Changes in these genes cause rare conditions in which Small placenta 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 |
|---|---|---|
| LMNAlamin A/C | Very often (80–99%) | In 1 condition |
| ZMPSTE24zinc metallopeptidase STE24 | Very often (80–99%) | In 1 condition |
| IGF1insulin like growth factor 1 | Often (30–79%) | In 1 condition |
| CDKN1Ccyclin dependent kinase inhibitor 1C | Sometimes (5–29%) | In 1 condition |
| HMGA2high mobility group AT-hook 2 | Sometimes (5–29%) | In 1 condition |
| IGF2insulin like growth factor 2 | Sometimes (5–29%) | In 1 condition |
| PLAG1PLAG1 zinc finger | Sometimes (5–29%) | In 1 condition |
| MUSKmuscle associated receptor tyrosine kinase | Not recorded | In 1 condition |
| PHGDHphosphoglycerate dehydrogenase | 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.
