Genes affected
TMCO6 (HGNC:28814): (transmembrane and coiled-coil domains 6) Predicted to enable nuclear import signal receptor activity. Predicted to be involved in protein import into nucleus. Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]
NDUFA2 (HGNC:7685): (NADH:ubiquinone oxidoreductase subunit A2) The encoded protein is a subunit of the hydrophobic protein fraction of the NADH:ubiquinone oxidoreductase (complex 1), the first enzyme complex in the electron transport chain located in the inner mitochondrial membrane, and may be involved in regulating complex I activity or its assembly via assistance in redox processes. Mutations in this gene are associated with Leigh syndrome, an early-onset progressive neurodegenerative disorder. Alternative splicing results in multiple transcript variants.[provided by RefSeq, May 2010]
