Gastrointestinal neuromuscular disease v2.0 POLG Gene migrated from ENSG00000140521 to ENSG00000140521 (gene set migration)
Gastrointestinal neuromuscular disease v0.66 POLG Zornitza Stark Marked gene: POLG as ready
Gastrointestinal neuromuscular disease v0.66 POLG Zornitza Stark Gene: polg has been classified as Green List (High Evidence).
Gastrointestinal neuromuscular disease v0.66 POLG Zornitza Stark Phenotypes for gene: POLG were changed from Mitochondrial DNA depletion syndrome 4B (MNGIE type), 613662 to Mitochondrial DNA depletion syndrome 4A (Alpers type), MIM# 203700
Gastrointestinal neuromuscular disease v0.65 POLG Zornitza Stark Publications for gene: POLG were set to
Gastrointestinal neuromuscular disease v0.64 POLG Zornitza Stark reviewed gene: POLG: Rating: GREEN; Mode of pathogenicity: None; Publications: 22006280; Phenotypes: Mitochondrial DNA depletion syndrome 4A (Alpers type), MIM# 203700; Mode of inheritance: BIALLELIC, autosomal or pseudoautosomal
Gastrointestinal neuromuscular disease v0.28 POLG2 Bryony Thompson Marked gene: POLG2 as ready
Gastrointestinal neuromuscular disease v0.28 POLG2 Bryony Thompson Gene: polg2 has been classified as Red List (Low Evidence).
Gastrointestinal neuromuscular disease v0.28 POLG2 Bryony Thompson gene: POLG2 was added
gene: POLG2 was added to Gastrointestinal neuromuscular disease. Sources: Expert list
Mode of inheritance for gene: POLG2 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Publications for gene: POLG2 were set to 21555342; 27775730
Phenotypes for gene: POLG2 were set to Progressive external ophthalmoplegia with mitochondrial DNA deletions, autosomal dominant 4 MIM#610131
Review for gene: POLG2 was set to RED
Added comment: 3 unrelated cases have been reported with gastrointestinal symptoms and 3 different heterozygous missense (L153V, R369G, S423Y). All 3 missense are too common in gnomAD v2.1 for a dominant disease and biochemical assays demonstrated normal function for all expect R369G variants had reduced stimulation of processivity and decreased affinity for the catalytic subunit.
