Changes in these genes cause rare conditions in which Abnormality of head shape 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 |
|---|---|---|
| PEX19peroxisomal biogenesis factor 19 | Always | In 1 condition |
| AKT3AKT serine/threonine kinase 3 | Often (30–79%) | In 1 condition |
| MTORmechanistic target of rapamycin kinase | Often (30–79%) | In 1 condition |
| PIK3CAphosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha | Often (30–79%) | In 1 condition |
| POLR3ARNA polymerase III subunit A | Often (30–79%) | In 1 condition |
| PTCH1patched 1 | Sometimes (5–29%) | In 1 condition |
| RNF135ring finger protein 135 | Sometimes (5–29%) | In 1 condition |
| HRASHRas proto-oncogene, GTPase | Not recorded | In 1 condition |
| KRASKRas proto-oncogene, GTPase | Not recorded | In 1 condition |
| NRASNRAS proto-oncogene, GTPase | 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.
