Summaries for Neurodevelopmental Disorder with or Without Hyperkinetic...

OMIM : 56 NDHMSR is an autosomal recessive neurodevelopmental disorder characterized by severely delayed psychomotor development, severe intellectual disability, and involuntary movements, including stereotypic movements, spasticity, and dystonia. Affected individuals are are usually unable to walk independently and have poor or absent speech. Some patients have intractable seizures (summary by Lemke et al., 2016). (617820)

MalaCards based summary : Neurodevelopmental Disorder with or Without Hyperkinetic Movements and Seizures, Autosomal Recessive, also known as ndhmsr, is related to grin1-related neurodevelopmental disorder. An important gene associated with Neurodevelopmental Disorder with or Without Hyperkinetic Movements and Seizures, Autosomal Recessive is GRIN1 (Glutamate Ionotropic Receptor NMDA Type Subunit 1). Affiliated tissues include eye, and related phenotypes are cerebral cortical atrophy and hypoplasia of the corpus callosum

UniProtKB/Swiss-Prot : 73 Neurodevelopmental disorder with or without hyperkinetic movements and seizures, autosomal recessive: An autosomal recessive neurodevelopmental disorder characterized by severe mental retardation and psychomotor developmental delay, involuntary and stereotypic movements, spasticity, and inability to walk without support. Intractable seizures manifest in some patients.
