is an insertion/deletion SNP in the DNA repair XRCC4
Individuals in a Taiwanese Chinese population heterozygous for this SNP rs28360071 were at increased risk (odd ratio 1.57, CI: 1.12-2.21) of oral cancer compared to those homozygous for the insertion form of this SNP. The deletion allele was also associated with 3x higher risk than the insertion allele among smokers and betel quid chewer groups.[PMID 18164646]
