Expression of HMGA2-LPP and LPP-HMGA2 fusion genes in lipoma: identification of a novel type of LPP-HMGA2 transcript in four cases..     ///    "In addition to the HMGA2-LPP fusion gene, the LPP-HMGA2 fusion gene could have some specific roles for lipomagenesis. "    ///    "Although the expression of HMGA2-LPP fusion gene has been reported in lipomas, the reciprocal LPP-HMGA2 fusion gene has rarely been described. "    ///    Ninety-eight cases of lipoma were analyzed for the possible expression of HMGA2-LPP and LPP-HMGA2 fusion genes using a reverse-transcription polymerase chain reaction method.     ///    "Ten lipomas (10%) revealed both HMGA2-LPP and LPP-HMGA2 fusion transcripts, nine (9%) only HMGA2-LPP, and three (3%) only LPP-HMGA2. "    ///    The biological implications of the expression and the variation of LPP-HMGA2 fusion transcripts need to be elucidated..     ///    "Out of 13 lipomas with LPP-HMGA2 transcript, 9 were associated with a previously reported LPP-HMGA2 fusion transcript, which fuses exon 8 of LPP to exon 4 of HMGA2, while 4 with a novel type of LPP-HMGA2 fusion transcript, which fuses exon 7 of LPP to exon 4 of HMGA2. "    ///    "DNA sequencing analysis demonstrated that the HMGA2-LPP transcript in 19 lipomas consisted of exons 1-3 of HMGA2 and exons 9-11 of LPP, which was described previously. "
