Impact of codon 72 Arg > Pro single nucleotide polymorphism in TP53 gene in the risk of kangri cancer: a case control study in Kashmir.

Kangri cancer found only in Kashmir (north India) is a unique thermally induced squamous cell carcinoma of the skin that develops because of chronic and persistent irritation due to the use of a kangri (a brazier) by the Kashmiri people to combat the chilling cold temperature during winter. Being unique to this region, the molecular etiology of the invasive kangri cancer is not known fully. The TP53 gene, codon 72 polymorphism (Arg72Pro), has been found to be associated with cancer susceptibility but has not been investigated in kangri cancer risk.
