Fatigue and endurance remain critical challenges for our community of affected individuals. On September 24, 2021, Dr. Todd Cade (Duke U.) joined us for a conversation on the role and impact of resistance training in ameliorating these issues. We invited study participants as well as affected individuals that have engaged in resistance training resources and efforts to discuss their firsthand experience with this therapy.

Inconsistencies in the FDA’s approach to operationalizing the 21st Century Cures Act stand to treat individuals with Barth syndrome qualitatively differently from those with other diseases, such as Alzheimer’s, and points to a critical need for consistent application of patient perspectives in the review process across agency divisions and regulators.

The Severe Chronic Neutropenia International Registry (SCNIR or Registry) maintains a database on the infectious complications and other serious health events for patients enrolled in the Registry. Since the epidemic began in February 2020, 15 patients with positive antibody tests have reported to the Seattle office about their illness and complications. Most of the cases occurred between February 2020 and February 2021, with the highest frequency in September to November 2020. The age range was broad, 2-62 years; the average was 29 years. There were 9 females and 8 males.

Read the special feature article in the Autumn 2019 Gene Therapy edition of Rare Revolution Magazine. Driven by a community committed to finding a cure for Barth syndrome and two decades of research, the potential for realization of gene therapy for Barth syndrome - and the complexities of making it work - are at the forefront of the organization's mission today.

The Human Tafazzin Gene Variants Database has been updated. Note that there are separate tabs for Pathogenic/Likely Pathogenic, Variants of Unknown Significance (VUS), Benign.

This database includes mutations and variants even when they are repeated. However, they must be present in unrelated families. The aim is to provide information to physicians as to whether or not a mutation found in a patient has been seen before in other affected individuals. The database is also used by researchers. Mutations and variants listed come from the literature, from direct submission by laboratories, and from direct submission by affected families. Pathogenicity of many of the mutations is confirmed by monolysocardiolipin/ cardiolipin assay; mRNA study has characterized some of the splicing variants; large evolutionary alignments provide information about amino acid conservation; family information regarding de novo mutations is included; the functional effects of human TAZ mutations modeled in yeast are included. There are links to the PubMed abstracts of references.


The Barth Syndrome Foundation, Inc. (BSF) and its international affiliates announce the availability of funding for basic science and clinical research on the natural history, biochemical basis, and treatment of Barth syndrome.
