6 genes linked to Atrial arrhythmia

Changes in these genes cause rare conditions in which Atrial arrhythmia 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
TTRtransthyretin	Very often (80–99%)	In 1 condition
LAMP2lysosome associated membrane protein 2	Often (30–79%)	In 1 condition
CITED2Cbp/p300 interacting transactivator with ED-rich tail 2	Sometimes (5–29%)	In 1 condition
EMDemerin	Not recorded	In 1 condition
NPPAnatriuretic peptide A	Not recorded	In 1 condition
TNNI3KTNNI3 interacting kinase	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.
