Summaries for Cerebral Dysgenesis, Neuropathy, Ichthyosis, and Palmoplantar...

NIH Rare Diseases : 53 The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.Orpha Number: 66631Disease definitionCEDNIK syndrome is a neurocutaneaous syndrome characterized by severe developmental abnormalities of the nervous system and aberrant differentiation of the epidermis.EpidemiologyIt has been described so far in seven affected individuals (four boys and three girls) from two consanguineous families.Clinical descriptionClinically, the patients display a unique constellation of clinical signs described with the acronym CEDNIK: CErebral Dysgenesis, Neuropathy, Ichthyosis, and palmoplantar Keratoderma.EtiologyIt is caused by mutations in the SNAP29 gene (22q11.2) which encodes a SNARE protein involved in vesicle fusion.Genetic counselingThe disease is inherited as an autosomal recessive condition.Visit the Orphanet disease page for more resources.

MalaCards based summary : Cerebral Dysgenesis, Neuropathy, Ichthyosis, and Palmoplantar Keratoderma Syndrome, also known as cednik syndrome, is related to cutis laxa, autosomal recessive, type iiia and trichothiodystrophy 4, nonphotosensitive. An important gene associated with Cerebral Dysgenesis, Neuropathy, Ichthyosis, and Palmoplantar Keratoderma Syndrome is SNAP29 (Synaptosome Associated Protein 29), and among its related pathways/superpathways is SNARE interactions in vesicular transport. Affiliated tissues include brain, eye and skin, and related phenotypes are hypertelorism and abnormality of eye movement

Disease Ontology : 12 An autosomal recessive disease that has material basis in homozygous mutation in the SNAP29 gene and characterized by a unique constellation of clinical manifestations including microcephaly, severe neurologic impairment, psychomotor retardation, failure to thrive, facial dysmoprhism, palmoplantar keratoderma and late-onset ichthyosis.

OMIM : 57 CEDNIK (cerebral dysgenesis, neuropathy, ichthyosis, and keratoderma) syndrome refers to a unique constellation of clinical manifestations including microcephaly, severe neurologic impairment, psychomotor retardation, failure to thrive, and facial dysmorphism, as well as palmoplantar keratoderma and late-onset ichthyosis. Brain magnetic resonance imaging (MRI) shows various degrees of cerebral dysgenesis including absence of corpus callosum and cortical dysplasia. The syndrome has been found to be uniformly fatal between the ages of 5 and 12 years (Fuchs-Telem et al., 2011). (609528)

UniProtKB/Swiss-Prot : 75 Cerebral dysgenesis, neuropathy, ichthyosis, and palmoplantar keratoderma syndrome: A neurocutaneous syndrome characterized by cerebral dysgenesis, neuropathy, ichthyosis and palmoplantar keratoderma.
