One of Just Nine in the World, Toddler Lives with an Ultra-Rare Chromosome Deletion That Leaves Doctors Searching for Answers

A two-year-old girl is one of only nine known people in the world living with an ultra-rare genetic condition that is so uncommon it does not even have an official name.
Ellouise Thompson, from York, England, has a chromosome disorder known as 3p26.3-25.3 deletion, an exceptionally rare genetic deletion estimated to affect just one in 820 million people. Because so few cases have ever been identified, doctors still know very little about the condition or what the future may hold for children diagnosed with it.
The disorder has been ᴀssociated with developmental delays as well as possible heart, kidney, and bowel problems. Ellouise is currently unable to speak or hear and continues to undergo ᴀssessments and therapies to support her communication and cognitive development.

Her parents first realized something was different when Ellouise was still a baby.
“She never cried, even when she hurt herself, and she didn’t make the usual babbling sounds,” her mother, Emma Thompson, recalled.
Concerned, Emma and her husband, Jon, sought medical advice several times. Although they knew something wasn’t right, finding answers proved difficult because the condition was far beyond what most pediatric specialists encounter.
After months of testing, Ellouise finally received her diagnosis.
“When we found out, we were completely heartbroken,” Emma said. “We were just numb with fear.”
While the diagnosis brought emotional pain, it also provided an important opportunity for Ellouise to receive specialized care and support much earlier than many children with rare genetic disorders.

“In some families we’ve spoken to, children weren’t diagnosed until they reached school age,” Emma explained. “At least now Ellouise can begin getting the help she needs.”
Today, Ellouise is one of just three known cases in the United Kingdom. Because information about the condition is so limited, her family has relied heavily on Unique, a charity that supports people affected by rare chromosome and gene disorders.
Emma says connecting with other families facing similar challenges has been invaluable.
“We still don’t know what the future holds for Ellouise, but with Unique’s help, we’ll continue fighting to get the support she needs so she can thrive in her own unique way.”
Her father, Jon, said the charity has transformed the family’s journey.
“Without their support, we’d have been left in a black hole of worry and uncertainty. The experiences shared by other families have helped guide our conversations with doctors, shaped our understanding of what’s possible, and shown us how best to support Ellouise.”
To help other families facing rare chromosome disorders, Emma has pledged to complete a 100-mile charity bike ride to raise funds for Unique, hoping that greater awareness and research will one day provide more answers for children like Ellouise.
Although many questions remain about her condition, Ellouise continues to inspire those around her with her determination, while her family remains committed to ensuring she receives every opportunity to reach her full potential.
