CEDNIK syndrome; Cerebral dysgenesis, neuropathy, ichthyosis, and palmoplantar keratoderma syndrome
Description
CEDNIK (Cerebral dysgenesis, neuropathy, ichthyosis and keratoderma) syndrome is a rare condition that shows severe developmental failure of the nervous system and the epidermis. Clinical manifestations include microcephaly, cerebral dysgenesis, facial dysmorphism, palmoplantar keratoderma, and ichthyosis. Decreased expression of SNAP29, a member of the SNARE family of proteins, is linked to abnormal lamellar granule maturation and abnormal epidermal differentiation.

Title
A mutation in SNAP29, coding for a SNARE protein involved in intracellular trafficking, causes a novel neurocutaneous syndrome characterized by cerebral dysgenesis, neuropathy, ichthyosis, and palmoplantar keratoderma.
