Question: Is 6q24-related transient neonatal diabetes mellitus inherited ?
Answer: Most cases of 6q24-related transient neonatal diabetes mellitus are not inherited, particularly those caused by paternal uniparental disomy. In these cases, genetic changes occur as random events during the formation of reproductive cells (eggs and sperm) or in early embryonic development. Affected people typically have no history of the disorder in their family. Sometimes, the genetic change responsible for 6q24-related transient neonatal diabetes mellitus is inherited. For example, a duplication of genetic material on the paternal chromosome 6 can be passed from one generation to the next. When 6q24-related transient neonatal diabetes mellitus is caused by ZFP57 gene mutations, it is inherited in an autosomal recessive pattern. Autosomal recessive inheritance means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.
