Leigh Syndrome https://www.nature.com/articles/s42255-026-01566-0 Mitochondria are often described as the “powerhouses” of cells because they produce energy needed for cells to function. A key part of this process is the electron transport chain, which contains five protein complexes. Complex 1 is the largest and is particularly important for energy production, therefore problems affecting Complex 1 can […]

Fucosidosis https://www.cureus.com/articles/497493#! Fucosidosis is an extremely rare inherited disorder caused by the lack of an enzyme called α‑L‑fucosidase, which leads to the buildup of certain sugars in the brain and other organs. This case report follows an 18‑year‑old girl over 15 years, showing how her brain scans changed as the disease progressed. Early MRI scans […]

Alexander disease (AxD) https://www.sciencedirect.com/science/article/pii/S1096719226004725 Alexander disease (AxD) is a rare leukodystrophy, where Type 1 AxD usually begins in infancy or early childhood and is caused by pathogenic variants, in the GFAP gene, which provides instructions for making glial fibrillary acidic protein (GFAP) in astrocytes. Pathogenic variants are changes in the DNA that have been confirmed […]

Adrenoleukodystrophy (ALD) https://pmc.ncbi.nlm.nih.gov/articles/PMC13234235 X-linked adrenoleukodystrophy (X-ALD) is a disorder caused by changes in the ABCD1 gene. These changes disrupt adrenoleukodystrophy protein (ALDP), a protein involved in transporting very long-chain fatty acids (VLCFAs) into peroxisomes, where they are normally broken down. As a result, VLCFAs build-up throughout the body including in lipids. However, serious effects of […]

The Phase 3 GM1/GM2 study enrolled a minimum of 75 patients across 25 clinical sites in 13 countries. The study is evaluating oral administration of nizubaglustat compared to […]

Adrenoleukodystrophy (ALD) https://www.minoryx.com/media/leriglitazone_receives_a_positive_chmp_opinion_for_the_treatment_of_cerebral_adrenoleukodystrophy Minoryx Therapeutics and Neuraxpharm Group have announced that European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) has recommended granting marketing authorisation approval under exceptional circumstances for NEZGLYAL® (leriglitazone) as a treatment for male cALD patients, aged 2-12 years with Gadolinium (Gd) negative brain lesions. Gadolinium is a clear […]

Vanishing White Matter Disease (VWMD) Vanishing white matter (VWM) is a rare inherited neurological disease that mainly affects children. It damages the brain’s white matter, leading to progressive problems with movement, coordination, speech, and thinking. Even minor illnesses, fever, or head injuries can trigger sudden and irreversible worsening of symptoms. Studies in mice suggested that […]

Peroxisome Biogenesis Disorder (PBD) https://www.nature.com/articles/s41551-026-01651-5 Zellweger spectrum disorder (ZSD) is a rare inherited condition caused by changes in genes that help cells build peroxisomes. Peroxisomes play an essential role in breaking down certain fats and removing harmful substances from the body. When they do not work properly, toxic substances build up, causing damage to multiple […]

Leigh Syndrome https://www.sciencedirect.com/science/article/pii/S2213231726001643 This study explores how problems in mitochondria—the cell’s main energy producers—affect another organelle called the peroxisome, which also helps break down fats. The researchers used cells lacking NDUFS4, a key part of mitochondrial complex I. Without this protein, mitochondria cannot properly burn fatty acids, causing the cells to accumulate excess fat. Normally, […]

GM2 gangliosidosis https://www.sciencedirect.com/science/article/pii/S1096719226004476 GM2 gangliosidoses and Niemann–Pick type C (NPC) disease are rare inherited conditions that damage the brain and nervous system over time. People living with these disorders can experience difficulties with movement, balance, speech, swallowing, learning, and seizures. While treatments are available to help slow NPC disease, there are currently no disease-modifying therapies […]
