Zornitza Stark gene: MTERF3 was added gene: MTERF3 was added to Intellectual disability syndromic and non-syndromic. Sources: Literature Mode of inheritance for gene: MTERF3 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: MTERF3 were set to 40543543 Phenotypes for gene: MTERF3 were set to Mitochondrial disease (MONDO:0044970), MTERF3-related Review for gene: MTERF3 was set to AMBER Added comment: Two individuals reported from unrelated families, presenting with DD/ID, intermittent hypoglycaemia and metabolic acidosis. Genetic testing identified compound heterozygous variants c.635dup p.(Asn212Lysfs*7) and c.1055C > T p.(Pro352Leu) in Patient 1, and a homozygous variant c.943A > Gp.(Met315Val) in Patient 2. Patient's fibroblasts and MTERF3 knockdown cells showed impaired mitochondrial respiration and reduced levels of OXPHOS complexes I, III, and IV. Transcription of MT-ND5, ND6, COII, and COIII was reduced, while other mitochondrial genes were upregulated. Wild-type MTERF3 expression restored these defects, but the variant Pro352Leu from patient failed to rescue mitochondrial dysfunction. Sources: Literature |
