Summaries for Mental Retardation, Autosomal Dominant 56

About this section
Disease Ontology : 12 A syndromic intellectual disability characterized by global developmental delay, intellectual disability and in most cases hypotonia, delayed walking, poor fine motor skills, and poor or absent speech that has material basis in heterozygous mutation in the CLTC gene on chromosome 17q23.

MalaCards based summary : Mental Retardation, Autosomal Dominant 56, also known as autosomal dominant mental retardation 56, is related to cataract 8, multiple types and parkinson disease, late-onset. An important gene associated with Mental Retardation, Autosomal Dominant 56 is CLTC (Clathrin Heavy Chain), and among its related pathways/superpathways are Vesicle-mediated transport and Delta508-CFTR traffic / ER-to-Golgi in CF. Affiliated tissues include brain, and related phenotypes are seizure and intellectual disability

UniProtKB/Swiss-Prot : 72 Mental retardation, autosomal dominant 56: A form of mental retardation, a disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period.
