Baby Boy Is One of Just 16 Children Known to Have a Rare Condition That Doesn’t Even Have a Name

For Amanda and Nick Thomas, welcoming their baby boy Jack should have marked the beginning of a lifetime of precious family memories. Instead, they found themselves facing a devastating diagnosis involving a genetic condition so rare that doctors could offer few answers about their son’s future.

At just 11 months old, Jack was identified as one of only 16 children worldwide known to have a mutation affecting the PPFIBP1 gene, according to BBC reporting in June 2025.

The condition has left him blind, experiencing frequent seizures and facing profound developmental challenges.

A Diagnosis With Almost No Answers

Jack’s parents, from St Athan in the Vale of Glamorgan, Wales, learned that their son’s condition was exceptionally rare and life-limiting.

Unlike more commonly diagnosed childhood disorders, the genetic condition associated with PPFIBP1 had no widely established disease name at the time of the family’s interview.

Doctors explained that Jack was unlikely to develop the ability to walk or talk and that his condition could significantly shorten his life.

However, the scarcity of documented cases made it difficult for specialists to predict exactly how his health would progress.

A Mother Facing an Uncertain Future

For Amanda, one of the hardest parts of the diagnosis was learning that doctors could not tell her how much time she might have with her son.

His condition is considered life-limiting, but there is no clear timeline for how it will develop.

Every seizure, medical appointment and developmental challenge adds another layer of uncertainty to everyday family life.

Despite these difficulties, Amanda and Nick remain focused on caring for Jack and making the most of their time together.

Searching the World for Other Children Like Jack

With so few documented cases, Jack’s parents began searching for families whose children have the same genetic condition.

Their goal is to better understand what other children have experienced, share information and establish connections with parents facing similar challenges.

Amanda has already spoken with another mother whose daughter had the condition and died at the age of two.

Although hearing about another family’s loss was heartbreaking, connecting with people who understand the diagnosis has become an important part of their search for answers.

Making Every Moment Count

Jack’s story highlights the extraordinary uncertainty faced by families affected by ultra-rare genetic disorders.

When only a small number of patients have been identified, parents may struggle to find established treatment pathways, reliable prognostic information or other families who understand their experiences.

For Amanda and Nick, sharing their son’s story is about more than raising awareness. It is also an attempt to find a community, exchange knowledge and help other families feel less isolated.

While Jack’s future remains uncertain, his parents continue to surround him with love and care, celebrating the precious moments they share with their little boy.
