CYP26B1 and atrial fibrillation: Additionally, CYP26B1 and TUBA3D expression levels were significantly associated with NT-proBNP (β = 349, 95% CI 23.8-674, p= 0.036; β = -140, 95% CI -272 to -8.81, p = 0.038, respectively). We identified candidate genes potentially involved in LAAT in AF patients through RNA-seq analysis.
