We have added three new patient information leaflets on glucokinase hyperglycaemia testing in pregnancy to our website, adapted from resources originally produced by the South East Genomic Medicine Service.
Glucokinase hyperglycaemia is a subtype of monogenic diabetes, otherwise known as Maturity Onset Diabetes of the Young (MODY).
A glucokinase (GCK) gene change is like a small spelling mistake in a single gene, which causes mildly raised blood sugar (glucose) levels. Genes provide instructions to help our bodies develop, grow and work. Genes are inherited from our parents.
A GCK gene change is not diabetes. Although it causes a slightly raised blood sugar level, it is not known to cause long term health problems.
Outside of pregnancy a change in the GCK gene does not require treatment or follow up. People with a change in the GCK gene have no greater risk of developing Type 2 diabetes than other members of the general population.
We have three new patient information leaflets as follows:
- GCK testing in pregnancy - patient information leaflet (opens in a new tab) (opens in a new tab)
- GCK gene change - information for family members (opens in a new tab) (opens in a new tab)
- Diagnosed with a change in the GCK gene - patient information leaflet (opens in a new tab) (opens in a new tab)
