1 Abbreviations: CS: case subject(s) with very low vitamin A status; CGAS: candidate gene association study; GWAS: genome-wide association study; MAF: minor allele frequency, retrieved from the SNP database in PubMed (https://www.ncbi.nlm.nih.gov/pubmed?cmd=search); the gene official symbols are those found in PubMed and approved by the Hugo Gene Nomenclature Committee (available online: http://www.genenames.org/). FB-βC: fasting blood β-carotene concentration; FB-βCrypt/αC: fasting blood β-cryptoxanthin or α-carotene; FB-RET: fasting blood retinol concentration; βC-B: β-carotene bioavailability. 2 In this study, β-carotene bioavailability was estimated by measuring the postprandial chylomicron β-carotene response (0–8 h area under the curve) to a β-carotene containing test-meal. * These SNPs were associated with the variability of β-carotene bioavailability, but this association was likely due to their involvement in the postprandial metabolism of chylomicrons [91,113], which are the lipoparticles that carry newly-absorbed β-carotene from the intestine to the liver.
