KNSTRN and cutaneous melanoma: Intriguingly, we also found C>T missense mutations in the KNSTRN gene, previously implicated in human cutaneous squamous cell carcinoma27, in 1 cutaneous melanoma (L27F in HD0004a) and two mucosal-like samples with a high mutation rate and UV signature (L27F in HD0021a, and P28L in HD0032a).
