Changes in these genes cause rare conditions in which High blood magnesium levels 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 |
|---|---|---|
| CASRcalcium sensing receptor | Always | In 1 condition |
| CLDN10claudin 10 | Always | In 1 condition |
| GNA11G protein subunit alpha 11 | Always | In 1 condition |
| ALDOBaldolase, fructose-bisphosphate B | Sometimes (5–29%) | In 1 condition |
| CLCNKBchloride voltage-gated channel Kb | Sometimes (5–29%) | In 1 condition |
| SLC12A3solute carrier family 12 member 3 | Sometimes (5–29%) | In 1 condition |
| AP2S1adaptor related protein complex 2 subunit sigma 1 | 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.
