C22ORF23

Chr 22

chromosome 22 open reading frame 23

Also known as: EVG1, dJ1039K5.6

The protein encoded by this gene functions as a component of the mitochondrial ribosome, specifically participating in mitochondrial protein synthesis. Mutations cause autosomal recessive mitochondrial complex I deficiency, presenting with early-onset neurodegeneration, developmental delay, and multi-organ dysfunction affecting the brain, liver, and skeletal muscle. This gene shows very low constraint against loss-of-function variants in the general population.

Clinical SummaryC22ORF23
Population Constraint (gnomAD)
Low constraint (pLI 0.00) — loss-of-function variants are relatively tolerated in the population.
