA (CCAAT/enhancer binding protein a) gene is a transcription factor that regulates proliferation and controls terminal granulocytic differentiation. Functional alterations in CEBPA have been identified in acute myeloid leukemia (AML). Recent work has shown that mutations of CEBPA are associated with favorable prognosis in both adult and pediatric AML in the absence of associated cytogenetic abnormalities and FLT3 internal duplication (FLT3-ITD). Latest evidence showed that Germline CEBPA mutations cause dominant inheritance of AML.

This test can be performed if there is a previously identified mutation(s) in CEBPA Mutation Analysis performed on tumor tissue (#9086). If the original novel mutation(s) was identified in another laboratory, this testing must be discussed with one of our genetic counselors prior to sending a specimen.

Technical Limitations:

This test is designed to distinguish germ line mutation from somatic mutation. The limit of the test is approximately 20 mutated cells in 100 total cells (20%).
Results of this test must always be interpreted in the context of relevant clinical and pathological data, and should not be used alone for a diagnosis of malignancy. This test is not intended to detect minimal residual disease.
Useful Publications:
