Changes in these genes cause rare conditions in which Blue yellow color blindness 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 |
|---|---|---|
| RBP4retinol binding protein 4 | Always | In 1 condition |
| GUCY2Dguanylate cyclase 2D, retinal | Often (30–79%) | In 1 condition |
| OPN1SWopsin 1, short wave sensitive | Often (30–79%) | In 2 conditions |
| POC1BPOC1 centriolar protein B | Often (30–79%) | In 1 condition |
| C1QTNF5C1q and TNF related 5 | Sometimes (5–29%) | In 1 condition |
| OPA3outer mitochondrial membrane lipid metabolism regulator OPA3 | Sometimes (5–29%) | In 1 condition |
| DNM1Ldynamin 1L | Not recorded | In 1 condition |
| NR2E3nuclear receptor subfamily 2 group E member 3 | Not recorded | In 1 condition |
| OPA1OPA1 mitochondrial dynamin like GTPase | Not recorded | In 2 conditions |
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.
