Li L et al. examined the sequence and expression of ICAM3 transcript variants 1-4 in diffuse large B-cell lymphoma (DLBCL) cells and tumor tissues, and showed that the variant 1 is the longest variant which has 1644 base pair (bp) and correspondingly 547 Amino Acid (AA), the molecule weight is 60kDa. The gene discussed is ICAM3; the disease is diffuse large B-cell lymphoma.
