Pharmacological increases in circulating ketones fail to alleviate the hypertrophic cardiomyopathy present in the Tafazzin knockdown mouse model of Barth syndrome [PDF]

Journal of Pharmacy & Pharmaceutical Sciences
ObjectiveMutations in the tafazzin gene lead to impaired remodeling of cardiolipin, thereby impairing mitochondrial function and causing Barth syndrome (BTHS), a rare X-linked genetic disorder characterized by cardiomyopathy.

Monolysocardiolipins accumulate in Barth syndrome but do not lead to enhanced apoptosis

Journal of Lipid Research, 2005
Barth syndrome (BTHS) is an X-linked recessive disorder that is biochemically characterized by low cellular levels of the mitochondrial phospholipid cardiolipin (CL).

Expanded-access use of elamipretide in a critically ill patient with Barth syndrome [PDF]

Genetics in Medicine Open
Purpose: Barth syndrome (BTHS; OMIM #302060) is a rare disease characterized by cardiolipin abnormalities and cardiomyopathy, intermittent neutropenia and skeletal myopathy among other defects.

Upregulation of the AMPK-FOXO1-PDK4 pathway is a primary mechanism of pyruvate dehydrogenase activity reduction in tafazzin-deficient cells [PDF]

Scientific Reports
Barth syndrome (BTHS) is a rare disorder caused by mutations in the TAFAZZIN gene. Previous studies from both patients and model systems have established metabolic dysregulation as a core component of BTHS pathology.

The Loss of Tafazzin Transacetylase Activity Is Sufficient to Drive Testicular Infertility [PDF]

Journal of Developmental Biology
Barth syndrome (BTHS) is a rare, infantile-onset, X-linked mitochondriopathy exhibiting a variable presentation of failure to thrive, growth insufficiency, skeletal myopathy, neutropenia, and heart anomalies due to mitochondrial dysfunction secondary to ...

Quality of life in Barth syndrome

Therapeutic Advances in Rare Disease, 2022
Introduction: Barth syndrome (BTHS) is a rare X-linked disorder characterized by cardiomyopathy, neutropenia, growth abnormalities, and skeletal myopathy. There have been few studies investigating health-related quality of life (HRQoL) in this population.

Tafazzin deficiency in mouse mesenchymal stem cells promote reprogramming of activated B lymphocytes toward immunosuppressive phenotypes

The FASEB Journal, Volume 36, Issue 8, August 2022., 2022
Abstract Barth Syndrome (BTHS) is a rare X‐linked genetic disorder caused by mutation in the TAFAZZIN gene. Tafazzin (Taz) deficiency in BTHS patients results in an increased risk of infections. Mesenchymal stem cells (MSCs) are well known for their immune‐inhibitory function.

An improved functional assay in blood spot to diagnose Barth syndrome using the monolysocardiolipin/cardiolipin ratio

Journal of Inherited Metabolic Disease, Volume 45, Issue 1, Page 29-37, January 2022., 2022
Abstract Barth syndrome is an X‐linked disorder characterized by cardiomyopathy, skeletal myopathy, and neutropenia, caused by deleterious variants in TAFAZZIN. This gene encodes a phospholipid‐lysophospholipid transacylase that is required for the remodeling of the mitochondrial phospholipid cardiolipin (CL).

Mechano‐energetic aspects of Barth syndrome

Journal of Inherited Metabolic Disease, Volume 45, Issue 1, Page 82-98, January 2022., 2022
Abstract Energy‐demanding organs like the heart are strongly dependent on oxidative phosphorylation in mitochondria. Oxidative phosphorylation is governed by the respiratory chain located in the inner mitochondrial membrane. The inner mitochondrial membrane is the only cellular membrane with significant amounts of the phospholipid cardiolipin, and ...

The lipid environment modulates cardiolipin and phospholipid constitution in wild type and tafazzin‐deficient cells

Journal of Inherited Metabolic Disease, Volume 45, Issue 1, Page 38-50, January 2022., 2022
Abstract Deficiency of the transacylase tafazzin due to loss of function variants in the X‐chromosomal TAFAZZIN gene causes Barth syndrome (BTHS) with severe neonatal or infantile cardiomyopathy, neutropenia, myopathy, and short stature. The condition is characterized by drastic changes in the composition of cardiolipins, a mitochondria‐specific class ...
