title: [Deletions and aberrant transcription of p16 and p15 genes in childhood acute lymphoblastic leukemia].
abstract: OBJECTIVE
  To explore the role of p16(MTS1) and p15(MTS2) genes in the pathogenesis of childhood acute lymphoblastic leukemia(ALL).
  
  
  METHODS
  PCR and Southern blot were used to analyse p16 and p15 gene deletions, RT-PCR was used to analyse p15 gene transcription.
  
  
  RESULTS
  Exon 1 and 2 of p16 gene deletion was detected in 8 of 21 patients(38.1%), and exon 1 and 2 of p15 gene deletion in 11 of 21 patients(52.3%). Aberrant p15 gene transcription was observed in two cases.
  
  
  CONCLUSIONS
  High frequency of p16 and p15 gene deletions and aberrant transcription may be involved in the pathogenesis of childhood ALL.
