|(-;CTTACT)||1.1||Slightly decreased risk (0.9x) of certain cancers|
It has been linked to higher risk for multiple tumours including colorectal cancer (CRC) in Chinese populations; however, it showed no association with colorectal cancer risk in a study of 4,000 UK cases.[PMID 18362937]
A 2012 meta-analysis found a small protective effect (i.e. slightly reduced cancer risk) associated with the rs3834129(-;CTTACT) "6N ins/del" genotype compared to the more common "6N/6N" (rs3834129(CTTACT;CTTACT)) genotype, however, there was no statistical effect noted for the "6N del/del" genotype.[PMID 23170140]
