CALM1
Associated conditions:
- Arrhythmia
CALM1 makes calmodulin, a calcium-sensing protein that fine-tunes the electrical signals controlling each heartbeat. Genetic changes in this gene are associated with an autosomal dominant risk of dangerous rhythm disorders such as Catecholaminergic polymorphic ventricular tachycardia (CPVT) or long QT syndrome, which may trigger fainting or cardiac arrest at a young age. Knowing your genetic status enables protective medication and activity guidance.
Conditions linked to CALM1
Arrhythmia
An arrhythmia is an abnormal heart rhythm. Inherited forms can cause fast, irregular or dangerous rhythms and, rarely, sudden collapse, so carriers benefit from heart-rhythm testing, sometimes medication, and avoiding specific triggers.
