Clonality evaluation in human tissues

Abstract

Malignant proliferations are usually clonal. While most times the biological potential can be established through routine pathologic and clinical examinations, some cases are difficult to classify. Moreover, in some situations there are dominant clones whose analysis is important, such as in autoimmune diseases and immunodeficiency. This paper presents in an understandable way the main techniques for the study of clonality, namely: evaluation of gene rearrangements of antigen receptor, and evaluation of human antigen receptor gene.
