The Asp638Glu variant in BRAF has been reported to have occurred de novo in two individuals with clinical features of Cardio-facio-cutaneous syndrome (Sarkozy 2 009, Kleefstra 2011). Another variant at this nucleotide position resulting in the same amino acid residue change has also been reported in two individuals wit h clinical features of Cardio-facio-cutaneous syndrome including one de novo occ urrence (Sarkozy 2009, Rauen 2006). This variant was not identified in large po pulation studies. Studies have shown that the Asp638Glu variant impacts protein function (Rodriguez-Viciana 2008). In summary, the Asp638Glu variant meets our c riteria to be classified as pathogenic (http://pcpgm.partners.org/LMM) based upo n its de novo occurrence in affected individuals, low allele frequency in the ge neral population, and supporting functional evidence.
