Changes in these genes cause rare conditions in which Hypochromia is seen. Most people with this trait have none of those conditions, and a gene on this list says nothing about anyone's own genome.
| Gene | How often it is seen | Conditions |
|---|---|---|
| KLF1KLF transcription factor 1 | Always | In 1 condition |
| SLC11A2solute carrier family 11 member 2 | Always | In 1 condition |
| STEAP3STEAP3 metalloreductase | Always | In 1 condition |
| HBBhemoglobin subunit beta | Very often (80–99%) | In 1 condition |
| KCNN4potassium calcium-activated channel subfamily N member 4 | Often (30–79%) | In 1 condition |
| PIEZO1piezo type mechanosensitive ion channel component 1 (Er blood group) | Often (30–79%) | In 1 condition |
| RHAGRh associated glycoprotein | Often (30–79%) | In 1 condition |
| RHCERh blood group CcEe antigens | Often (30–79%) | In 1 condition |
| RHDRh blood group D antigen | Often (30–79%) | In 1 condition |
| SLC4A1solute carrier family 4 member 1 (Diego blood group) | Often (30–79%) | In 1 condition |

How often is among people with one of the gene's conditions, the most often across them, as the Human Phenotype Ontology records it. These pages describe traits and the research behind them; they are not a diagnosis, and a doctor or genetic counsellor is the person to ask about symptoms.
