Cork Mother Shares Heartbreaking Journey of Daughter’s Rare Genetic Condition

In a story that underscores the resilience of families facing rare medical conditions, a Cork mother has opened up about her daughter’s battle with KCNQ2 Encephalopathy—a devastating genetic disorder that left the infant experiencing hundreds of seizures daily. Hannah McGrenera, a mother of two from Bishopstown, recounted the harrowing early days of her daughter Mila’s life, marked by uncertainty, fear and an eventual diagnosis that changed everything.

The First Signs: A Mother’s Instinct

Mila was born in 2020 at Cork University Hospital (CUH), but within hours, Hannah knew something was wrong. “The night she came home, I knew something wasn’t right due to the fact that she wasn’t feeding,” Hannah told RSVP Live. The situation escalated quickly. Mila was rushed back to the hospital’s A&E department, where she was eventually admitted to the Intensive Care Unit (ICU). What followed was a month-long stay in the ICU, followed by an entire year in the pediatric unit at CUH.

During this time, Mila’s condition deteriorated rapidly. She experienced hundreds of seizures a day, along with episodes of breath-holding that left her turning purple and black. “We just didn’t know what was wrong with her,” Hannah recalled. The lack of answers left the family in a state of despair, grappling with the unknown while watching their newborn struggle for survival.

The Diagnosis: KCNQ2 Encephalopathy

After months of exhaustive testing, doctors finally identified the cause of Mila’s seizures: KCNQ2 Encephalopathy, a rare genetic condition that disrupts the brain’s electrical activity. The disorder is caused by mutations in the KCNQ2 gene, which plays a critical role in regulating the flow of potassium ions in neurons. When this gene malfunctions, it leads to severe epilepsy, developmental delays, and, in many cases, life-threatening complications.

According to the U.S. National Library of Medicine, KCNQ2 Encephalopathy affects fewer than 1 in 100,000 children worldwide. The condition typically manifests in the first days or weeks of life, with infants experiencing frequent, drug-resistant seizures. Developmental delays, intellectual disability, and movement disorders are common long-term effects, though the severity varies from child to child.

What Is KCNQ2 Encephalopathy?

• Genetic Cause: Mutations in the KCNQ2 gene, which is responsible for producing a protein that helps control electrical signaling in the brain.
• Symptoms: Seizures (often within the first week of life), developmental delays, muscle stiffness or weakness, and breathing difficulties.
• Diagnosis: Genetic testing is required to confirm the mutation. EEGs and MRI scans are often used to assess brain activity and structure.
• Treatment: No cure exists, but anti-seizure medications, physical therapy, and specialized care can help manage symptoms.

A Year in the Hospital: Exhaustion and Fear

Mila’s year-long hospitalization took an immense toll on Hannah and her family. “I remember thinking, how was I going to manage things by myself when there was a whole nursing team in the hospital,” she said. The emotional and physical exhaustion was overwhelming. “I was scared, defeated, and totally hopeless. It was the darkest time of my life.”

When doctors exhausted all treatment options, Mila was discharged—leaving Hannah to navigate the challenges of caring for a medically fragile child at home. The transition was daunting. “I was completely exhausted, mentally and physically,” she admitted. But help arrived in an unexpected form: the Jack and Jill Children’s Foundation, an Irish charity that provides in-home nursing care for children with severe medical needs.

Jack and Jill: A Lifeline for Families

Eilín Ní Mhurchú, a liaison nurse manager with Jack and Jill, visited Hannah and offered immediate support. “It was as simple as that,” Hannah said. “I didn’t have to fill out twenty pages of information telling her how sick Mila is; it was just so easy.”

The foundation provided nurses who visited the family’s home, offering respite care for Hannah and specialized medical support for Mila. “For two or three hours, they will peg-feed her and help keep her comfortable and happy,” Hannah explained. The nursing hours are tailored to each family’s needs, ensuring that parents like Hannah can take breaks while knowing their child is in capable hands.

Jack and Jill supports over 400 children across Ireland, offering up to 80 hours of nursing care per month to families in demand. The charity relies on donations and fundraising to continue its work, making stories like Hannah and Mila’s a testament to the impact of community support.

Raising Awareness Through Art

Determined to give back, Hannah has channeled her creativity into raising funds for Jack and Jill. As an artist, she has collaborated with the charity to create unique pieces that highlight the struggles and triumphs of families like hers. “It’s my way of saying thank you,” she said. “They were there for us when we needed them the most, and now I seek to help other families who are going through the same thing.”

Her efforts are part of a broader movement to raise awareness about rare genetic conditions like KCNQ2 Encephalopathy. While the disorder is rare, it is one of many epilepsy syndromes that affect children in Ireland, where an estimated 40,000 people live with epilepsy. Advocacy groups, including Epilepsy Ireland, emphasize the need for better research, early diagnosis, and access to specialized care.

The Road Ahead: Hope and Challenges

For Hannah and Mila, the journey is far from over. While Mila’s seizures have turn into more manageable with medication, her developmental delays present ongoing challenges. “Every tiny milestone is a victory,” Hannah said. “Whether it’s holding her head up for a few seconds or making eye contact, we celebrate it all.”

The family’s story has resonated with many, shining a light on the often-invisible struggles of parents caring for children with rare diseases. It also highlights the critical role of organizations like Jack and Jill, which provide a lifeline to families in crisis.

Key Takeaways

• KCNQ2 Encephalopathy is a rare genetic disorder causing severe epilepsy and developmental delays, typically diagnosed in infancy.
• Symptoms include hundreds of seizures a day, breath-holding episodes, and muscle stiffness.
• Diagnosis requires genetic testing, and there is currently no cure—only symptom management.
• Support systems like the Jack and Jill Children’s Foundation provide in-home nursing care to families in Ireland.
• Awareness and fundraising are crucial for advancing research and supporting affected families.

FAQ

What causes KCNQ2 Encephalopathy?

KCNQ2 Encephalopathy is caused by mutations in the KCNQ2 gene, which disrupts the brain’s electrical signaling. This leads to seizures and developmental delays.

How common is KCNQ2 Encephalopathy?

The condition is extremely rare, affecting fewer than 1 in 100,000 children worldwide. Still, it is one of several genetic epilepsy syndromes that collectively impact a significant number of families.

What treatments are available?

There is no cure for KCNQ2 Encephalopathy. Treatment focuses on managing seizures with medication, physical therapy, and specialized care to support development.

How can I support families affected by rare conditions?

Donating to organizations like Jack and Jill or Epilepsy Ireland can provide direct support to families. Advocating for better research funding and healthcare policies is also crucial.

Looking Forward

Stories like Hannah and Mila’s remind us of the resilience of the human spirit in the face of adversity. While rare conditions like KCNQ2 Encephalopathy present immense challenges, they also highlight the power of community, advocacy, and hope. As research advances and awareness grows, there is reason to believe that families like the McGreneras will one day have access to better treatments—and perhaps even a cure.

For now, Hannah’s message is one of gratitude and perseverance. “We take it one day at a time,” she said. “And we’re not alone.”
