Sarah Leigh edited their review of gene: OGDH: Added comment: After NHS Genomic Medicine Service consideration, the rating of this gene has not been changed and remains amber. This gene is not associated with primary mitochondrial disease. Consensus opinion from the 3 specialist mitochondrial providers.; Changed mode of inheritance: BIALLELIC, autosomal or pseudoautosomal
Sarah Leigh edited their review of gene: OGDH: Added comment: Associated with relevant phenotype in OMIM and as moderate Gen2Phen gene. At least four variants have been reported in four unrelated cases, together with supportive functional studies (PMIDs: 32383294, 36520152).; Changed rating: GREEN
Sarah Leigh Phenotypes for gene: OGDH were changed from Alpha-ketoglutarate dehydrogenase deficiency OMIM:203740; oxoglutaricaciduria MONDO:0008759 to Alpha-ketoglutarate dehydrogenase deficiency, OMIM:203740; oxoglutaricaciduria, MONDO:0008759
Sarah Leigh Phenotypes for gene: OGDH were changed from Alpha-ketoglutarate dehydrogenase deficiency, 203740 (1) to Alpha-ketoglutarate dehydrogenase deficiency OMIM:203740; oxoglutaricaciduria MONDO:0008759
Sarah Leigh Added comment: Comment on list classification: Associated with relevant phenotype in OMIM. Limited association with OGDH-related mitochondrial disorder in Gen2Phen. PMID: 32383294 reported a single biallelic variant in two sibblings. Functional studies were performed on patient fibroblasts, which demonstrated reduced expression of OGDH and a reduced OGDH complex activity in comparison to the wild type. Drosophila models were constructed which supported the role of the OGDH variant in early developmental lethality.
