Interestingly, we also observed a strong association between LMOD2 and DCM under a dominant model (OR = 13.7 (5.4–35.2) for rare PTVs; PCauchy = 7.8 × 10−4, FDR QCauchy = 0.028; Supplementary Tables 7 and 8), as well as nominal associations with HF and AF (PCauchy < 0.05). This evidence concerns the gene LMOD2 and atrial fibrillation.
