Raphaela Muri and Roman Trepp join the JIMD Podcast to explore what happens to the adult brain in phenylketonuria. We discuss the effects of phenylalanine exposure on brain structure, what MRI studies reveal about potentially reversible changes, how these findings relate to cognition, and whether the latest evidence really suggests altered brain ageing in early-treated PKU. Papers discussed and…
Research Round-Up: Sterols and Bile Acids by Journal of Inherited Metabolic Disease
Júlio César Rocha, Anne Daly and Anita MacDonald discuss how nutritional management can move beyond metabolic control towards better lifelong health. From protein substitutes and point-of-care monitoring to new therapies and AI, what might the future look like? From Control to Optimisation: Evolving Strategies in the Nutritional Management of Inborn Errors of Protein Metabolism Júlio César Rocha,…
Sarah Firman explores how dietary management can rapidly reduce phytanic acid levels in adult Refsum disease. This case series shows why adequate energy and carbohydrate intake, and avoiding weight loss and catabolism, matter alongside phytanic acid restriction. Adult Refsum Disease: Case Series of Reducing Circulating Phytanic Acid Levels With Dietary Interventions Sarah J. Firman, et al…
Are inherited metabolic disorders more common, and less predictable, than we previously thought? Large-scale genomic studies are identifying adults with disease-associated variants who have escaped diagnosis, sometimes despite lifelong symptoms. At the same time, expanding genomic newborn screening risks identifying children who may remain well for decades or never develop clinically significant…
Phenylketonuria (PKU) was one of the first inherited metabolic disorders to be recognised, but there is still plenty to discover. Silvia Radenkovic and Rodrigo Starosta are joined by Dr Cary Harding and Dr Wendy Smith to discuss evolving treatments, updated management guidelines and where PKU research is heading next. The views and opinions expressed in this podcast are those of the speakers and…
A study of rapamycin in Niemann-Pick C raises an important question: what if the success of a treatment depends on a patient's wider genetic background? Dr Andrés Klein discusses pharmacogenomics, modifier genes and why precision medicine may need to go far beyond making the diagnosis. A Rapamycin Pharmacogenomic Approach for the Childhood Dementia Niemann-Pick C Benjamín Szenfeld, et al…
In this JIMD Shortcast, first author Arty Selvanathan discusses their study exploring how clinical outcomes relate to biochemical findings in cobalamin C (cblC) disease. What can biochemical markers really tell us about disease severity, and where do their limitations lie? Clinical Outcomes and Correlation With Biochemical Control in Hydroxocobalamin-Treated Patients With Early-Onset Cobalamin C…
How much of metabolic control in methylmalonic acidemia is determined by diet, and how much by the microbiome? In this episode, Engin Köse discusses a prospective longitudinal study exploring protein composition, gut microbial changes, and the impact of metronidazole on biochemical control in MMA. Dietary Protein Modulation, Gut Microbiota, and Metabolic Control in Methylmalonic Acidemia: A…
In this Shortcast Dr Mark Wijnen presents two cases where Teriparatide was used to treat bone complications in MPD IVB but explains how temporally associated cardiac disease compels his groups to advise caution in its use. Teriparatide in Two Patients With Mucopolysaccharidosis Type IVB Mark Wijnen, Evert F. S. van Velsen, J. Gert-Jan Milhous, Esmee Oussoren, Bram C. J. van der Eerden, Margreet A.…
