Impact of selected genetic polymorphisms on fatty acid absorption. Complete genotype data for the indicated single nucleotide polymorphism was available for 42 subjects. For each fatty acid, bars indicate the difference ± SD in mean percent absorption between subjects homozygous for the common allele and subjects carrying one or two copies of the variant allele. Thus, positive values indicate that carriers of a variant allele absorbed that fatty acid less efficiently than subjects homozygous for the common allele; negative values indicate that variant allele carriers absorbed that fatty acid more efficiently. Open bars indicate that the difference between genotype groups was significant at P < 0.05; all other differences were not statistically significant. APO, apolipoprotein; FABP2, fatty acid-binding protein-2; MTTP, microsomal triglyceride transfer protein.
