CHIME syndrome, also known as Zunich–Kaye syndrome or Zunich neuroectodermal syndrome, is a rare congenital ichthyosis first described in 1983. The acronym CHIME is based on its main symptoms: colobomas, heart defects, ichthyosiform dermatosis, intellectual disability, and either ear defects or epilepsy. It is a congenital syndrome with only a few cases studied and published.
