Fetal anomalies v1.964 POLG2 Arina Puzriakova Phenotypes for gene: POLG2 were changed from Mitochondrial DNA depletion syndrome 16 (hepatic type), OMIM:618528; Mitochondrial DNA depletion syndrome 16 (hepatic type), MONDO:0032799; Progressive external ophthalmoplegia with mitochondrial DNA deletions, autosomal dominant 4, OMIM:610131; Progressive external ophthalmoplegia with mitochondrial DNA deletions, autosomal dominant 4, MONDO:0012415 to Mitochondrial DNA depletion syndrome syndrome 16 (hepatic type), OMIM:618528; Mitochondrial DNA depletion syndrome 16B (neuroophthalmic type), OMIM:619425; Progressive external ophthalmoplegia with mitochondrial DNA deletions, autosomal dominant 4, OMIM:610131
Fetal anomalies v1.836 POLG2 Arina Puzriakova Tag for-review was removed from gene: POLG2.
Fetal anomalies v1.836 POLG2 Arina Puzriakova commented on gene: POLG2: The rating of this gene has been updated following NHS Genomic Medicine Service approval.
Fetal anomalies v1.835 POLG2 Arina Puzriakova Source Expert Review Green was added to POLG2.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Fetal anomalies v1.508 POLG2 Arina Puzriakova Phenotypes for gene: POLG2 were changed from Mitochondrial DNA depletion syndrome 16 (hepatic type); Progressive external ophthalmoplegia with mitochondrial DNA deletions, autosomal dominant 4 to Mitochondrial DNA depletion syndrome 16 (hepatic type), OMIM:618528; Mitochondrial DNA depletion syndrome 16 (hepatic type), MONDO:0032799; Progressive external ophthalmoplegia with mitochondrial DNA deletions, autosomal dominant 4, OMIM:610131; Progressive external ophthalmoplegia with mitochondrial DNA deletions, autosomal dominant 4, MONDO:0012415
Fetal anomalies v1.496 POLG2 Arina Puzriakova Classified gene: POLG2 as Amber List (moderate evidence)
Fetal anomalies v1.496 POLG2 Arina Puzriakova Added comment: Comment on list classification: New gene added by Rhiannon Mellis (GOSH). Following curation and clinical review it has been agreed that the associated phenotype is fetally-relevant and therefore this gene should be promoted to Green at the next GMS panel update (added 'for-review' tag)
Fetal anomalies v1.496 POLG2 Arina Puzriakova Gene: polg2 has been classified as Amber List (Moderate Evidence).
Fetal anomalies v1.495 POLG2 Arina Puzriakova Tag for-review tag was added to gene: POLG2.
Fetal anomalies v1.205 POLG2 Rhiannon Mellis gene: POLG2 was added
gene: POLG2 was added to Fetal anomalies. Sources: Expert list
Mode of inheritance for gene: POLG2 was set to BOTH monoallelic and biallelic (but BIALLELIC mutations cause a more SEVERE disease form), autosomal or pseudoautosomal
Phenotypes for gene: POLG2 were set to Mitochondrial DNA depletion syndrome 16 (hepatic type); Progressive external ophthalmoplegia with mitochondrial DNA deletions, autosomal dominant 4
Review for gene: POLG2 was set to GREEN
Added comment: This gene and phenotype were reviewed during meetings at Great Ormond Street hospital in October 2020. This gene has a Green evidence rating on at least one other related PanelApp panel. Clinical review and curation was performed by Lyn Chitty, Rhiannon Mellis, and Richard Scott. Outcome of review: Confirmed that phenotype is fetally-relevant: add to the Fetal anomalies panel as a Green gene.
