Changes in these genes cause rare conditions in which Palmar hyperlinearity 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 |
|---|---|---|
| ALOX12Barachidonate 12-lipoxygenase, 12R type | Always | In 1 condition |
| ALOXE3arachidonate epidermal lipoxygenase 3 | Always | In 2 conditions |
| CERS3ceramide synthase 3 | Always | In 1 condition |
| CYP4F22cytochrome P450 family 4 subfamily F member 22 | Always | In 1 condition |
| KDF1keratinocyte differentiation factor 1 | Always | In 1 condition |
| STSsteroid sulfatase | Sometimes (5–29%) | In 1 condition |
| FLGfilaggrin | 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.
