  Barth Syndrome - X-linked Cardiomyopathy and Neutropenia
Interestingly, although 3-methylglutaconic acid is known as an intermediate in the catabolism of the amino acid L-leucine, the excess 3-methylglutaconic acid in Barth syndrome appears to arise independent of the metabolism of leucine.
However, some severely affected Barth patients have no biochemical or histological evidence of mitochondrial dysfunction, and certain features of the syndrome, such as growth retardation and cyclic neutropenia, are not easily explained by the relatively mild degree of mitochondrial impairment in Barth syndrome.
Nevertheless, the incidence of Barth syndrome is almost certainly underestimated because infants and children who die acutely with a dilated cardiomyopathy are often assumed to have a viral myocarditis and may not always have a full metabolic evaluation.

Since some Barth Syndrome patients have abnormally shaped mitochondria (see mitochondria diagrams in the Questions section) in some of their tissues, it is possible that the BTHS proteins have a role in the remodeling of the mitochondrial membrane.
Note: There is another (allelic) version of Barth Syndrome that is called,"isolated noncompaction of the left ventricular myocardium (INVM)." This disorder is also caused by alterations in the BTHS gene, but only involves the heart defect, and not the other symptoms normally associated with Barth Syndrome (10).
