In addition to fusions implicating the NF2 gene, other fusion transcripts were observed in more than one meningioma sample including C10orf112-PLXDC2 (found in I NP, I P, and grade III); GAB1-HHIP-AS1 and HHIP-AS1--GAB1 found in a I NP sample; KANSL1-ARL17A (found in two I NP, two de novo grade II, one secondary grade II, and one grade III); MLLT3-CNTLN (one de novo grade II and two secondary grade III); RP11-444D3.1-SOX5 (two grade I NP, one grade III); and SAMD5-SASH1 (found in four grade I NP samples) (as summarized in Table 4). Here, GAB1 is linked to meningioma.
