Zinc is essential for erythropoiesis, yet the mechanisms linking zinc availability to heme biosynthesis and anemia risk remain unclear. This study aimed to define zinc-responsive pathways in differentiating erythroid progenitors and to evaluate the translational relevance of\n                    <jats:italic toggle=\"yes\">SLC39A10<\/jats:italic>\n                    (\n                    <jats:italic toggle=\"yes\">ZIP10<\/jats:italic>\n                    ) genetic variants to hematological health. To elucidate the molecular basis of zinc\u2019s role in erythropoiesis, we performed transcriptomic profiling of zinc-restricted G1E-ER4 cells during differentiation and compared it to iron chelation and \u03b4-aminolevulinic acid dehydratase inhibition. Zinc deficiency uniquely enriched genes involved in not only heme biosynthesis but cellular maintenance functions. Zinc restriction caused a marked suppression of\n                    <jats:italic toggle=\"yes\">Alad<\/jats:italic>\n                    transcript abundance, impairing the first enzymatic step of cytosolic heme biosynthesis. Notably,\n                    <jats:italic toggle=\"yes\">Slc39a10<\/jats:italic>\n                    (\n                    <jats:italic toggle=\"yes\">Zip10<\/jats:italic>\n                    ) was the only zinc transporter strongly induced by zinc deficiency, independent of iron status. Loss of ZIP10 exacerbated zinc depletion, further reduced\n                    <jats:italic toggle=\"yes\">Alad<\/jats:italic>\n                    expression, and diminished heme output, highlighting its role as a compensatory importer during zinc scarcity. GWAS database analyses revealed that\n                    <jats:italic toggle=\"yes\">SLC39A10<\/jats:italic>\n                    variants are significantly associated with hemoglobin concentration, hematocrit, and iron deficiency anemia risk. Together, ZIP10 safeguards erythroid zinc homeostasis and heme synthesis under limiting zinc conditions.
