In the genetics of congenital heart disease, noncoding DNA fills in some blanks
Researchers have been chipping away at the genetic causes of congenital heart disease (CHD) for a couple of decades. About 45 percent of cases of CHD have an identifiable cause, including chromosomal abnormalities, genetic variants affecting protein-coding genes, and environmental factors. What about the rest of the cases of CHD? Noncoding DNA elements have long ... Read More about In the genetics of congenital heart disease, noncoding DNA fills in some blanks
The journey to a treatment for hereditary spastic paraplegia
In 2016, Darius Ebrahimi-Fakhari, MD, PhD, a neurology fellow at Boston Children’s Hospital, met two little girls with spasticity and decreased muscle tone in their legs, which affected their walking. Both girls, Robbie Edwards and Molly Duffy, had been diagnosed with hereditary spastic paraplegia (HSP), a group of more than 80 genetic conditions. Untreated, the ...

Microvillus inclusion disease: From organoids to new treatments
Microvillus inclusion disease (MVID) is a rare type of congenital enteropathy in infants that causes devastating diarrhea and an inability to absorb food. Infants can lose liters of fluid a day, become severely dehydrated, and stop growing. There is no specific treatment. “Until about 10 years ago, 50 percent of kids with MVID would die ...

When diagnosis is just the first step: The Brain Gene Registry
Through advances in genetic sequencing, many children with rare, unidentified neurodevelopmental disorders are finally having their mysteries solved. But are they? “Once families receive results of genetic testing, that’s just the beginning of a new journey,” says Maya Chopra, MBBS, FRACP, an investigator with the Rosamund Stone Zander Translational Neuroscience Center at Boston Children’s Hospital. ...

Calm through the storm: Connor’s ulcerative colitis journey
When you meet Connor today, he’s a confident 13-year-old who is incredibly laid back when he speaks about his complex medical condition. This school year, he plans on playing basketball and running track. “I like hanging out with my friends and traveling — now I can do all these things without being in pain.” However, ...

A global take on rare disease research: Maya Chopra, MBBS, FRACP
Several years ago, while working as a clinical geneticist at the Imagine Institute of Genetic Diseases in Paris, Dr. Maya Chopra saw a child with unexplained intellectual disability, a cleft palate, distinctive facial features, and an inability to speak. Through a genetic analysis, she and her colleagues identified a rare variant in one copy of ... Read More about A global take on rare disease research: Maya Chopra, MBBS, FRACP
DADA2: Working together to unpack a rare mystery illness
When Vanessa was a few months old, a mysterious red, bumpy rash appeared on her arms and legs. It would go away when she was sick with a virus, then come back. Although the rash disappeared for good just before she turned 2, Vanessa became anemic and increasingly fatigued. “She was fading away, losing weight, ...

Virtual visits give Weston time to grow and thrive
For many kids and parents, staying home during the COVID-19 pandemic was a challenge. But for Weston Mahady and his family, social distancing was just what the doctor ordered. The slowed-down pace, time spent together — and access to virtual appointments with Boston Children’s specialists — allowed Weston to make developmental strides that once hadn’t ...

Playing the long game: An exciting discovery in telomere disease
Each time our cells divide, the protective caps that keep our chromosomes from fraying, called telomeres, lose a bit of their DNA. Telomeres shorten steadily as we age, but in certain medical conditions like dyskeratosis congenita, the process is accelerated. “Your telomeres determine your lifeline; how long they are determines how old your body is,” ...

Conquering a rare metabolic condition: A family, a pediatrician, and two labs join forces
As a newborn, Sam Hoffman never cried or made a sound. His mother, Carolyn, often had to wake him up to feed him. He missed many of his infant milestones. At one visit, his pediatrician tapped his leg and couldn’t get a reflex. A urine test found extremely high levels of 4-hydrobutyric acid or GHB ...
