Chapter 49 The Unexpected Finding
The text from Dr. Harris arrived at 9:47 PM. Damian read it twice, then handed me the phone. His hand was trembling. "Leo. They found something in his genetic data."
I stared at the screen. "But he was negative for everything. The GNB2, the MTHFR, the PAI-1. All of it."
"Apparently not."
We sat in the dark living room, the weight of another unknown pressing down. Leo was asleep upstairs, the only child who had been spared the daily medications and weekly appointments. Until now.
Damian called Dr. Harris. She answered on the first ring.
"I'm sorry to deliver news this late," she said. "The research team found a variant in Leo's file. It's a gene called SCN5A. It affects the heart's electrical system. Certain variants can cause irregular heart rhythms, especially during exercise or stress."
Damian's voice was tight. "Is Leo at risk right now?"
"The variant they found is what we call a variant of uncertain significance. It may never cause any problems. But it could. We need to do more testing to understand what we're dealing with."
Damian stood up and walked to the window. "What kind of testing?"
"An echocardiogram, an EKG, and a Holter monitor for twenty-four hours. We'll also want to test you and Ava for the same variant to see if it was inherited."
I wrote down the instructions on a notepad. "When can we do this?"
"I've already sent orders to the cardiology department. They can see Leo tomorrow morning at nine."
We did not tell Leo that night. He was sleeping, his face peaceful, his stuffed dinosaur tucked under his arm. I watched him from the doorway, my heart heavy with a new kind of fear.
Damian stood behind me. "He's been the lucky one. No medicine, no restrictions, no doctor visits."
"Maybe he still is. The doctor said it might never cause problems."
"But it might. And now we have to watch him too."
I turned to him. "We'll do the tests. Get answers. Then decide what to do. One step at a time."
The cardiology department was on the third floor of the children's hospital, a bright space with fish tanks and colorful chairs. Leo walked ahead, holding Damian's hand. He was quiet, sensing the tension in our voices.
"Am I sick?" he asked as we waited in the reception area.
"No," Damian said, kneeling to his level. "The doctor just wants to look at your heart to make sure everything is working right. It's like a checkup, but for your heart."
Leo looked at his chest. "Is my heart broken?"
I knelt beside him. "No, sweetheart. Your heart is fine. We're just checking. Like when you go to the dentist."
The nurse called his name. Leo climbed onto the exam table. The technician placed stickers on his chest and attached wires.
Leo closed his eyes. "This feels weird."
"You're doing great. Just breathe normally."
The EKG took five minutes. The echocardiogram took thirty. Leo watched his own heart on the screen, a pulsing black and white image.
"That's my heart?"
"That's your heart."
"It looks like a blob. A wiggly blob."
The technician smiled. "A very healthy wiggly blob."
The Holter monitor was a small device attached to Leo's chest with more stickers. He had to wear it for twenty-four hours, recording every heartbeat while he went about his day.
Leo looked at the wires trailing from his shirt. "Can I still play outside?"
"You can do everything normally. Run, jump, play, eat. Just don't get it wet."
Leo nodded. "Can I still eat pizza for dinner?"
"Yes."
"Then it's okay."
He skipped out of the room, the monitor bouncing against his chest.
Damian and I were tested the next day. Blood draws, EKGs, and echocardiograms. The technician said our hearts looked normal on the scans. But the genetic results would take another week to confirm.
Leo wore his monitor to school. His teacher called to ask about the wires. I explained. She was kind, understanding, and promised to keep an eye on him during recess.
By the second day, Leo had forgotten the monitor was there. He ran, played, and ate pizza. His heart kept beating.
The results came back on a Friday afternoon. Dr. Harris called with Dr. Park on the line, both of them on speaker.
"We've reviewed all the data," Dr. Park said. "Leo's heart structure is completely normal. His EKG is normal. The Holter monitor showed no arrhythmias or irregular beats."
Damian exhaled, a long, slow breath. "So the variant is harmless?"
"We can't say harmless with absolute certainty. But we can say that at this time, it's not causing any problems. We'll repeat the tests in six months and again in a year."
I leaned against the counter. "What about Ava and me?"
Dr. Harris spoke up. "Neither of you carries the SCN5A variant. It appears to be a spontaneous mutation in Leo. It happened on its own."
Damian's voice was quiet. "So he's the only one in the family with this."
"Yes. And right now, he's perfectly healthy. No restrictions. No medicine. Just monitoring."
We told Leo that evening. He was building a tower with Max, blocks scattered across the living room floor.
"Leo, the doctor called," Damian said. "Your heart is healthy. Everything looks normal."
Leo looked up. "So I'm not sick?"
"You're not sick."
"Can I still wear the monitor? I liked the stickers."
Damian laughed, the tension breaking. "We'll find you some stickers."
Max handed Leo a dinosaur sticker from his collection. Leo put it on his shirt over his heart.
"Now I'm like Rose and Lily and Max," he said. "I have a thing too. A heart thing."
Damian knelt beside him. "You have a thing that isn't causing any problems. That's a good thing."
Leo nodded. "I'm still special."
"You're very special."
That night, we sat on the porch. The stars were bright. The marigolds swayed in the evening breeze.
"Leo has a spontaneous mutation," Damian said. "It didn't come from us. We couldn't have predicted it."
"It means we couldn't have prevented it either."
"But he's healthy. His heart is fine. The doctors will watch him, but he can live a normal life."
I took his hand. "For now is enough. For now is all any of us have."
We sat in silence, watching the night. Waffle chased a moth across the garden. The children's laughter drifted from inside the house.
Then Damian's phone buzzed. He glanced at the screen. His face went pale.
"What is it?" I asked.
He turned the phone toward me. A text from Dr. Harris.
The research team has completed the full genomic analysis on all four children. There's a pattern they've never seen before. It involves the way their mutations interact. Please come to the hospital tomorrow morning. Bring everyone.
