The dibucaine number, which is a measure of the enzymatic activity of pseudocholinesterase, was 81 (Normal values are > 70).
The serum pseudocholinesterase level and serum dibucaine inhibition tests were performed at the Mayo Clinic Laboratory.
It is possible that the patient had a pseudocholinesterase enzyme variant, such as the fluoride -resistant or K type, which is unlikely to be detected utilizing a standard dibucaine inhibition test.

Biochemical phenotypes are defined by the pattern of values obtained after differential enzyme inhibition to determine "inhibitor numbers," e.g., the dibucaine number (DN).
The five BCHE mutations analyzed in the mutation screen were dibucaine (D70G; [Asp.sup.70] [right arrow] Gly), silent-1 (sil-1; G117FS; Gly GGT to GGAG), fluoride-1 (flu-1; T243M; [Thr.sup.243] [right arrow] Met), fluoride-2 (flu-2; G390V; [Gly.sup.390] [right arrow] Val), and K-variant (A539T; [Ala.sup.539] [right arrow] Thr; Fig.
An exon 2 region that included the dibucaine (D70G) and sil-1 (G117FS) loci was amplified as a single 570-bp fragment with primers BC14 and BC3 (Table 2).

DN is the percent inhibition of activity caused by 0.03 [micro]mol/L dibucaine and FN is the percent inhibition of activity caused by 4 [micro]mol/L sodium fluoride [15].
