Gene expression profiling of Angioimmunoblastic T-Cell lymphoma (AITL) tumors

Angioimmunoblastic T-Cell lymphoma (AITL) is a mature T-cell lymphoma of blood or lymph vessel immunoblasts. It is the most common subtype of T-cell lymphoma in the Western world and the second most frequent one in Asia. We sequenced nine pairs of AITL exomes and their matched normals. Frequent mutations in TET2 and RHOA were detected, and confirmed through targeted sequencing in a larger cohort of 43 samples. Gene expression profiling was performed to identify genes differentially expressed between patients with and without mutations in genes of interest.
