Mitochondrial DNA maintenance disorder
Gene: TOP3AComment on list classification: Update recieved from Carl Fratter on 24th July 2019 on behalf of the NHSE GMS Mitochondrial Specialist Group: After overall review by the GMS mitochondrial specialist test group, this gene was agreed to be Green on this panel, as the Newcastle team are aware of another unrelated case, and it was made Green with agreement from the group on the Possible mitochondrial disorder - nuclear genes gene panel (code 539, version 0.206).Created: 24 Jul 2019, 9:28 a.m. | Last Modified: 24 Jul 2019, 9:28 a.m.
Panel Version: 0.11
Comment on list classification: The evidence underlying this gene and mitochondrial DNA maintenance disorders was discussed on the NHSE GMS Mitochondrial Specialist Group Meeting call on 25th February 2019. It was agreed that this gene should be demoted from Green to Amber on this panel due to only a single case (compound heterozygous for variants in this gene) being reported Progressive external ophthalmoplegia with mitochondrial DNA deletions.Created: 25 Feb 2019, 4:42 p.m.
