Coenzyme Q10 Supplementation in a Child with Biallelic COQ8A Variants: A Case Report.
Pathogenic variants in COQ8A cause a rare form of primary coenzyme Q10 (CoQ10) deficiency that can lead to childhood-onset cerebellar ataxia and developmental delay. However, reports of pediatric cases remain limited, and evidence regarding therapeutic response to CoQ10 supplementation in children is still scarce. We report a 7-year-old boy with compound heterozygous COQ8A variants who presented with progressive cerebellar ataxia and intellectual disability. Oral CoQ10 supplementation was initiated at a dose of 10 mg/kg/day after institutional ethics approval. During 1 year of treatment, the Scale for the Assessment and Rating of Ataxia (SARA) score improved from 17 to 9, and serum CoQ10 concentration increased from 622 to 9.100 ng/mL. Mild cognitive improvement was also observed, with the intelligence quotient increasing from 53 to 64. Brain MRI demonstrated radiological stabilization of cerebellar atrophy. No adverse effects related to CoQ10 supplementation were observed throughout the treatment period. This case demonstrates the clinical benefit and safety of CoQ10 supplementation in pediatric-onset COQ8A-related ataxia. Early genetic diagnosis and timely initiation of CoQ10 therapy may lead to meaningful neurological improvement and stabilization of disease progression in affected children.
Ferroptosis susceptibility in primary coenzyme Q10 deficiency: Cellular insights from patient fibroblasts and clinical course of six individuals.
Primary coenzyme Q10 (CoQ10) deficiency is a group of mitochondrial disorders caused by pathogenic variants of genes involved in CoQ10 biosynthesis. Although some patients respond to oral CoQ10 supplementation, the pathophysiology remains poorly understood. Ferroptosis, a form of iron-dependent cell death driven by lipid peroxidation, is suppressed by reduced CoQ10via ferroptosis suppressor protein 1 (FSP1). However, its involvement in primary CoQ10 deficiency has not yet been studied using patient-derived cells. We reported six patients from three families and investigated ferroptosis susceptibility in fibroblasts from three representative patients: one with COQ2 variants and two with COQ4 variants. Fibroblasts with COQ2 variants showed increased vulnerability to ferroptosis inducers, plasma membrane lipid peroxidation. In contrast, fibroblasts with COQ4 variants exhibited only mild changes. Notably, susceptibility to ferroptosis remained unchanged after increasing intracellular CoQ10 levels. Despite this persistent ferroptosis sensitivity in vitro, the COQ2 patient exhibited significant clinical improvement following CoQ10 supplementation. These findings suggest that ferroptosis may contribute to cellular vulnerability in primary CoQ10 deficiency but may not be the primary driver of renal and neurological symptoms. Our results highlight a complex interplay between CoQ10 biosynthesis, ferroptosis defense, and therapeutic response, warranting further investigation of subcellular CoQ10 distribution and ferroptosis-related mechanisms.

Mitochondrial Dysfunctions in Human Primary Coenzyme Q10 Deficiencies.
Coenzyme Q10 (CoQ10) is an essential lipid-soluble molecule that plays a central role in mitochondrial energy production as a mobile electron carrier. In addition to its bioenergetic function, CoQ10 participates in antioxidant defense, redox homeostasis, lipid and nucleotide metabolism, and mitochondrial quality control. Primary CoQ10 deficiencies are rare inherited mitochondrial disorders caused by pathogenic variants in nuclear genes involved in CoQ10 biosynthesis. These defects lead to reduced CoQ10 levels and impaired mitochondrial functions. Clinically, primary CoQ10 deficiencies display remarkable phenotypic heterogeneity, ranging from isolated organ involvement, notably renal or cerebellar disease, to severe multisystemic disorders affecting the nervous system, skeletal muscle, heart, and other organs. Disease onset spans from the antenatal period to adulthood, and clinical severity varies widely, even among patients carrying variants in the same gene. This diversity cannot be fully explained by defective ATP production alone. Growing evidence indicates that disruption of non-bioenergetic functions of CoQ10, including oxidative stress regulation and CoQ-dependent metabolic pathways, contributes significantly to disease pathophysiology and tissue vulnerability. In this review, we summarize current knowledge on CoQ10 biology, biosynthesis, and the clinical spectrum of primary CoQ10 deficiencies, and we discuss emerging mechanisms linking CoQ10 depletion to mitochondrial dysfunctions and human diseases.
Intermittent ketogenic fasting with medium-chain triglycerides improves ataxia in COQ8A-related coenzyme Q10 deficiency: A case report.
Mutations in COQ8A cause primary coenzyme Q10 deficiency, which can present clinically heterogeneously: Symptoms range from cerebellar ataxia, epilepsy, encephalomyopathy, macular degeneration to nephropathy. High-dose coenzyme Q10 supplementation is widely used, yet there is little evidence on complementary strategies, particularly for non-epileptic features such as cerebellar ataxia. We report a 46-year-old female with genetically confirmed COQ8A-related coenzyme Q10 (CoQ10) deficiency, presenting with ataxia and epilepsy characterized by myoclonic and bilateral tonic-clonic seizures, who participated in a clinical protocol of ketogenic intermittent fasting, a method of intermittent fasting combined with medium-chain triglycerides (MCT) primarily designed for seizure management. The patient followed a 16:8 intermittent fasting regime combined with MCT intake for three months, followed by three months of all-alone intermittent fasting. Routine blood markers and brain MRI, including diffusion imaging were obtained before and after ketogenic fasting. During the study protocol, while no seizure reduction in myoclonic seizures could be observed, ataxia - quantified by the Scale for the Assessment and Rating of Ataxia (SARA) - improved significantly from 8.5 to 6.0 during the interventions. MRI showed a trend suggesting improved cerebellar microstructural integrity. This case highlights the potential of ketogenic intermittent fasting as an adjunct therapy for mitochondrial ataxia. Ketogenic intermittent fasting was associated with clinically meaningful improvement of ataxia in a patient with COQ8A-related CoQ10 deficiency, suggesting that ketogenic dietary strategies may represent a promising adjunct therapeutic approach for mitochondrial ataxia. Future research should assess this intervention in larger patient cohorts to confirm its potential benefits.
