Desmoplastic melanomas most frequently harbor alterations in NF1, TP53, KMT2D, KMT2C, and IL7R .
NF1 Mutation, TP53 Mutation, KMT2D Mutation, NF1 Nonsense, and KMT2C Mutation are the most common alterations in desmoplastic melanoma .
There is 1 clinical trial for desmoplastic melanoma, of which 1 is open and 0 are completed or closed. Of the trial that contains desmoplastic melanoma as an inclusion criterion, 1 is phase 2 (1 open).
