Mendeliome v0.10024 OGDHL Melanie Marty gene: OGDHL was added
gene: OGDHL was added to Mendeliome. Sources: Literature
Mode of inheritance for gene: OGDHL was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: OGDHL were set to PMID: 34800363
Phenotypes for gene: OGDHL were set to Neurodevelopmental disorder featuring epilepsy, hearing loss, visual impairment, and ataxia
Review for gene: OGDHL was set to GREEN
Added comment: Nine individuals from eight unrelated families carrying bi-allelic variants in OGDHL with a range of neurological and neurodevelopmental phenotypes including epilepsy, hearing
loss, visual impairment, gait ataxia, microcephaly, and hypoplastic corpus callosum.

Homozygous and compound heterozygous variants reported. Variant types reported include missense, PTCs and a synonymous variant that was shown to affect splicing.

Functional studies with a CRISPR-Cas9-mediated tissue knockout with cDNA rescue system showed that the missense variants result in loss-of-function.

Mendeliome v0.10018 OGDH Zornitza Stark gene: OGDH was added
gene: OGDH was added to Mendeliome. Sources: Literature
Mode of inheritance for gene: OGDH was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: OGDH were set to 32383294
Phenotypes for gene: OGDH were set to Developmental delay; ataxia; seizure; raised lactate
Review for gene: OGDH was set to AMBER
Added comment: Two siblings reported with homozygous missense variant in this gene and global developmental delay, elevated lactate, ataxia and seizure. Fibroblast analysis and modeling of the mutation in Drosophila were used to evaluate pathogenicity of the variant. Note previous report of an individual with developmental delay, hypotonia, and movement disorders and metabolic decompensation and biochemical evidence of OGDH deficiency but genetic testing not done.
