9 genes linked to Postprandial hyperglycemia

Changes in these genes cause rare conditions in which Postprandial hyperglycemia 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
INSRinsulin receptor	Very often (80–99%)	In 4 conditions
CACNA1Scalcium voltage-gated channel subunit alpha1 S	Often (30–79%)	In 2 conditions
GABRA3gamma-aminobutyric acid type A receptor subunit alpha3	Often (30–79%)	In 1 condition
GYS2glycogen synthase 2	Often (30–79%)	In 2 conditions
KCNE3potassium voltage-gated channel subfamily E regulatory subunit 3	Often (30–79%)	In 1 condition
KCNJ18potassium inwardly rectifying channel subfamily J member 18	Often (30–79%)	In 1 condition
SCN4Asodium voltage-gated channel alpha subunit 4	Often (30–79%)	In 1 condition
SHPKsedoheptulokinase	Often (30–79%)	In 1 condition
SLC2A2solute carrier family 2 member 2	Often (30–79%)	In 2 conditions

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.
