With First Birthday, Anna Defies Odds of Trisomy 13
Despite her condition, Anna enjoys a good quality of life
Megan and Neil DeRuiter never thought they would be celebrating their daughter Anna’s first birthday.
Born with trisomy 13 – a rare and life-limiting genetic disorder in which a baby has an extra 13th chromosome – Anna wasn’t expected to live past her first month.
But Anna’s case proved to be comparably mild. And now one year later, she is defying the odds and opening presents.
Daniel T. Swarr, MD, a neonatologist and geneticist who studies trisomy 13, describes the bleak reality for most families and the ray of light for others like the DeRuiters.
“The majority do pass away in their first 1-2 weeks of life, but there seems to be a small subset of children with trisomy 13 – on the order of 10-20 percent – who live for quite a long period of time,” said Swarr. “Those that survive the first six months to a year often live for many years afterward.”
Anna is different from most babies born with trisomy 13, in that she didn’t have the same life-threatening birth defects or breathing problems that lead to early death, according to Leandra Tolusso, a prenatal genetic counselor.
“While we don’t completely understand why some kids with this condition do “better” than others, we do know that certain factors – such as not having a serious congenital heart defect – are associated with longer survival,” said Tolusso.
Even more good news is that Anna is getting bigger, eating well and meeting more developmental milestones.
Significant improvement in her obstructive sleep apnea means she no longer needs to wear oxygen during the day, only at night. Ongoing treatment will continue at both Cincinnati Children’s and near the family's home in West Virginia for a wide range of other conditions, including seizures, speech therapy, occupational and physical therapy, congenital heart disease, eye conditions and dietary needs.
Some might see a list of conditions but Megan sees something else. She sees a happy child. She sees her daughter smiling and playing every day. She sees a good quality of life.
Swarr smiles too when he hears of Anna’s continued success, and that of other patients like her. He believes their milestones and achievements should not only be celebrated, but also studied by geneticists around the country who can learn more about the developmental outcomes of children like Anna.
“I think we can learn from all our patients, as physicians. And particularly from someone like Anna,” said Swarr. “It’s valuable for all of us to learn from her and the experiences of her family.”
