Changes in these genes cause rare conditions in which Multiple exostoses 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 |
|---|---|---|
| EXT1exostosin glycosyltransferase 1 | Always | In 1 condition |
| EXT2exostosin glycosyltransferase 2 | Always | In 1 condition |
| PTPN11protein tyrosine phosphatase non-receptor type 11 | Always | In 1 condition |
| ALX4ALX homeobox 4 | Rarely (1–4%) | In 1 condition |
| MSX2msh homeobox 2 | Rarely (1–4%) | In 1 condition |
| SHOXSHOX homeobox | 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.
