[[rs520354]] is a SNP in an intron of the apolipoprotein B [[APOB]] gene; it is also known as the IVS6+360C>T variant.

In a study of ~1,000 Chinese patients with various biliary tract conditions, including cancer and gallstones, men carrying a [[rs520354]](A) allele had a 2x risk of [[bile duct cancer]] (CI: 1.2-3.4).{{PMID|18296645|OA=1
