NF1 and neoplasm: BRAF subtype (81% BRAF subtype tumors with Breslow thickness <1 mm–4 mm) and Triple WT tumors (58% Triple WT with Breslow thickness <1 mm–4 mm) were associated with thin to intermediate tumor thickness and thicker tumors were associated with the NF1 (72% with Breslow thickness >4 mm) and RAS subtypes (69% with Breslow thickness >4 mm).
