CACNA1C and cardiac arrhythmia: The top association findings suggested that the BD risk alleles at SNP rs4765913 in CACNA1C gene and rs7042161 in SVEP1 may be associated with increased risk of ‘cardiac dysrhythmias' (odds ratio (OR)=1.1, P=3.4 × 10−3) and ‘essential hypertension' (OR=1.1, P=3.5 × 10−3), respectively.
