Whole exome sequencing of a patient with Leigh-like syndrome identified homozygous protein-truncating variants in TIMMDC1 which was predicted to truncate 61 amino acids at the C-terminus. Functional studies demonstrated a hypomorphic impact of the variant on CI assembly. However, the mutant protein could still rescue CI assembly in TIMMDC1 knockout cells.

Data suggest that the hub genes NADH:ubiquinone oxidoreductase subunit B5 (NDUFB5), translocase of inner mitochondrial membrane domain containing 1 (TIMMDC1), and voltage-dependent anion channel 3 (VDAC3) might serve as potential biomarkers for diagnosis and/or therapeutic targets for precise treatment of septic cardiomyopathy (SC) .

Findings suggest that TIMMDC1 may play an important role in human gastric cancer development, and its underlying mechanism is not only associated with mitochondrial complex I inhibition and reduced mitochondrial respiration, but is also associated with reduced glycolysis activity and the AKT/GSK3beta/beta-catenin signaling pathways.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
