NF1 is a RAS GTPase activating protein (GAP) that promotes the conversion of the active RAS:GTP to the inactive RAS:GDP form (reviewed in King et al, 2013). Germline loss-of-function mutations in NF1 are associated with neurofibromatosis 1, an autosomal dominant disorder that causes aberrant activation of the RAS signaling pathway (reviewed in Tidyman and Rauen, 2009). More recently, somatic loss-of-function mutations in NF1 have been identified in a number of cancers such as glioblastoma, lung adenocarcinoma, breast and ovarian cancers, leukemia and neuroblastoma, making NF1 a tumor suppressor (Cancer Genome Atlas Research Network, 2008; Parsons et al, 2008; McGillicuddy et al, 2009; Ding et al, 2008; The et al, 1993; Holzel et al, 2010; Maertens et al, 2013; Whittaker et al, 2013; reviewed in Maertens and Cichowski, 2014). Cancer-associated lesions in the NF1 gene range from homozygous deletions of the entire gene to missense or frameshift mutations that truncate and destabilize the protein; these variant alleles are often expressed at very low levels or not at all and where examined, most cells appear to have compromised GAP activities (Basu et al, 1992; De CLue et al, 1992; Bollag et al, 1996; Klose et al, 1998; Updahyaya et al, 1997; Krauthammer et al, 2015; Nissan et al, 2014; Thomas et al, 2012; reviewed in Maertens and Cichowski, 2014).
