Severe neonatal hypotonia due to SLC30A5 variant affecting function of ZnT5 zinc transporter

Vadim Dolgin, PAULINE L. CHABOSSEAU, Jacob Bistritzer, Iris Noyman et autres

Abstract The tightly‐regulated spatial and temporal distribution of zinc ion concentrations within cellular compartments is controlled by two groups of Zn2+ transporters: the 14‐member ZIP/SLC39 family, facilitating Zn2+ influx into the cytoplasm from the extracellular space or intracellular organelles; and the 10‐member …

Biochemical and neurophysiological effects of deficiency of the mitochondrial import protein TIMM50

Eyal Paz, Sahil Jain, Irit Gottfried, Orna Staretz‐Chacham et autres

TIMM50, an essential TIM23 complex subunit, is suggested to facilitate the import of ~60% of the mitochondrial proteome. In this study, we characterized a TIMM50 disease-causing mutation in human fibroblasts and noted significant decreases in TIM23 core protein levels (TIMM50, TIMM17A/B, and …

Newborn screening algorithm distinguishing potential symptomatic isovaleric acidemia from asymptomatic newborns

Rachel Rock, Oded Rock, Suha Daas, Vered Biton‐Regev et autres

Newborn screening (NBS) for isovaleric acidemia (IVA) reduces mortality and morbidity; however, it has also resulted in the detection of individuals with an asymptomatic or mild presentation for which early detection via newborn screening has not been proven to alter neurological outcome. …

disease-causing mutation in human fibroblasts and noted significant decreases in TIM23 core protein levels (TIMM50, TIMM17A/B, and TIMM23). Strikingly, TIMM50 deficiency had no impact on the steady-state levels of most of its putative substrates, suggesting that even low levels of a functional …

The natural history of dihydrolipoamide dehydrogenase deficiency in Israel

Ben Pode‐Shakked, Yuval E. Landau, Nava Shaul Lotan, Joshua Manor et autres

Dihydrolipoamide dehydrogenase (DLD) deficiency is an ultra-rare autosomal-recessive inborn error of metabolism, affecting no less than five mitochondrial multienzyme complexes. With approximately 30 patients reported to date, DLD deficiency was associated with three major clinical presentations: an early-onset encephalopathic phenotype with metabolic …

Long-term administration of intravenous Trappsol® Cyclo™ (HP-β-CD) results in clinical benefits and stabilization or slowing of disease progression in patients with Niemann-Pick disease type C1: Results of an international 48-week Phase I/II trial

Reena Kumari Sharma, Caroline Aimee Hastings, Orna Staretz‐Chacham, Julian Raiman et autres

Niemann-Pick disease type C (NPC) is a rare, fatal, pan-ethnic, autosomal recessive lysosomal storage disease characterized by progressive major organ failure and neurodegeneration. Preclinical studies confirmed a critical role of systemically administered hydroxypropyl-β-cyclodextrin (HP-β-CD; Trappsol® Cyclo™) in cholesterol metabolism and homeostasis in …
