Therefore, this study aims to investigate whether minor alleles of the TMPRSS6 gene at rs855791 and rs4820268 as well as the usual iron intake are associated with low iron and hemoglobin concentrations among under-two-year-old children in East Lombok, where the prevalence of anemia and iron deficiency was reported to be high. This evidence concerns the gene TMPRSS6 and anemia (phenotype).
