Clonality definition
WebSep 11, 2024 · For traditional bulk TCR sequencing studies, clonotypes are generally defined based on identical CDR3 (the complementarity determining region 3) sequences of TCR α- or β-chains, owing to technological limitations. WebThe detection of clonality does not always imply the presence of a malignancy. Some clinically benign proliferations could have a clonal origin (e.g. benign monoclonal gammopathies). False-negative results might be possible due to improper primer annealing.
