Changes in these genes cause rare conditions in which Abnormal hemoglobin 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 |
|---|---|---|
| EPORerythropoietin receptor | Very often (80–99%) | In 1 condition |
| GATA1GATA binding protein 1 | Very often (80–99%) | In 1 condition |
| HBA1hemoglobin subunit alpha 1 | Very often (80–99%) | In 1 condition |
| HBA2hemoglobin subunit alpha 2 | Very often (80–99%) | In 1 condition |
| HBBhemoglobin subunit beta | Very often (80–99%) | In 4 conditions |
| HBDhemoglobin subunit delta | Very often (80–99%) | In 1 condition |
| HBG1hemoglobin subunit gamma 1 | Very often (80–99%) | In 1 condition |
| ATRXATRX chromatin remodeler | 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.
