Changes in these genes cause rare conditions in which Large 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 |
|---|---|---|
| DLK1delta like non-canonical Notch ligand 1 | Very often (80–99%) | In 3 conditions |
| MEG3maternally expressed 3 | Very often (80–99%) | In 3 conditions |
| RTL1retrotransposon Gag like 1 | Very often (80–99%) | In 3 conditions |
| LBRlamin B receptor | Often (30–79%) | In 1 condition |
| LMNAlamin A/C | Sometimes (5–29%) | In 1 condition |
| ZMPSTE24zinc metallopeptidase STE24 | Sometimes (5–29%) | In 1 condition |
| MKS1MKS transition zone complex subunit 1 | Not recorded | In 1 condition |
| SKIC3SKI3 subunit of superkiller complex | 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.
