Trait
Shortened PR interval
Reduced time for the PR interval (beginning of the P wave to the beginning of the QRS complex). In adults, normal values are 120 to 200 ms long.
Summary
- Also called
- Electrocardiographic short PR interval, Short P-R interval, Shortened PR interval on EKG

Changes in these genes cause rare conditions in which Shortened PR interval 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 |
|---|---|---|
| PRKAG2protein kinase AMP-activated non-catalytic subunit gamma 2 | Always | In 3 conditions |
| GAAalpha glucosidase | Often (30–79%) | In 2 conditions |
| MTFMTmitochondrial methionyl-tRNA formyltransferase | Often (30–79%) | In 1 condition |
| ALPK3alpha kinase 3 | Sometimes (5–29%) | In 1 condition |
| CACNA1Scalcium voltage-gated channel subunit alpha1 S | Sometimes (5–29%) | In 1 condition |
| DOHHdeoxyhypusine hydroxylase | Sometimes (5–29%) | In 1 condition |
| GABRA3gamma-aminobutyric acid type A receptor subunit alpha3 | Sometimes (5–29%) | In 1 condition |
| KCNJ18potassium inwardly rectifying channel subfamily J member 18 | Sometimes (5–29%) | In 1 condition |
| MT-CYBmitochondrially encoded cytochrome b | Rarely (1–4%) | In 1 condition |
| TRPM4transient receptor potential cation channel subfamily M member 4 | 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.
