What does the CHRM2 gene do?
The CHRM2 gene, located on the long arm of chromosome 7 (7q31-35), is involved in neuronal excitability, synaptic plasticity and feedback regulation of acetylcholine release, and has been implicated in higher cognitive processing.
What do muscarinic receptors do?
Introduction. Muscarinic receptors recognize the neurotransmitter acetylcholine, translating this recognition into electrical transients and altered cell behavior by activating and suppressing an assortment of signaling pathways.
Where are muscarinic receptors found?
Muscarinic receptors are abundantly expressed throughout the brain; however, they are also found in various other tissues in the body, such as the heart (17, 18), the bladder and pulmonary system (19), and the intestine (20).
What is GRIN1 mutation?
What are GRIN1-related disorders? Pathogenic variants (“mutations”) in the GRIN1 gene cause a spectrum of neurodevelopmental disorders that can include childhood-onset epilepsy, developmental delays, movement disorders, and features of autism spectrum disorder.
What is the CHRM3 gene?
CHRM3 (Cholinergic Receptor Muscarinic 3) is a Protein Coding gene. Diseases associated with CHRM3 include Prune Belly Syndrome and Cholinergic Urticaria. Among its related pathways are Metabolism and Peptide ligand-binding receptors.
What happens when muscarinic receptors are blocked?
Muscarinic antagonists, also known as anticholinergics, block muscarinic cholinergic receptors, producing mydriasis and bronchodilation, increasing heart rate, and inhibiting secretions.
What drug blocks muscarinic receptors?
Commonly used muscarinic antagonists include atropine, scopolamine, glycopyrrolate, and ipratropium bromide.
What are the symptoms of grin?

- limited or non-verbal communication.
What causes GRIN1?
GRIN1-related neurodevelopmental disorder (GRIN1-NDD) is inherited in one of two ways: In an autosomal dominant manner, typically caused by a de novo pathogenic missense variant. In an autosomal recessive manner.
