Transient neonatal diabetes mellitus (TNDM) is a form of neonatal diabetes presenting at birth that is not permanent.

This disease is considered to be a type of maturity onset diabetes of the young (MODY).

This condition has to do with genetics and is often associated with having an added Chromosome 7 gene (mostly from the paternal side).

[citation needed] The form on chromosome 6 can involve imprinting.
