Animal and Cellular Models of Barth Syndrome

At present, there are several models of Barth syndrome, each of which has its own unique characteristics. All models show a cardiolipin dysfunction. For any questions or comments, please reach out to erik.lontok@barthsyndrome.org


Research Models

Tafazzin Knockout Mouse (KO) is available via Doug Strathdee, Beatson Institute. Two articles have discussed the Tafazzin KO mouse, the first by Doug Strathdee et al (2015) describes the meiotic challenges in generating the model. The second by Bill Pu et al (2020) characterizes the model and and assesses the impact of AAV-TAZ gene replacement therapy as it relates to BTHS etiology.

Knockdown mouse model (KDown) is available from Jackson Laboratories (B6.Cg-Gt(ROSA)26Sortm37(H1/tetO-RNAi:Taz)Arte/ZkhuJ.

This KDown mouse model was made using a siRNA transgene at the ROSA26 locus to lower the expression of the endogenous mouse tafazzin gene. The model is inducible using doxycycline, and it was made using the proprietary technology of TaconicArtemis, GmbH (Köln, Germany) under contract from BSF.

Kdown mouse review: A critical appraisal of the tafazzin knockdown mouse model of Barth syndrome: what have we learned about pathogenesis and potential treatments? Ren M, Miller PC, Schlame M, Phoon CKL. Am J Physiol Heart Circ Physiol. 2019 Dec 1;317(6):H1183-H1193. doi: 10.1152/ajpheart.00504.2019


Cellular models of Barth syndrome have used shRNAs in rodent cardiac cells to lower tafazzin gene expression in different primary cell lines. The publications for these models are listed below.


Drosophila models of Barth syndrome utilize the imprecise excision of a P element from stock y. Below is a list of publications.


A yeast model of Barth syndrome has also been used extensively. Below is a list of publications.


Human iPS cells and mouse embryonic fibroblasts are also represented in Barth syndrome as shown in the publications below.


A zebra fish model has also been described.
