Two groups have discovered recurrent mutations in the promoter of telomerase reverse transcriptase (TERT) in a large proportion of sporadic melanomas, as well as in a large, melanoma-prone family. The mutations create binding sites for ETS transcription factors, leading to increased transcription of TERT. The high frequency (more frequent than BRAF and NRAS mutations) and mutually exclusive nature of these mutations suggest that this may represent a driver mechanism in melanoma.
