The cardinal features of Barth syndrome are cardiac and skeletal myopathy and neutropaenia, reported in the initial description of this condition by Barth et al. (J Neurol Sci 62:327–355) in 1983. Many features of the Barth phenotype have been described but there is no published comment on the facial appearance of these boys, which is consistent and characteristic of this condition.
