title: [Detection of IgVH mutation status in patients with chronic lymphocytic leukemia by multiplex PCR].
abstract: IgVH mutation status is one of the most important independent prognostic factor of chronic lymphocytic leukemia (CLL). In order to evaluate IgVH mutation status in patients with CLL, IgVH mutation was detected by multiplex PCR in 9 CLL patients and purified PCR amplification products were directly sequenced, IgH somatic hypermutation and mutation site were analysed by IMGT/V-QUEST. The results showed that 5 patients had mutated IgVH, and IgVHs were IGHV3-11*03, IGHV3-9*01, IGHV3-23*01, IGHV4-59*01, IGHV4-34*02, respectively; whereas 4 others had unmutated IgVH, these IgVHs were IGHV3-53*01, IGHV3-23*03, IGHV3-33*05 and IGHV3-7*01. It is concluded that multiplex PCR is a rapid and easy method to detect IgVH mutation status, and it solves the limitations and pitfalls of routine PCR, and it is worth being extensively used both in clinic and scientific researches.
