We also sequenced BRAF in 52 samples and found point mutations affecting the hot spot codon 600 in exon 15 of BRAF, V600E (an activating mutation previously described in melanomas and other cancers (Wan et al, 2004)) only in 1 JPA and 1 grade II ganglioglioma (Tables 1, 2a and b; Supplementary Table 3) in keeping with previous studies (Jeuken et al, 2007; Jones et al, 2008; Pfister et al, 2008). The gene discussed is BRAF; the disease is ganglioglioma.
