Summaries for Mental Retardation, Autosomal Dominant 46

About this section
UniProtKB/Swiss-Prot : 72 Mental retardation, autosomal dominant 46: 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. MRD46 patients manifest developmental delay and mild to moderate intellectual disability.

MalaCards based summary : Mental Retardation, Autosomal Dominant 46, is also known as mrd46. An important gene associated with Mental Retardation, Autosomal Dominant 46 is KCNQ5 (Potassium Voltage-Gated Channel Subfamily Q Member 5). Affiliated tissues include eye, and related phenotypes are epileptic encephalopathy and seizure

Disease Ontology : 12 An autosomal dominant non-syndromic intellectual disability that has material basis in heterozygous mutation in the KCNQ5 gene on chromosome 6q14.
