Genes affected

COX8C (HGNC:24382): (cytochrome c oxidase subunit 8C) Predicted to be involved in mitochondrial electron transport, cytochrome c to oxygen. Located in mitochondrion. [provided by Alliance of Genome Resources, Apr 2022]

COX8C links:

UNC79 (HGNC:19966): (unc-79 homolog, NALCN channel complex subunit) The NALCN channel is responsible for Na(+) leak currents. The protein encoded by this gene, along with UNC80, is an accessory subunit of the NALCN channel that contributes to the Ca(2+) sensitivity of the channel. [provided by RefSeq, Sep 2016]
