Conflicting data exists on Tp53 codon 72 polymorphisms in non-melanocytic skin carcinomas (NMSCs): while some studies suggested that Tp53-72R is a risk factor for developing cutaneous SCC in immunosuppressed patients with epidermodysplasia verruciformis (EV) [51] or in post-transplant individuals [52], [53], [54], others did not [55], [56], [57], [58]. The gene discussed is TP53; the disease is epidermodysplasia verruciformis.
