Description
A "risk genotype" for atrial fibrillation (AF) refers to a specific genetic variant, usually identified within genes like KCNQ1, SCN5A, PITX2, or the 4q25 locus, which is associated with an increased likelihood of developing atrial fibrillation due to its influence on cardiac electrical signaling pathways; essentially, individuals carrying these variants are considered at higher risk for developing AF compared to the general population.
This test is for "4q25" only
