Changes in these genes cause rare conditions in which Increased arm span 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 |
|---|---|---|
| TAF4TATA-box binding protein associated factor 4 | Always | In 1 condition |
| APC2APC regulator of Wnt signaling pathway 2 | Very often (80–99%) | In 1 condition |
| NSD1nuclear receptor binding SET domain protein 1 | Very often (80–99%) | In 1 condition |
| TRAPPC2trafficking protein particle complex subunit 2 | Very often (80–99%) | In 1 condition |
| DLG4discs large MAGUK scaffold protein 4 | Often (30–79%) | In 1 condition |
| EMILIN1elastin microfibril interfacer 1 | Often (30–79%) | In 1 condition |
| FBN1fibrillin 1 | Often (30–79%) | In 1 condition |
| TGFB3transforming growth factor beta 3 | 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.
