Chrna7 - SNV Details

 Human Rare Diseases 
15q13.3 microdeletion syndrome

 Gene Information 
Gene Name Chrna7
Old Gene Names for Chrna7 Acra7
Gene Description cholinergic receptor, nicotinic, alpha polypeptide 7 [Source:MGI Symbol;Acc:MGI:99779]
MGI phenotype Nullizygous mice lack hippocampal fast nicotinic currents but show nicotine-induced seizures as well as altered anxiety behavior, fertility defects, airway basal cell hyperplasia. and higher TNF sythesis when endotoxemic. Newborns homozygous for a knock-in allele die with increased neuron apoptosis.
