Epidermal, sebaceous, and melanocytic nevoid proliferations are spectrums of mosaic RASopathies.

Abstract excerpt

Growing evidence demonstrates that various nevoid proliferations such as keratinocytic epidermal nevi and nevus sebaceous result from somatic mosaicism. Many of the mutations identified have been within the RAF/RAS/MAPK pathway, hence supporting the previously introduced term "mosaic RASopathy" for these nevi. In this issue, Kinsler et al. were among the first to characterize certain pigmented melanocytic nevi...
