Changes in these genes cause rare conditions in which Long thumb 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 |
|---|---|---|
| PTH1Rparathyroid hormone 1 receptor | Always | In 1 condition |
| RECQLRecQ like helicase | Always | In 1 condition |
| KAT6Blysine acetyltransferase 6B | Often (30–79%) | In 1 condition |
| KCNN3potassium calcium-activated channel subfamily N member 3 | Often (30–79%) | In 1 condition |
| TBC1D24TBC1 domain family member 24 | Often (30–79%) | In 1 condition |
| ADH5alcohol dehydrogenase 5 (class III), chi polypeptide | Sometimes (5–29%) | In 1 condition |
| MED12mediator complex subunit 12 | Sometimes (5–29%) | In 1 condition |
| NPR3natriuretic peptide receptor 3 | 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.
