Changes in these genes cause rare conditions in which High blood carbon dioxide level is seen. Most people with this trait have none of those conditions, and a gene on this list says nothing about anyone's own genome.
| Gene | How often it is seen | Conditions |
|---|---|---|
| FDXRferredoxin reductase | Always | In 1 condition |
| NDUFS8NADH:ubiquinone oxidoreductase core subunit S8 | Always | In 1 condition |
| STAC3SH3 and cysteine rich domain 3 | Always | In 1 condition |
| CACNA1Scalcium voltage-gated channel subunit alpha1 S | Often (30–79%) | In 2 conditions |
| RYR1ryanodine receptor 1 | Often (30–79%) | In 1 condition |
| SEL1LSEL1L adaptor subunit of SYVN1 ubiquitin ligase | Often (30–79%) | In 1 condition |
| ACTA1actin alpha 1, skeletal muscle | Sometimes (5–29%) | In 1 condition |
| HACD13-hydroxyacyl-CoA dehydratase 1 | Sometimes (5–29%) | In 1 condition |
| ITGA7integrin subunit alpha 7 | Sometimes (5–29%) | In 1 condition |
| LRP12LDL receptor related protein 12 | Sometimes (5–29%) | In 1 condition |
| MAP3K20mitogen-activated protein kinase kinase kinase 20 | Sometimes (5–29%) | In 1 condition |

| TPM2tropomyosin 2 | Sometimes (5–29%) | In 1 condition |
| TPM3tropomyosin 3 | Sometimes (5–29%) | In 1 condition |
| PHOX2Bpaired like homeobox 2B | Not recorded | In 1 condition |
How often is among people with one of the gene's conditions, the most often across them, as the Human Phenotype Ontology records it. These pages describe traits and the research behind them; they are not a diagnosis, and a doctor or genetic counsellor is the person to ask about symptoms.
