Expanding the phenotypic spectrum of BCS1L-related mitochondrial disease
Objective: To delineate the full phenotypic spectrum of BCS1L-related disease, provide better understanding of the genotype–phenotype correlations and identify reliable prognostic disease markers. Methods: We performed a retrospective multinational cohort study of previously unpublished patients followed in 15 centres from 10 countries. Patients with confirmed biallelic pathogenic BCS1L variants w
