Mendeliome v2.0 KGD4 Gene symbol changed from MRPS36 to KGD4 during gene set migration (ENSG00000134056 -> ENSG00000134056)
Mendeliome v1.3302 MRPS36 Krithika Murali gene: MRPS36 was added
gene: MRPS36 was added to Mendeliome. Sources: Literature
Mode of inheritance for gene: MRPS36 was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: MRPS36 were set to PMID: 41018056; 38685873
Phenotypes for gene: MRPS36 were set to Leigh syndrome - MONDO:0009723, MRPS36/KGD4-related
Review for gene: MRPS36 was set to AMBER
Added comment: 3 individuals from 2 unrelated families reported with biallelic MRPS36 variants (current HGNC is KGD4). Gene encodes E4 subunit of OGDHC complex. Individuals present with a phenotype consistent with Leigh syndrome including seizures, hypotonia, dystonia, brain imaging anomalies, persistent lactic acidosis. Cardiomyopathy also reported.

Patient-derived fibroblast studies demonstrates reduced OGDHC enzymatic activity, however, this functional evidence is not gene or variant-specific.
