A novel BCR-ABL transcript (e8a2) with the insertion of an inverted sequence of ABL intron 1b in a patient with Philadelphia-positive chronic myeloidleukaemia
S. Branford et al., A novel BCR-ABL transcript (e8a2) with the insertion of an inverted sequence of ABL intron 1b in a patient with Philadelphia-positive chronic myeloidleukaemia, BR J HAEM, 109(3), 2000, pp. 635-637
An atypical BCR-ABL transcript in a patient with Philadelphia (Ph)-positive
chronic myeloid leukaemia (CML) was detected using a long polymerase chain
reaction technique, Sequence analysis revealed a joining of BCR exon e8 an
d ABI, exon a2, with a 55-base pair (bp) insert of an inverted sequence of
ABL intron Ib between them, giving rise to an in frame e8a2. BCR-ABL transc
ript, This is the first report of a BCR-ABL transcript with the insertion o
f an inverted sequence. The long PCR technique is a useful screen for atypi
cal RCR-ABL transcripts not detected by standard techniques.
