Monoclonalities detected by polymerase chain reaction (PCR) in the T-cell receptor genes

Chain	Region to which PCR was applied	Bone marrow	Peripheral blood
β Chain	Vβ/Jβ1,2	Positive	Positive
	Vβ/Jβ2	Positive	Positive
	Dβ/Jβ	Positive	Positive
γ Chain	Vγ If, Vγ10/Jγ	Positive	Positive
	Vγ 9, Vγ11/Jγ	Positive	Positive
δ Chain	Vδ/Jδ	Positive	Marginal

Positive: monoclonality was detected. Marginal: the peak of PCR was noticeable but its height was lower than the positive control. The methodology is described in detail in [21].
