Atrial fibrillation, familial, 7(ATFB7)

MedGen UID:
393658
Concept ID:
C2677106
Disease or Syndrome
Synonyms: ATFB7; KCNA5-Related Familial Atrial Fibrillation
 
Gene (location): KCNA5 (12p13.32)
 
Monarch Initiative: MONDO:0012828
OMIM®: 612240

Definition

Atrial fibrillation (AF) is the most common sustained cardiac rhythm disturbance, affecting more than 2 million Americans, with an overall prevalence of 0.89%. The prevalence increases rapidly with age, to 2.3% between the ages of 40 and 60 years, and to 5.9% over the age of 65. The most dreaded complication is thromboembolic stroke (Brugada et al., 1997). For a discussion of genetic heterogeneity of atrial fibrillation, see 608583. [from OMIM]

Additional description

From MedlinePlus Genetics
Familial atrial fibrillation is an inherited abnormality of the heart's normal rhythm. Atrial fibrillation is characterized by episodes of uncoordinated electrical activity (fibrillation) in the heart's upper chambers (the atria), which cause a fast and irregular heartbeat. If untreated, this abnormal heart rhythm (arrhythmia) can lead to dizziness, chest pain, a sensation of fluttering or pounding in the chest (palpitations), shortness of breath, or fainting (syncope). Atrial fibrillation also increases the risk of stroke and sudden death. Complications of atrial fibrillation can occur at any age, although some people with this heart condition never experience any health problems associated with the disorder.  https://medlineplus.gov/genetics/condition/familial-atrial-fibrillation

Clinical features

From HPO
Palpitations
MedGen UID:
14579
Concept ID:
C0030252
Finding
A sensation that the heart is pounding or racing, which is a non-specific sign but may be a manifestation of arrhythmia.
Premature atrial contractions
MedGen UID:
19455
Concept ID:
C0033036
Disease or Syndrome
A type of cardiac arrhythmia with premature atrial contractions or beats caused by signals originating from ectopic atrial sites.
Sinus bradycardia
MedGen UID:
39316
Concept ID:
C0085610
Pathologic Function
Bradycardia related to a mean resting sinus rate of less than 50 beats per minute.
Paroxysmal atrial fibrillation
MedGen UID:
115990
Concept ID:
C0235480
Disease or Syndrome
Episodes of atrial fibrillation that typically last for several hours up to one day and terminate spontaneously.
Prolonged PR interval
MedGen UID:
154645
Concept ID:
C0600125
Finding
Increased time for the PR interval (beginning of the P wave to the beginning of the QRS complex).
Prolonged QTc interval
MedGen UID:
294666
Concept ID:
C1560305
Pathologic Function
A longer than normal interval (corrected for heart rate) between the Q and T waves in the heart's cycle. Prolonged QTc can cause premature action potentials during late phase depolarizations thereby leading to ventricular arrhythmias and ventricular fibrillations.
Permanent atrial fibrillation
MedGen UID:
750308
Concept ID:
C2586056
Pathologic Function
Atrial fibrillation (AF) that cannot be successfully terminated by cardioversion, and longstanding (more than 1 year) AF, where cardioversion is not indicated or has not been attempted, is termed permanent.
