The signs and symptoms of KIF1A-related disorder can vary greatly from one person to another depending on the specific variation in the gene that is present, the inheritance pattern and other factors. As truncation mutations result in similar phenotypes as gain-of-function missense mutations, it is hypothesized that a lack of GluN2A expression due to truncation and haploinsufficiency is compensated by an increase of GluN2B expression. H, Hu P, Galat E, Torres-Platas SG, Boudreau-Pinsonneault C, O'Leary LA, Galat V, However, de novo mutations appear to cluster in functionally important S1 and S2 domains as well as transmembrane domains and usually result in rather severe phenotypes. The assembly of this heterotetrameric receptor follows a specific temporo-spatial expression pattern. Sensory neurons are the nerves cells that respond to stimuli like pain or temperature.

For all mutations investigated so far, the observed pathomechanism resulted in a gain of NMDA receptor function by either loss of Zn2+ inhibition or increase of glutamate sensitivity or reduction of Mg2+ block. Quincy, MA 02169 Genetic counseling is recommended for affected individuals and their families. Neurologic examination helps identify the specific features affecting a person. Phenotypes. GRIN1 -related neurodevelopmental disorder ( GRIN1 -NDD) is characterized by mild-to-profound developmental delay / intellectual disability in all affected individuals. Too much signal can over-excite the brain, which impacts how connections are made and might* result in seizures. Epilepsy aphasia spectrum: This spectrum shows phenotypic overlap in particular to CSWS and LKS. Neurodevelopmental disorders result from impaired growth and development of the central nervous system, which includes the brain and spinal cord, and the nerves connecting them. WebGRIN2A encodes for a subunit of the NMDA receptor, and is affected by many different types of mutations, particularly de novo, although familial mutations have been described.

GRIN disorders (also GRIN-related disorders) are a group of neurodevelopmental disorders that result from mutations in genes coding for subunits of an N-methyl-D-aspartate (NMDA) receptor, which leads to dysfunction of glutamate signaling. Hereditary sensory neuropathies are a group of rare neurological disorders characterized by degeneration of the nervous system that frequently progresses to loss of feeling, especially in the hands and feet. Some affected individuals are compound heterozygotes, which means that they have inherited two different autosomal recessive mutations that have the combined effect of causing disease. NMDA receptor is composed of four subunits assembled from seven possible ones (GluN1, GluN2 A to D, and GluN3A and GluN3B). Too little signal might limit communication across the brain, which can limit the number of connections and might result in learning difficulties. This is true for people in different families with the same genetic variation and members within the same family with the same variation in theKIF1Agene. For information about clinical trials being conducted at the NIH Clinical Center in Bethesda, MD, contact the NIH Patient Recruitment Office: Toll-free: (800) 411-1222 Spastic paraplegia is classified as uncomplicated or pure when symptoms are confined to leg weakness and tightness.
