Changes in these genes cause rare conditions in which Mesoaxial polydactyly 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 |
|---|---|---|
| GLI3GLI family zinc finger 3 | Often (30–79%) | In 1 condition |
| LZTFL1leucine zipper transcription factor like 1 | Often (30–79%) | In 1 condition |
| CPLANE1ciliogenesis and planar polarity effector complex subunit 1 | 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.
