Similarities among three pediatric brain tumors that arise in different structures of the CNS – pineoblastoma, retinoblastoma and Group 3 medulloblastoma – have been linked to their shared origin during pineal gland development. Scientists at St. Jude Children’s Research Hospital have identified the molecular signatures that drive these tumors from pinealocyte progenitor cells that conserve a common differentiation program, providing a shared therapeutic target for these three cancer types.

Hypoxic-ischemic brain injury (HIBI) is a condition affecting neonates and is a leading global cause of perinatal neurological morbidity, with limited therapeutic options. Regarding its pathogenesis, the ion channel-kinase transient receptor potential melastatin 7 (TRPM7) is a known contributor to HIBI pathology and was the focus of a recently reported study.

Leigh syndrome is a fatal pediatric neurodegenerative disorder caused by mitochondrial dysfunction, most often due to defects in the mitochondrial respiratory chain. The Ndufs4 knockout (Ndufs4 KO) mouse is an established model of the disease, as loss of the NDUFS4 subunit leads to complex I (CI) deficiency and reproduces the neurological decline and pathology seen in affected children. Researchers from The Children’s Hospital of Philadelphia Research Institute and collaborators described how NV-354, a water-soluble prodrug of succinate, may mitigate this mitochondrial dysfunction.

Genedx Holding Corp. launched Genomedx Prenatal, its whole genome sequencing test, to provide more definitive diagnoses of the causes of fetal abnormalities identified by ultrasound. By combining the company’s decade of experience in prenatal exome testing and its massive Genedx Infinity rare disease dataset, the test can determine not just whether a pregnancy has a risk of a genetic disorder but whether the fetus actually has a genetic disorder.

Gene editing technologies are moving forward in preclinical development with innovative strategies designed to treat diseases at their root and even reverse them.

Gene editing technologies are moving forward in preclinical development with innovative strategies designed to treat diseases at their root and even reverse them. However, many approaches still struggle to reach target cells or tissues – either they fail to arrive, or their efficacy is low. In vivo therapies face numerous challenges, but despite these hurdles, 2025 has marked a year of remarkable progress.

Crescom Co. Ltd., an AI musculoskeletal imaging company, gained U.S. FDA 510(k) clearance Dec. 24 for MediAI-BA, its AI-powered pediatric and adolescent bone age analysis software. Classified as a class II medical device, MediAI-BA evaluates bone age and suggests predicted adult height based on growth plate status assessed by hand and wrist X-ray imaging. Prior clinical trial results demonstrated MediAI-BA had specialist-level accuracy, recording a mean absolute deviation (MAD) of 0.39 years.

After being unanimously passed by the U.S. House Dec. 1, the bipartisan Mikaela Naylon Give Kids a Chance Act seemed to be headed for sure passage in the Senate before it adjourned late last week.
