Identification of the E1fE1k cholinesterase genotype.


A family segregating for the A, F, and K alleles at cholinesterase locus 1 is described. This work, undertaken after the proband suffered prolonged apnoea after the use of suxamethonium during the delivery of her third child, resulted in the identification of the E1fE1k genotype in her oldest son.
