In white male proband who was diagnosed with paroxysmal lone atrial fibrillation (ATFB10; 614022) at 39 years of age, Darbar et al. (2008) identified heterozygosity for a G-to-C transversion in the SCN5A gene, resulting in a his445-to-asp (H445D) substitution at a highly conserved residue that was predicted to perturb cardiac sodium channel function. The proband had left atrial enlargement and an ejection fraction of 60% by transthoracic echocardiography. The mutation was also detected in his affected father and brother, but was not found in an unaffected sister or in 720 control alleles.
