Changes in these genes cause rare conditions in which Bad breath 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 |
|---|---|---|
| SELENBP1selenium binding protein 1 | Always | In 1 condition |
| CFTRCF transmembrane conductance regulator | Sometimes (5–29%) | In 1 condition |
| SCNN1Asodium channel epithelial 1 subunit alpha | Sometimes (5–29%) | In 1 condition |
| SCNN1Bsodium channel epithelial 1 subunit beta | Sometimes (5–29%) | In 1 condition |
| SCNN1Gsodium channel epithelial 1 subunit gamma | Sometimes (5–29%) | In 1 condition |
| MAT1Amethionine adenosyltransferase 1A | 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.
