EVIDENCE SUMMARY |
There was only sufficient evidence in the literature for the RAF1:NSML association to be classified as Limited. Only two variants with supporting evidence for pathogenicity (one de novo) in the gene have been found in individuals with NSML (Carcavilla et al., 2013; Kuburovic, Vukomanovic, Carcavilla, Ezquieta-Zubicaray, & Kuburovic, 2011; Pandit et al., 2007). The RAF1 gene is also located in the Ras/MAPK pathway which is associated with the NSML phenotype (Aoki et al., 2016; Rauen, 2013).
