p53 codon 72 Arg homozygotes are associated with an increased risk of cutaneous melanoma.


The p53 gene plays an important role in cell cycle control, facilitating DNA repair activities in response to DNA damage. Aberrant cell cycle control impairs DNA repair and increases the probability of mutations that can lead to carcinogenesis. The p53 gene is polymorphic at codon 72 (Arg/Pro) of its protein, which is functionally distinct, leading to… (More)
