Trait
Prolonged QRS complex
Increased time for the complex comprised of the Q wave, R wave, and S wave as measured by the electrocardiogram (EKG).. In adults, normal values are 0.06 - 0.10 sec.
Summary
- Also called

Changes in these genes cause rare conditions in which Prolonged QRS complex 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 |
|---|---|---|
| JUPjunction plakoglobin | Always | In 2 conditions |
| RNU6ATACRNA, U6atac small nuclear | Always | In 1 condition |
| PRKAG2protein kinase AMP-activated non-catalytic subunit gamma 2 | Very often (80–99%) | In 3 conditions |
| GJA5gap junction protein alpha 5 | Often (30–79%) | In 1 condition |
| IRX5iroquois homeobox 5 | Often (30–79%) | In 1 condition |
| PKP2plakophilin 2 | Often (30–79%) | In 1 condition |
| ALPK3alpha kinase 3 | Sometimes (5–29%) | In 1 condition |
| TMEM43transmembrane protein 43 | 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.
