Encephalopathy-hypertrophic cardiomyopathy-renal tubular disease syndrome
MONDO:0013840Encephalopathy-hypertrophic cardiomyopathy-renal tubular disease syndrome is a rare mitochondrial disease due to a defect in coenzyme Q10 biosynthesis that manifests with a broad spectrum of signs and symptoms which may include: neonatal lactic acidosis, global developmental delay, tonus disorder, seizures, reduced spontaneous movements, ventricular hypertrophy, bradycardia, renal tubular dysfunction with massive lactic acid excretion in urine, severe biochemical defect of respiratory chain complexes II/III when assayed together and deficiency of coenzyme Q10 in skeletal muscle. Cerebral and cerebellar atrophy can be seen on magnetic resonance imaging and multiple choroid plexus cysts and symmetrical hyperechoic signal alterations in basal ganglia have been observed on ultrasound.
Also known as: coenzyme Q10 deficiency, primary, type 5, COQ10D5, coenzyme Q10 deficiency, primary, 5

New drug aims to tame hard-to-control seizures in rare mitochondrial disorders
Disease control Stopped earlyThis study tested a drug called vatiquinone in 68 people with mitochondrial disease and epilepsy that doesn't respond to standard treatments. Participants were randomly assigned to receive either vatiquinone or a placebo for 24 weeks to see if the drug could reduce the number of …

Could a simple blood test track nerve damage? a study investigates NT-3 levels in neuropathy.
Knowledge-focused Stopped earlyThis study measures levels of a protein called NT-3 in the blood of people with peripheral neuropathy or Charcot-Marie-Tooth disease. Researchers will compare these levels with measures of muscle strength, mobility, and daily function. The goal is to see whether NT-3 levels corre…
