The test involves having a blood sample taken from your arm. Then, the DNA (or genetic information) is removed from some of the blood cells and studied at the University of Copenhaguen to see whether or not you have an alteration in one of the known genes that cause MODY. The remaining DNA is then stored in a freezer.
In around 20% of the patients the mutation in one of the known MODY genes may not be found, and since there are more MODY genes to be found, in the case your first genetic study did not show any mutation, your stored sample may be retested as new MODY genes are discovered.
The blood sample you provide will ONLY be tested for changes in known MODY genes. Your blood sample will not be tested for conditions other than diabetes.
