Neonatal diabetes mellitus (NDM), also known as congenital diabetes or diabetes of infancy, is a rare form of diabetes that presents in the first six months of life. Unlike more common forms of diabetes, which are typically polygenic or related to environmental factors, NDM is often associated with monogenic defects. Monogenic diabetes is caused by mutations in a single gene and accounts for a small percentage of diabetes cases.
