The examined genes and single-nucleotide polymorphisms were 1) TMPRSS6, involved in regulation of hepcidin: rs855791; 2) HFE, associated with hemochromatosis: rs1800562 and rs1799945; 3) BTBD9, associated with restless leg syndrome: rs9357271; and 4) TF, encoding transferrin: rs2280673 and rs1830084.
Matriptase-2 emerges as an attractive target for the treatment of conditions associated with iron overload, such as hemochromatosis or beta-thalassemia.
Using a multi-ethnic sample of cases and controls from Houston, TX, we examined two HFE variants (rs1800562 and rs1799945), one transferrin receptor gene (TFRC) variant (rs3817672) and three additional iron regulatory gene (IRG) variants (SLC11A2 rs422982; TMPRSS6rs855791 and rs733655) for their associations with childhood ALL.
As part of the Healthy Ageing across the Life Course (HALCyon) program, men and women aged between 44 and 90 y from 6 UK cohorts were genotyped for polymorphisms associated with circulating concentrations of iron [rs4820268transmembrane protease, serine 6 (TMPRSS6) and rs1800562hemochromatosis (HFE)], vitamin B-12 [(rs492602 fucosyltransferase 2 (FUT2)], vitamin D ([rs2282679 group-specific component (GC)] and β-carotene ([rs6564851 beta-carotene 15,15'-monooxygenase 1 (BCMO1)].
