CEDNIK Syndrome, a Rare Neuro-Cutaneous Disorder in an Iranian Patient: Case Report and Review of Specific Neuro-Ichthyotic Syndromes

Cerebral dysgenesis, neuropathy, ichthyosis, and keratoderma (CEDNIK) syndrome is an autosomal recessive neuro-cutaneous disorder characterized by a collection of clinical manifestations, including microcephaly, cerebral dysgenesis, palmoplantar keratoderma, facial dysmorphism, and ichthyosis. The etiology of this condition has been proved to be a homozygous mutation in the SNAP29 gene, which has an essential role in dermatological and neurological manifestations of this syndrome. In this report, we present the first documented Iranian patient with CEDNIK syndrome. So far, only 14 cases of this condition have been reported globally.
