WebThe median life expectancy is about 55 years. WebAbout GRIN2B related syndrome. Epub 2016 Oct 19. Heres how it works. Some studies suggest that this protein is essential for the function and survival of sensory nerve cells (neurons). Symptoms: This section is currently in development. While some affected individuals may have symptoms and inheritance patterns that fit neatly into these categories, others do not. Apr;133(4):280. At least two distinct disorders are associated with variations in theKIF1Agene that are inherited in an autosomal recessive pattern. Following an initial diagnosis, a developmental assessment may be performed and appropriate occupational, physical, speech and feeding therapies be instituted. Suite 310 Some people with a KIF1A-related disorder have a variation in theKIF1Agene have a new (sporadic orde novo) mutation, which means that in nearly all families the gene mutation has occurred at the time of the formation of the egg or sperm for that child only, and no other family member will be affected. NORD and MedicAlert Foundation have teamed up on a new program to provide protection to rare disease patients in emergency situations. Danbury, CT 06810 WebGRIN1-Related Neurodevelopmental Disorder (GRIN1-NDD) What is GRIN1-Related Neurodevelopmental Disorder (GRIN1-NDD)? Many rare diseases have limited information. Through it all, Chris Hughes nodded approvingly, an unnerving grin on his face. About one-quarter of affected individuals have features of autism spectrum disorder, which is characterized by impaired communication and social interaction. Different research projects are ongoing to further elucidate the nature and impact of genetic variation in GRIN2A.

Genes provide instructions for creating proteins that play a critical role in many functions of the body. Individuals with recessive forms of KIF1A-related disorder may have symptoms that fit neatly into the categories described or may have symptoms that look more like the autosomal dominant form of the condition described above.

GRIN2B-related neurodevelopmental disorder is characterized in all affected individuals by mild to profound developmental delay / intellectual disability (DD/ID). Researchers are unsure how abnormal activity of NMDA receptors prevents normal growth and development of the brain or why too much or too little activity lead to similar neurological problems in people with GRIN2B-related neurodevelopmental disorder.
