Type Gene Modification Chromosome rearrangement Protein expression Protein Function constitutional germinal mutation       in apnea following the administration of the surgical muscle-relaxant succinylcholine tumoral fusion       dysregulated in myelogenous disorders

Susceptibility

to cocaine poisoning

Variant & Polymorphism other	contradictory evidence for association of the K variant with late onset Alzheimer disease
	mutations that reduce serum BCHE activity increasing the risk for cocaine poisoning
	homozygosity, but not heterozygosity, for BCHE-K is a potential risk factor for the development of neurofibrillary tangles pathology in young individuals implicating BCHE-K in the pathogenesis of early AD (Ghebremedhin 2007)
