KIT and malignant conjunctival melanoma: TERT promoter mutations were identified in 32–41% of conjunctival melanomas.29, 30 One study reported a KIT mutation in 1/14 (7%) tumours.31 Copy number analysis identified alterations reminiscent of cutaneous and mucosal melanomas, including CDKN2A and PTEN losses.28 These data suggest that conjunctival melanomas are genetically similar to cutaneous melanomas, but aside from BRAF, NRAS and TERT promoter mutations, recurrent mutations in other genes have not been identified.
