This gene was submitted as "PEO1" by two experts, which likely corresponds to this HGNC-approved symbol. Illumina source has this gene as both dominant (for Progressive External Ophthalmoplegia with Mitochondrial DNA Deletions) and recessive (for Mitochondrial Membrane Protein-Associated Neurodegeneration and Mitochondrial DNA Depletion Syndrome).Created: 1 Jul 2015, 2:36 p.m.
