the mutation is a polymorphism in the Chinese population and does not affect its mRNA transcription, but can slightly decrease the activity of human alpha-(1,2)-fucosyltransferase in vitro
F280S
-
missense polymorphism, almost inactive enzyme, responsible for some non-secretor cases
G247S
-
missense polymorphism, almost inactive enzyme, responsible for some non-secretor case
I129F
most frequent nonsense mutation of FUT2 in populations of Asian ancestry
L101F
-
spontaneous missense mutation frequent in Asian populations
S12F
-
the mutation does not significantly decrease the activity of alpha-(1,2)-fucosyltransferase and affect its kinetic property
W143X
Nonsense mutation of FUT2 with a allele frequency of 0.46 in populations of European ancestry. Individuals homozygous for the FUT2 nonsecretor genotype appear to be resistant to infection with Norovirus, suggesting that individuals homozygous for nonsecretor status may be unable to mediate host-microbe interactions.
