Geisinger Autism and Developmental Medicine Institute,Geisinger Health System RCV000489905 SCV000575933 uncertain significance Optic atrophy with or without deafness, ophthalmoplegia, myopathy, ataxia, and neuropathy 2017-04-25 criteria provided, single submitter clinical testing This variant has been identified at an allele frequency of 0.22% in both ExAC overall and in European Americans in ESP; three homozygous individuals have been identified in these databases combined. However, this condition exhibits marked variable expressivity and incomplete penetrance, and compound heterozygous individuals have been reported with milder pathogenic variants. A previously reported patient (Milone, 2009) had a similar presentation to the patient observed in our clinic, but family segregation studies were not done in that case. The patient tested in our clinic presented with fatigue, ataxia, muscle weakness, peripheral neuropathy, ptosis, and external ophthalmoplegia. She did not have optic atrophy at age 51. Her mother had a similar clinical presentation and was deceased. The patient is also an FMR1 premutation carrier. This OPA1 variant was inherited from her father, who at age 74, had no clinical symptoms of neurological or mitochondrial dysfunction, although he had a history of migraines.
