Rs3740066

rs3740066, a SNP in the ABCC2 gene, is reported to be associated with a higher risk of developing intrahepatic cholestasis of pregnancy (ICP) based on a study of ~70 Argentinian patients. ICP is associated with increased fetal risks such as premature birth or intrauterine death.

The risk allele is rs3740066(A), and the odds ratio for homozygous rs3740066(A;A) mothers is 4.44 (CI: 1.83 - 10.78), and for heterozygous mothers 1.65 (CI: 0.76 - 3.64), compared to rs3740066(G;G) mothers.
