Changes in these genes cause rare conditions in which Atrial standstill 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 |
|---|---|---|
| EMDemerin | Always | In 1 condition |
| GJA5gap junction protein alpha 5 | Always | In 1 condition |
| NPPAnatriuretic peptide A | Very often (80–99%) | In 2 conditions |
| SCN5Asodium voltage-gated channel alpha subunit 5 | Very often (80–99%) | In 2 conditions |
| CASQ2calsequestrin 2 | Often (30–79%) | In 1 condition |
| RYR2ryanodine receptor 2 | Often (30–79%) | In 1 condition |
| TRDNtriadin | Often (30–79%) | 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.
