Conversely, while we found that gabapentin, levetiracetam, and pregabalin had no effects on Nav1.5 currents, Eroglu et al. found that pregabalin conferred higher SCD risk than valproic acid, while gabapentin and levetiracetam also tended to have higher SCD risk (but it was not statistically significantly). This evidence concerns the gene SCN5A and Schnyder corneal dystrophy.
