| الوصف: | BACKGROUND: Biallelic loss-of-function NDUFA12 variants have hitherto been linked to mitochondrial complex I deficiency presenting with heterogeneous clinical and radiological features in nine cases only. OBJECTIVES: To fully characterize, both phenotypically and genotypically, NDUFA12-related mitochondrial disease. METHODS: We collected data from cases identified by screening genetic databases of several laboratories worldwide and systematically reviewed the literature. RESULTS: Nine unreported NDUFA12 cases from six pedigrees were identified, with presentation ranging from movement disorder phenotypes (dystonia and/or spasticity) to isolated optic atrophy. MRI showed basal ganglia abnormalities (n = 6), optic atrophy (n = 2), or was unremarkable (n = 1). All carried homozygous truncating NDUFA12 variants, three of which are novel. CONCLUSIONS: Our case series expands phenotype–genotype correlations in NDUFA12-associated mitochondrial disease, providing evidence of intra- and inter-familial clinical heterogeneity for the same variant. It confirms NDUFA12 variants should be included in the diagnostic workup of Leigh/Leigh-like syndromes – particularly with dystonia – as well as isolated optic atrophy. |
