Abstract
We report the clinical, morphological and molecular features of two patients with autosomal recessive SLC25A4 (ANT1) gene mutations. Furthermore, all previously published cases are reviewed to identify valuable features for future diagnosis. Patients present a common phenotype with exercise intolerance, hyperlactatemia, and hypertrophic cardiomyopathy. Muscle biopsies show wide sub-sarcolemmal mitochondrial aggregates, and increased activities of all respiratory chain complexes. The phenotype of recessive SLC25A4 (ANT1) mutations although rare, is homogenous and easily recognizable and could help orientate the molecular analysis in adults with exercise intolerance associated with hyperlactatemia.
