Associated Genetic Biomarkers


NCI Definition: A T-cell peripheral neoplasm characterized by a persistent (>6 months) increase in the number of peripheral blood large granular lymphocytes, without a clearly identified cause. (WHO, 2001) [1]

T-cell large granular lymphocyte leukemias most frequently harbor alterations in STAT3, TET2, KMT2A, WT1, and TNFAIP3 [2].

Most Commonly Altered Genes in T-Cell Large Granular Lymphocyte Leukemia

STAT3 Mutation, STAT3 Exon 21 Mutation, TET2 Mutation, STAT3 Y640F, and TET2 Nonsense are the most common alterations in T-cell large granular lymphocyte leukemia [2].
