Using a customized gene editing therapy, researchers at the Children’s Hospital of Philadelphia have reported success in treating an infant with a severe metabolic disorder. Kiran Musunuru, Barry J. Gertz Professor for Translational Research in the University of Pennsylvania’s Perelman School of Medicine, presented the case at the American Society of Gene and Cell Therapy’s 2025 annual meeting. The case study was simultaneously published in The New England Journal of Medicine.

Metabolic disorders such as argininosuccinic and glutaric aciduria, methylmalonic acidemia, homocystinuria or primary hyperoxaluria require specific diets to prevent the accumulation of substances that the body can’t process. Current treatments mainly focus on managing symptoms and metabolite levels, and do not always prevent the progressive deterioration caused by mutations associated with the condition. However, emerging gene therapies hold promise for transforming these diseases by targeting their underlying causes, as presented in the oral abstract session, “Gene and cell therapy for metabolic diseases” of the ongoing 28th Annual Meeting of the American Society of Gene & Cell Therapy (ASGCT) meeting in New Orleans.

Ensoma Inc. has obtained IND clearance from the FDA for its lead program EN-374 in X-linked chronic granulomatous disease (X-CGD).

Scientists at the Center for Genomic Regulation (CRG) have developed an AI-based tool to design thousands of sequences that regulate DNA. They have also synthesized these molecules, called enhancers, to control gene activation in mouse hematopoietic stem cells, which they have tested in vitro.

“I’m a pediatrician in metabolic diseases, and every day in my clinical work I’m confronted with our lack in effective therapies for our patients.” That was the sobering introduction by Sabine Fuchs in her talk at the 2025 Congress of the European Association for the Study of the Liver in Amsterdam this week. The nature of metabolic diseases makes it difficult to develop treatments for them. “There are over 1,500 diseases known by now, and it is just very difficult to develop therapies for each and every individual rare disease.”

Innorna Co. Ltd.’s investigational mRNA therapy, IN-013, has been awarded orphan drug and rare pediatric disease designations by the FDA for the treatment of Wilson disease.

A large-scale study has revealed the impact of germline variants on proteins in 10 cancer types. Scientists from the National Cancer Institute’s Clinical Proteomic Tumor Analysis Consortium (CPTAC) conducted a precision proteogenomic analysis in a pan-cancer study with data from 1,064 patients, identifying tumor heterogeneity and tumorigenesis associated with heritable genetic alterations.

The results provide a broad view of cancer risk that could be useful for patient stratification and the design of prevention strategies.

Researchers from Pretzel Therapeutics Inc. and the University of Gothenburg have published new insights on how mutations in the POLG gene affect its functionality and are tied to PolG diseases. They have also presented a compound for its potential treatment, PZL-A. They published their results in Nature on April 9, 2025.
