Mason Axel Rockenfield, a bright and loving young boy known for his kind heart and 4.0 GPA, is currently fighting for his life.
In early June, while supporting his sister at a basketball tournament in St. George, Mason suddenly experienced a severe medical emergency.
He lost movement on the right side of his body and quickly became unresponsive.
He was rushed to the hospital, sedated, intubated, and flown by life flight to Primary Children’s Hospital in Salt Lake City.
Initially, doctors observed stroke-like symptoms, but further testing revealed that Mason did not suffer a stroke.
Later, he was diagnosed with Multiple Sclerosis (MS), an autoimmune disease affecting the brain and spinal cord.
Despite treatment plans, Mason’s condition worsened, and he began experiencing tremors, loss of balance, and the inability to play the piano, a beloved activity.
MRI scans revealed aggressive lesions in his brain, raising concerns that he might have the rare Marburg variant of MS. Mason was immediately placed on intensive treatments, including plasma exchange.
In October 2025, after months of uncertainty, Mason’s family finally received a definitive diagnosis: Griscelli Syndrome Type 2, an extraordinarily rare immune disorder affecting fewer than 150 people worldwide.
This condition triggered a life-threatening immune reaction known as Hemophagocytic Lymphohistiocytosis (HLH), which attacked Mason’s brain and lungs.
The new diagnosis explained why earlier treatments had only partially controlled his symptoms.
Currently, Mason remains on veno-venous ECMO, the highest form of life support, alongside mechanical ventilation and heavy sedation.
Doctors have begun chemotherapy and high-dose steroids to suppress his overactive immune system.
The ultimate hope for Mason’s recovery is a bone marrow transplant, which will only be possible if he stabilizes and becomes strong enough to endure the procedure.
Depending on his lung recovery, a lung transplant may also be considered.
The Rockenfield family continues to care for Mason around the clock, supported by a dedicated medical team.
They have also faced immense financial strain due to mounting medical bills and lost income.
Despite the challenges, the family is buoyed by the love and support from friends, classmates, and their community.
Mason’s family asks for continued prayers, encouragement, and support as he fights this rare and critical condition.
Every act of kindness and generosity has lifted their spirits during this overwhelming journey.
