Abstract

OPA1 is highly expressed in retina and optic nerve. OPA1 mutations were first identified in patients with non-syndromic autosomal dominant optic atrophy. Recently, OPA1 mutations were detected in a multisystemic disorder which has optic atrophy as the core clinical feature and multiple mitochondrial DNA (mtDNA) deletions in muscle. We report a patient with a multisystemic disorder and multiple muscle mtDNA deletions, carrying an in-frame deletion in OPA1 in the absence of optic atrophy. This patient provides evidence that optic atrophy is not the main clinical manifestation of OPA1-related disorders. OPA1 analysis should be considered in mitochondrial disorders despite the lack of optic atrophy.
