The C allele is associated with:
- C= increased activity
- The risk allele ‘C’ of the SNP rs9282861 or G638A in the SULT1A1 gene is associated with a poor response to tamoxifen, a chemotherapeutic drug used to treat breast cancer. It is thought that SULT1A1 activity is increased in those carrying the ‘C’ allele meaning that tamoxifen is targeted for degradation more rapidly. Although conflicting studies have shown no effect
The fact that the C allele of SULT1A1 leads to increased activity may explain the findings of several other studies which described elevated gastrointestinal cancer risk in those carrying the ‘C’ allele who consumed a diet rich in raw red meat.
