An immunoglobulin (Ig) gene rearrangement can be identified in all of the following acute lymphoblastic leukemias except:
A) Pro-B
B) Common ALL
C) Pre-B
D) Precursor T

Question

Quizplus · Accepted Answer

Precursor T acute lymphoblastic leukemia does not involve Ig gene rearrangements, as T cells do not produce immunoglobulins. The other types of acute lymphoblastic leukemias (Pro-B, Common ALL, Pre-B) involve Ig gene rearrangements because they originate from B cells, which produce immunoglobulins.
