MALT1_API2t(11;18)(q21;q21) / 15337797MALT lymphoma;lymphoma - - The presence of t(11;18)(q21;q21) was identified by a multiplex reverse transcriptase polymerase chain reaction of the API2-MALT1 chimeric transcript. /// The API2-MALT1 fusion transcript was detected in only one (12.5%) of eight H.
MALT1_API2- 15363040MALT lymphoma;B cell lymphoma;lymphoma - - Therefore, detection of API2-MALT1 fusion transcripts is useful for evaluating the prognosis and clinical behavior of the disease.. /// "Expression of API2-MALT1 fusion transcripts was detected by reverse transcription-polymerase chain reaction analysis using formalin-fixed, paraffin-embedded tissue. " /// Intestinal MALT lymphomas with API2-MALT1 expression have distinctive forms of infiltration compared with those without translocation.
MALT1_API2- 25381826MALT lymphoma ISH - Two months later, pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma was confirmed by the detection of API2-MALT1 translocation in fluorescent in situ hybridization analysis.
MALT1_API2- 19907113B cell lymphoma;lymphoma ISH - There was no API2-MALT1 fusion transcript in any of the eight cases examined.
