RNA‐Based Therapies for Inherited Metabolic Disorders

open access: yesJournal of Inherited Metabolic Disease, Volume 49, Issue 2, March 2026.
ABSTRACT Inherited metabolic disorders (IMDs) are a diverse and complex group of genetic conditions resulting from deficiencies in enzymes, transporters, or cofactors. These deficiencies lead to metabolic dysfunction and severe clinical consequences. Despite significant progress in understanding their molecular basis, treatment options remain limited ...

Expert‐Designed Fact Sheets and AI‐Based Analysis of Patient Symptoms to Combat Diagnostic Delays in Inherited Metabolic Diseases

open access: yesJournal of Inherited Metabolic Disease, Volume 49, Issue 2, March 2026.
ABSTRACT The importance of early diagnosis of inherited metabolic diseases (IMDs) is well known, as it allows early intervention to prevent or reduce complications and improve prognosis, since many of these disorders are treatable. However, diagnosis can still be delayed, and many patients remain undiagnosed. Reducing diagnosis delays is a primary goal
