“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.

As it prepares to advance its lead RNA editing candidate, AIR-001, into a phase I/II trial for alpha-1 antitrypsin deficiency, Airna Corp. Inc. closed an oversubscribed $155 million series B financing less than a year after completing its series A round. The company, based in Cambridge, Mass., with research operations in Tübingen, Germany, focuses not only on repairing harmful genetic variants found in rare genetic disorders, but also on introducing beneficial variants that improve health in common conditions.

In the brain, molecular information is transmitted between cells through neural circuits. Synapses establish connections between the pathways that run from one area to another, allowing the most complex organ in the body to fulfill different functions. Cells and neural circuits are the basic biological elements in the study of mental illness. However, the scientific community still does not know how to interpret their role in neuropsychiatric disorders.

Previous studies have shown that protein expression of DOCK7 is increased in skeletal muscle biopsies from patients with Duchenne muscular dystrophy (DMD), leading researchers from the University of Alabama at Birmingham and affiliated organizations to assess the functional impact of DOCK7 on normal muscle and embryonic development of zebrafish.

Researchers from the University of Queensland recently provided details on the discovery and preclinical characterization of a new hematopoietic prostaglandin D2 synthase (HPGDS) inhibitor, CLS-189, being developed for the treatment of Duchenne muscular dystrophy (DMD).
