Cutaneous melanoma (CM) is the most dangerous form of skin tumour and causes 90% of skin cancer mortality1. With recurrent somatic mutations in BRAF, NRAS, KIT and NF1 among the most common genetic aberrations underlying pathogenesis of melanoma, next generation sequencing (NGS) has been an invaluable tool in helping to characterise the overall genomic landscape of melanomas.

The most frequently activated pathway in melanoma is the mitogen-activated protein kinase (MAPK) pathway, often activated through mutations in the V600 codon of BRAF (in 35–50% of melanomas) and the Q61 codon of NRAS (10–25%)2, with mutations being mutually exclusive.
Mutations of KIT are found in particular subsets of melanoma, where the mutations activate signal-transduction pathways (MAPK and PI3K) that ultimately lead to cell proliferation. Approximately 70% of KIT mutations identified in melanoma are found in exon 11, most commonly L576P (Figure 1).
Neurofibromatosis type 1 (NF1) is a relatively common tumour predisposition syndrome related to germline aberrations of NF1, a tumour suppressor gene. Recent studies have additionally shown NF1 to play a critical role in somatic events in a wide range of tumours, including melanoma. The tumour suppressor function of neurofibromin is largely attributed to a small central region which comprises 360 amino acids encoded by exons 20-27a3. OGT’s expert bait design offers excellent uniformity for all of these key genes associated with melanoma (Figure 2).

*The SureSeq FFPE DNA Repair Mix can only be purchased in conjunction with SureSeq NGS panels, not as a standalone product. †Due to the presence of pseudogenes in NF1, it is recommended that an orthogonal technique is used to verify any mutations detected.
