WebAbstract Germline CDKN2A mutations occur in 40 % of 3-or-more case melanoma families while mutations of CDK4, BAP1, and genes involved in telomere function (ACD, TERF2IP, POT1), have also been implicated in melanomagenesis. Mutation of the promoter of the telom-erase reverse transcriptase (TERT) gene (c.-57 T[G variant) has been reported in … WebPOT1 is associated with the telomere shelterin complex that regulates telomere protection and telomerase access. Germline mutations in POT1 were recently shown to be associated with hereditary predisposition to melanoma. Our findings support a role of POT1 germline mutations in cancer predisposition beyond melanoma development, suggesting a ...

WebHowever, over the past decade, there is increasing evidence to show that extremely long telomeres caused by mutations in shelterin components (POT1, TPP1, and RAP1) also display an increased risk of cancer.
