Her family has launched a GoFundMe to create a shaded garden area where Bridget can safely spend time outdoors without seizures.
A young girl is the only person in the world who has been diagnosed with a specific type of an already rare condition.
Bridget McNally was born in September 2023. Her parents, Christopher and Shelley McNally, noticed she had trouble gaining weight, and Bridget was later diagnosed by a pediatrician with 1q43-q44 deletion syndrome, according to SWNS.
The condition, per the Chromosome Disorder Outreach organization, causes severe developmental delays and seizures due to a deletion at the end of the long arm of chromosome one.
Though there have been over 200 confirmed cases of the deletion syndrome itself, Bridget has a duplication within the chromosome, found through genetic testing, that no other child has been diagnosed with.
"There's no name, just numbers," Christopher, 41, said of his young daughter's condition. "We were told she may never walk as she has muscle weakness, feeding issues and epilepsy."
"She has a very uncomfortable life," he continued of his now 2-year-old daughter, adding that Bridget cannot "sit upright or walk yet, and can't eat like a normal child."
When she was 1, Bridget began experiencing infantile spasm seizures, and later, multifocal seizures. She now sometimes suffers multiple seizures a day.
Because of Bridget's genetic makeup, she is resistant to seizure treatment. She has spent months going in and out of the hospital as doctors try different drugs to help her.
Bridget relies on a "special cot that is controlled for reclining," her father said, as it allows her to sleep upright.
"She cannot lift herself up into the sitting position," Christopher explained.
Bridget also has a monitor that lets her parents check her oxygen levels and heart rate while she is sleeping.
Still, Christopher said his young daughter has been a "fighter" through all her shortcomings.
"We have no idea, and neither does anyone else know, what Bridget's future holds," nanny Christine Wright added.
"Bridget's mom and dad are amazing people who do a great job, but they have, like other families, been through so much," she continued.
Bridget's loved ones currently find support through a 1q4 family deletion group they discovered online. They have been able to meet others who have a similar condition across the world through the group.
Christopher and Shelley have also launched a GoFundMe, with hopes to raise funds to construct a shaded area in their backyard garden where Bridget can sit seizure-free.
The dad of the 2-year-old child said in an update that the family has so far been able to set up a swing set.
