Developmental delay, epilepsy, and neonatal diabetes

DEND syndrome (developmental delay, epilepsy, and neonatal diabetes mellitus) is a dominant disorder and a special form of permanent neonatal diabetes mellitus (PNDM) caused by specific KCNJ11 mutations. It is characterized by additional neurological symptoms as delayed cognitive development and epilepsy.
