NF2 and schwannoma: SWN has a phenotypic overlap with NF2, characterized by the presence of schwannomas, but without VS development (MacCollin et al., 2005) and with distinct underlying genetics (Plotkin et al., 2022), including mutations identified in SMARCB1 and LZTR1 (Hulsebos et al., 2007; Piotrowski et al., 2014).
