Trait
Ectopic accessory finger-like appendage
In contrast to forms of polydactyly where the supernumerary digit (this can either be a rudimentary or a completely 'normal' digit) is either located postaxial (on the ulnar side of the hand, next to the little finger), preaxial (on the radial side of the hand, next to the thumb) or mesoaxial (somewhere central, between thumb and little finger), a supernumerary digit may also be placed ectopically, meaning anywhere else except post-,meso- or preaxial. In the literature this is sometimes referred to as Disorganisation-like Syndrome (OMIM223200).

Changes in these genes cause rare conditions in which Ectopic accessory finger-like appendage 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 |
|---|---|---|
| DDX59DEAD-box helicase 59 | 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.
