Summaries for Riddle Syndrome

About this section
Disease Ontology : 12 An autosomal recessive disease that is characterized by increased radiosensitivity, immunodeficiency, mild motor control and learning difficulties, facial dysmorphism, and short stature that has material basis in homozygous or compound heterozygous mutation in the RNF168 gene on chromosome 3q29.

MalaCards based summary : Riddle Syndrome, also known as radiosensitivity-immunodeficiency-dysmorphic features-learning difficulties syndrome, is related to canavan disease and fanconi anemia, complementation group v, and has symptoms including ataxia and dry skin. An important gene associated with Riddle Syndrome is RNF168 (Ring Finger Protein 168), and among its related pathways/superpathways are Metabolism of proteins and Cell Cycle, Mitotic. Affiliated tissues include skin, bone and eye, and related phenotypes are emotional lability and ataxia

UniProtKB/Swiss-Prot : 75 Riddle syndrome: Characterized by increased radiosensitivity, immunodeficiency, mild motor control and learning difficulties, facial dysmorphism, and short stature. Defects are probably due to impaired localization of TP53BP1 and BRCA1 at DNA lesions.

Wikipedia : 76 RIDDLE syndrome is a rare genetic syndrome. The name is an acronym for Radiosensitivity,... more...
