Changes in these genes cause rare conditions in which Achromatopsia 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 |
|---|---|---|
| ATF6activating transcription factor 6 | Very often (80–99%) | In 1 condition |
| CNGA3cyclic nucleotide gated channel subunit alpha 3 | Very often (80–99%) | In 1 condition |
| CNGB3cyclic nucleotide gated channel subunit beta 3 | Often (30–79%) | In 1 condition |
| GNAT2G protein subunit alpha transducin 2 | Not recorded | In 1 condition |
| NBASNBAS subunit of NRZ tethering complex | Not recorded | 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.
