The KIAA1549-BRAF fusion gene has been found in approximately 70% of PAs, but is reportedly rare in PMAs.    ///    "The KIAA1549-BRAF fusion gene has been found in approximately 70% of PAs, but is reportedly rare in PMAs. "    ///    Three major KIAA1549-BRAF fusion subtypes were analyzed by quantitative reverse transcription polymerase chain reaction(RT-PCR)and sequencing.     ///    "In summary, no BRAF V600E mutations were found in PMSAs, but KIAA1549-BRAF fusion was identified in IPT, particularly in the PA component.
