Summaries for Mental Retardation, Autosomal Dominant 6, with or Without...

OMIM : 58 MRD6 is an autosomal dominant neurodevelopmental disorder characterized by delayed psychomotor development and intellectual disability of variable severity. Additional features may include seizures, hypotonia, abnormal movements, such as dystonia, and autistic features. Some patients may have structural malformations of cortical development on brain imaging. The phenotype is highly variable and reflects a spectrum of neurodevelopmental abnormalities that range from mild intellectual disability without seizures to an encephalopathy (summary by Platzer et al., 2017). (613970)

MalaCards based summary : Mental Retardation, Autosomal Dominant 6, with or Without Seizures, also known as mental retardation, autosomal dominant 6, is related to autosomal dominant non-syndromic intellectual disability 6. An important gene associated with Mental Retardation, Autosomal Dominant 6, with or Without Seizures is GRIN2B (Glutamate Ionotropic Receptor NMDA Type Subunit 2B). Affiliated tissues include brain, and related phenotypes are seizures and intellectual disability

UniProtKB/Swiss-Prot : 76 Mental retardation, autosomal dominant 6, with or without seizures: A disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. MRD6 additional features may include seizures, hypotonia, abnormal movements, such as dystonia, and autistic features.
