3 genes linked to Periodic hyperkalemic paralysis

Changes in these genes cause rare conditions in which Periodic hyperkalemic paralysis 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.

GeneHow often it is seenConditions
SCN4Asodium voltage-gated channel alpha subunit 4Very often (80–99%)In 2 conditions
KCNJ2potassium inwardly rectifying channel subfamily J member 2Sometimes (5–29%)In 1 condition
KCNJ5potassium inwardly rectifying channel subfamily J member 5Sometimes (5–29%)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.
