Microarray analysis in 18 melanocytic nevi with and four nevi without the BRAFV600E mutation revealed 92 upregulated genes in nevi with the BRAF mutation, including the lncRNA paternally expressed gene 10 (PEG10) [82], thus suggesting that gain of PEG10 expression might occur early during BRAF‐mutant CM development. Here, BRAF is linked to cutaneous mastocytosis.
