Changes in these genes cause rare conditions in which Skin-picking 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 |
|---|---|---|
| KDM2Blysine demethylase 2B | Always | In 1 condition |
| HDAC4histone deacetylase 4 | Often (30–79%) | In 1 condition |
| MAGEL2MAGE family member L2 | Often (30–79%) | In 5 conditions |
| NDNnecdin, MAGE family member | Often (30–79%) | In 3 conditions |
| OCA2OCA2 melanosomal transmembrane protein | Often (30–79%) | In 3 conditions |
| SIM1SIM bHLH transcription factor 1 | Often (30–79%) | In 1 condition |
| SNRPNsmall nuclear ribonucleoprotein polypeptide N | Often (30–79%) | In 4 conditions |
| CHD5chromodomain helicase DNA binding protein 5 | Sometimes (5–29%) | In 1 condition |
| CNTNAP2contactin associated protein 2 | Sometimes (5–29%) | 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.
