Changes in these genes cause rare conditions in which Severe sun sensitivity 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 |
|---|---|---|
| GATA1GATA binding protein 1 | Very often (80–99%) | In 1 condition |
| URODuroporphyrinogen decarboxylase | Very often (80–99%) | In 1 condition |
| UROSuroporphyrinogen III synthase | Very often (80–99%) | In 1 condition |
| EPM2AEPM2A glucan phosphatase, laforin | Sometimes (5–29%) | In 1 condition |
| NHLRC1NHL repeat containing E3 ubiquitin protein ligase 1 | Sometimes (5–29%) | In 1 condition |
| DHCR77-dehydrocholesterol reductase | 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.
