Survey of allelic expression using EST mining. A genetic association analysis of cognitive ability and cognitive ageing using 325 markers for 109 genes associated with oxidative stress or cognition. A novel association between a SNP in CYBRD1 and serum ferritin levels in a cohort study of HFE hereditary haemochromatosis. potential markers of iron deficiency anaemia risk: two in the transferrin gene TF (rs3811647, rs1799852) and two in the HFE gene (C282Y, H63D), explain 35% of the genetic variation or heritability of serum transferrin in menstruating women. The minor allele of rs3811647 was associated with higher serum transferrin levels and lower transferrin saturation, while the minor alleles of rs1799852 and the C282Y and H63D mutations of HFE were associated with lower serum transferrin levels. http://www.nutritionandmetabolism.com/content/8/1/69 serum transferrin: Two SNPs on TF gene, rs1799852 (MAF 0.09), and rs2280673 (MAF 0.34), which were independently influencing variation in serum transferrin (nominal p = 4.7 × 10−6 and 2.3 × 10−4, respectively). rs1799852 and rs2280673 were also associated with serum ferritin (p = 0.04 and 0.003) but not with serum iron or transferrin saturation.
