When George was diagnosed with Mosaic Variegated Aneuploidy (MVA) at just 2 years old, his family was told there were no treatments, no specialists, and no reliable information to guide them. The condition was so rare that most doctors had never heard of it.

His parents were left to navigate the frightening complexities of MVA on their own - from growth delays and developmental concerns to increased cancer risk. They were told it was “untreatable” and that they should “wait and see.”

But waiting wasn’t good enough, so they founded the MVA Society to change that story, not just for George - but for everyone living with this ultra-rare condition.

George’s diagnosis highlighted a frightening truth: MVA was virtually invisible to the medical and research world. Fewer than 50 people globally were known to be affected. Families had no access to advocacy, and clinicians lacked clear information and treatment pathways. Even experienced healthcare professionals had no guidance for how to support patients with MVA.

This silence was not just dangerous, it was unacceptable.

And MVA isn’t just a childhood condition. People live with it their entire lives. Adults with MVA face ongoing health challenges including developmental delays, cancer risk, and complex organ system issues. But without a body of knowledge or coordinated care, most receive fragmented or inconsistent support, if any.

The MVA Society was created to fill that gap, for children like George and for adults around the world still seeking answers.

Refusing to accept “nothing can be done,” George’s parents began building a support system from the ground up. They partnered with expert clinicians, connected with researchers, and began funding targeted studies that could lead to real treatments.

George became the youngest patient in the world to receive Nano Knife Technology to treat a liver tumour, which required careful coordination across international specialists.

And today, he is thriving because of bold, expert-led decisions made possible through the Society’s work.
His story proves what’s possible when families aren’t left to face rare disease alone.

The MVA Society is committed to supporting every person affected by MVA, at every age. We work with healthcare professionals across paediatrics, oncology, genetics, and more. MVA doesn’t disappear in adulthood, it’s challenges evolve and so must our care and work.

We provide:

• Lifespan-focused patient advocacy - from infancy to adulthood
• Guidance for healthcare professionals treating MVA at any stage
• Access to cutting-edge research and treatment pathways
• A global community where no one is left behind

George's story may have started this mission - but it’s the stories of every person living with MVA that drive us forward.
