Reshaping the Treatment Landscape of a Galactose Metabolism Disorder

Published On 2025 Feb 15

Journal article

The Leloir pathway was elucidated decades ago, unraveling how galactose is metabolized in the body. Different inborn errors of metabolism in this pathway are known, the most frequent and well-studied being Classic Galactosemia (CG) (OMIM 230400) due to pathogenic variants in the GALT gene. Substrate reduction using dietary restriction of galactose is currently the only available treatment option. Although this burdensome diet resolves the life-threatening clinical picture in neonates, patients...


Enriched phenotypes in rare variant carriers suggest pathogenic mechanisms in rare disease patients

Published On 2025 Jan 17

Journal article

CONCLUSIONS: Analyses of large-scale population cohorts such as the UKB can be a critical tool to further our understanding of rare diseases in general. Continued research in this area could lead to more precise diagnostics and personalized treatment strategies for patients with rare and undiagnosed conditions.
