Abstract:
The variable heavy chain region (VH) genes of 3 untreated patients with B-cell chronic lymphocytic leukemia (B-CLL) were cloned and analyzed. The VH family used was VH3-11, VH3-72 and VH3-33. More than 2% difference from the corresponding germline gene was detected in all the 3 obtained potential functional genes (average 16.7). Mutation pattern analysis indicated evidence of antigen selective pressure observed in 1 of 3 cases. Our findings suggested that the tumor cells originate from post-GC cells.
