Phospholipid abnormalities in children with Barth syndrome

Journal of the American College of Cardiology, 2003
We sought to identify characteristic lipid abnormalities in patients with Barth syndrome (BTHS) and to correlate the lipid profile to phenotype and genotype.Barth syndrome typically includes cardiomyopathy, skeletal myopathy, neutropenia, growth retardation, and 3-methylglutaconic aciduria, and it is commonly associated with mutations in the tafazzin ...

Stimulating the sir2–spargel axis rescues exercise capacity and mitochondrial respiration in a Drosophila model of Barth syndrome

Disease Models & Mechanisms, 2022
Cardiolipin (CL) is a phospholipid required for proper mitochondrial function. Tafazzin remodels CL to create highly unsaturated fatty acid chains. However, when TAFAZZIN is mutated, CL remodeling is impeded, leading to mitochondrial dysfunction and the ...

Extended recovery of cardiac function after severe infantile cardiomyopathy presentation of Barth syndrome

JIMD Reports, 2022
Cardiomyopathy is the most common presenting feature of Barth syndrome, often presenting in infancy with severe heart failure and cardiac dysfunction. Historically, affected infants commonly died early after presentation, sometimes before a diagnosis of ...

Generation of a homozygous TAZ knockout hESCs line by CRISPR/Cas9 system

Stem Cell Research, 2022
Tafazzin (TAZ), a mitochondrial transacylase located on chromosome X, is required for the production of the mitochondrial phospholipid cardiolipin. Mutations occurring in the TAZ gene will lead to Barth syndrome, an X-linked recessive disease generally ...

Deficiency in Cardiolipin Reduces Doxorubicin-Induced Oxidative Stress and Mitochondrial Damage in Human B-Lymphocytes. [PDF]

PLoS ONE, 2016
Cardiolipin (CL) is an inner mitochondrial membrane phospholipid which plays an important role in mitochondrial function. Perturbation in CL biosynthesis alters mitochondrial bioenergetics causing a severe genetic disorder commonly known as Barth ...

Current Knowledge on the Role of Cardiolipin Remodeling in the Context of Lipid Oxidation and Barth Syndrome

Frontiers in Molecular Biosciences, 2022
Barth syndrome (BTHS, OMIM 302060) is a genetic disorder caused by variants of the TAFAZZIN gene (G 4.5, OMIM 300394). This debilitating disorder is characterized by cardio- and skeletal myopathy, exercise intolerance, and neutropenia.

Re-Expression of Tafazzin Isoforms in TAZ-Deficient C6 Glioma Cells Restores Cardiolipin Composition but Not Proliferation Rate and Alterations in Gene Expression

Frontiers in Genetics, 2022
Tafazzin—an acyltransferase—is involved in cardiolipin (CL) remodeling. CL is associated with mitochondrial function, structure and more recently with cell proliferation. Various tafazzin isoforms exist in humans.

Mitochondrial dysfunctions in barth syndrome [PDF]

IUBMB Life, 2019
ABSTRACTBarth syndrome (BTHS) is a rare multisystemic genetic disorder caused by mutations in the TAZ gene. TAZ encodes a mitochondrial enzyme that remodels the acyl chain composition of newly synthesized cardiolipin, a phospholipid unique to mitochondrial membranes.

Elamipretide for Barth syndrome cardiomyopathy: gradual rebuilding of a failed power grid

, 2021
Barth syndrome is a rare and potentially fatal X-linked disease characterized by cardiomyopathy, skeletal muscle weakness, growth delays, and cyclic neutropenia.
