  • Research summary

    Genes are like recipes. They tell our cells how to work. The KCNJ11 gene makes a channel, called the Katp channel. The channel is found in the pancreas and the brain. If a person has a spelling change in the KCNJ11 gene, the Katp channel does not work. This causes diabetes very early in life. We call this neonatal diabetes. Many people with neonatal diabetes also have developmental problems. The diabetes can be treated by tablets called sulphonylureas (SUs). SUs help the faulty Katp channels to work. The developmental problems do not improve much with SU treatment. This is because SUs do not stay in the brain for very long. The developmental problems are the biggest challenge for families.

    Memantine is a drug that is already used to treat dementia. It works in the brain. Memantine can act on Katp channels. We do not know if Memantine affects brain Katp channels. If it does, it might be able to help the developmental problems in neonatal diabetes.

    Memantine was first tried in people as a diabetes treatment. However, it had no effect on glucose levels, in people without diabetes or with Type 2 diabetes. In this study, we will give Memantine to adults with neonatal diabetes. We will see if it affects glucose levels. We will also find out if it has any effect on brain function. This will help us understand how Memantine works on Katp channels. The research will help us plan future studies, which will find out if Memantine can treat the developmental problems in neonatal diabetes.
