Chapter 6 - Unraveling the Root Cause
At 3:30 PM, thirty minutes before the dreaded CPS safety review, the genetics department called Dr. Chen’s cell phone with an emergency update.
“Maya, we rushed the preliminary blood panel for Claire and Eli,” the head geneticist reported over the speakerphone. “We found a rare, heterozygous mutation in the SCN5A gene.”
Dr. Vance gasped. “SCN5A? The sodium channel gene?”
“Precisely,” the geneticist replied. “It’s a specific variant known as a dual-phenotype cardiac-neurological sodium channelopathy. In adults, it can cause benign temporal lobe excitability that only manifests under severe metabolic stress or sleep deprivation. In infants, it causes benign, self-limiting neonatal cardiac micro-arrhythmias that typically resolve on their own as the heart’s conduction system matures around six months of age.”
“Is it treatable?” Daniel asked eagerly, his heart pounding.
“Extremely treatable,” Dr. Vance answered with a huge smile. “A low dose of a oral sodium channel blocker—like Flecainide or Beta-blockers for Eli, and a specialized anti-seizure medication like Oxcarbazepine for Claire—will completely stabilize the electrical pathways in both of their bodies!”

“And it’s completely reversible?” Claire asked, her voice trembling with hope as her awareness fully returned from her earlier episode.
“Yes!” Dr. Chen said, taking Claire’s hands. “This proves beyond a shadow of a doubt that you were never suffering from postpartum psychosis, you were never delusional, and you were never a danger to your child. You are a mother whose body and baby were sharing a temporary, treatable genetic electrical glitch—and your motherly instinct was so sharp that you felt what no medical equipment picked up until today!”
