Methodology

Test Description

Bi-directional sequencing of exons 2-7 of the ETV6 gene (formerly called TEL). This assay detects sequence variants rather than ETV6 translocations.

Clinical Significance

ETV6 translocations are implicated in leukemias, myelodsyplastic syndrome (MDS), and sarcoma. Mutations within the ETV6 gene, such as those detected by this assay, are detected in acute lymphoblastic leukemia (ALL) and approximately 3% of MDS. ETV6 mutations have been shown to be independent predictors of poor prognosis in MDS.
