Iron Deficiency Anemia Risk: What Your DNA Says
Genetic variants affecting iron absorption, transport, and storage influence anemia susceptibility.
Iron Deficiency Anemia Risk is a physical characteristic shaped by many genes of small effect rather than a single switch. Twin and family studies show that most physical traits are substantially heritable, yet no individual variant determines the outcome on its own — your result reflects how your particular combination of alleles compares with the reference population.
Key Genes Behind Iron Deficiency Anemia Risk
Scientists have identified specific genetic variants that influence iron deficiency anemia risk. While most traits are shaped by a combination of multiple genes and environmental factors, the following genes play particularly important roles:
TMPRSS6TFRCSLC11A2TMPRSS6TMPRSS6 regulates hepcidin, the master iron hormone; variants are among the strongest common influences on iron status.
TFRCTFRC has been associated with iron deficiency anemia risk in genetic studies; as with most common variants, its individual effect is modest and works alongside many other genetic and non-genetic factors.
SLC11A2SLC11A2 has been associated with iron deficiency anemia risk in genetic studies; as with most common variants, its individual effect is modest and works alongside many other genetic and non-genetic factors.
How Genetics Influence Iron Deficiency Anemia Risk
Your DNA contains instructions that shape iron deficiency anemia risk through variations in protein structure, enzyme activity, and gene expression levels. Small differences in your genetic code, known as single nucleotide polymorphisms (SNPs), can alter how your body develops and functions in ways that affect this trait.
For iron deficiency anemia risk, the interplay between genetic variants and environmental factors like diet, lifestyle, and exposure history determines your individual outcome. Some people carry variants that strongly push toward one expression of the trait, while others have a more balanced genetic profile where environment plays a larger role.
Genetic analysis provides insight into your predispositions, but does not guarantee a specific outcome. Traits are complex, and your unique combination of genetics and life experience shapes who you are.

For each relevant SNP, GenomeInsight reports your genotype, the trait-associated alleles, published research findings, and how your genetic profile compares to the general population. Results are presented with clear visualizations and easy-to-understand explanations.
Frequently Asked Questions About Iron Deficiency Anemia Risk
Which genes influence iron deficiency anemia risk?
The variants most associated with iron deficiency anemia risk lie in or near TMPRSS6, TFRC, SLC11A2. Each contributes a small effect, and your result reflects the combined picture across these markers plus the ancestry-matched reference frequencies in your raw data file.
Is iron deficiency anemia risk purely genetic?
No. Genetics contributes a measurable share of the variation in physical traits traits, but environment, lifestyle and chance do the rest. A predisposition is a statistical nudge, not a verdict — use it as a starting point for observation, not a fixed outcome.
What DNA data do I need for this result?
Any standard raw-data file from 23andMe, AncestryDNA, MyHeritage or similar genotyping services contains the relevant markers. Upload the file and this result — together with 30 free traits — is computed locally in your browser; your file never leaves your device.
