Changes in these genes cause rare conditions in which Decreased size of facial bones 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 |
|---|---|---|
| POLR3ARNA polymerase III subunit A | Very often (80–99%) | In 1 condition |
| LMNAlamin A/C | Often (30–79%) | In 1 condition |
| CEP120centrosomal protein 120 | Not recorded | In 1 condition |
| DYMdymeclin | Not recorded | In 2 conditions |
| FIG4FIG4 phosphoinositide 5-phosphatase | Not recorded | In 1 condition |
