Mutations during prenatal development may contribute to schizophrenia
Schizophrenia is known to have a genetic component, and variants in 10 genes have been identified as markedly increasing schizophrenia risk. But together, these genes account for under 5 percent of cases. Now, a pilot study in the journal Science suggests another important contributor to schizophrenia: distinctive patterns of non-inherited (somatic) mutations. These mutations appear ...

Breaking new ground in cerebral cavernous malformation research
Children with cavernous malformations face unique treatment challenges due to factors such as the malformation’s location, size, risk of bleeding, and the complexities of pediatric tissue development. To address these issues effectively, advanced diagnostics and precise interventions are essential. This is why Ed Smith, MD, and the team at the Cerebrovascular Surgery and Interventions Center ...

All in it for Hudson: A family’s shared path with cavernous malformations
Three-year-old Hudson loves trucks and PAW Patrol. He’s a delightful blend of sweet, fun, and feisty, and — after a seizure on New Year’s Day led to an extended stay at Boston Children’s Hospital — he’s an inspiration to his parents, Gabrielle and Matthew. To Matthew specifically, Hudson provides a new look at his own ... Read More about All in it for Hudson: A family’s shared path with cavernous malformations
A new anti-cancer strategy: Overriding tumor edits
Cancers are clever and often find ways to dodge people’s immune systems, making them hard to eradicate. Immunotherapies such as CAR-T cells and checkpoint inhibitors can sharpen the immune system’s attack and cure the cancer. But they don’t work for most solid tumors. We now know that tumors can edit their genes to evade immune ... Read More about A new anti-cancer strategy: Overriding tumor edits
Making genome sequencing a first-line test in rare disease
Children with rare diseases often undergo years of medical visits and genetic testing before they get a diagnosis. Over the past few years, clinics have started to embrace exome sequencing as a first genetic test, skipping time-consuming testing of individual genes and gene panels and getting to a diagnosis faster. But exome sequencing doesn’t always ... Read More about Making genome sequencing a first-line test in rare disease
Two rising stars in kidney genetics: Nina Mann and Amar Majmundar
A healthy, functional kidney must maintain a delicate balance of water, nutrients, and electrolytes so it can properly filter the blood and produce urine. That often makes caring for patients with kidney disease an exercise in chemistry and mathematics — an aspect of nephrology that attracted two young physician-scientists. Coming from different paths, Nina Mann, ... Read More about Two rising stars in kidney genetics: Nina Mann and Amar Majmundar
Whether she’s embracing school, sports, or music, Lindsey shows how Williams syndrome can be managed
One of the first things Lindsey Franco will tell you is, “I like being me. I like being happy.” The 19-year-old has a lot to be happy about. She attends a post-high school transition program that helps young adults expand their social and life skills. There, she does all the things she enjoys, including playing ...

‘Empowered to be there for Teagan’: New parents learn about hearing loss
Teagan O’Brien is a bright, spunky 4-year-old who loves reading, dancing, and playing outdoors. Her parents, Kim and Donnie, are firefighters who throw themselves into any new situation. Since they adopted Teagan three-and-a-half years ago, they’ve thrown themselves into supporting her with help from her team at Boston Children’s Hospital. Teagan was already a patient ...

A journey through the intestine during colitis, cell by cell
Inflammatory bowel disease (IBD), causing devastating abdominal pain, persistent diarrhea, and rectal bleeding, is hard to control with current treatments. Children often experience malnutrition and impaired growth. To get a better handle on IBD, researchers at Boston Children’s Hospital and Brigham and Women’s Hospital decided to eavesdrop on happenings in the colon. In the first ...

Genetic variants are found in two types of strabismus, sparking hope for future treatment
Determining how genetics contribute to common forms of strabismus has been a challenge for researchers. Small discoveries are considered meaningful progress. Boston Children’s researchers believe they’ve helped move the needle. They discovered that two types of strabismus — esotropia and exotropia — may have shared genetic risk factors. Duplications on the second, fourth, and tenth chromosomes that ... Read More about Genetic variants are found in two types of strabismus, sparking hope for future treatment
