Alternative titles and symbols : Secretor factor; Se; SEC2;
Description : The classic human secretor locus (Se) FUT2 encodes alpha-(1,2)fucosyltransferase,
which regulates expression of the Lewis ABO(H) histo-blood group antigens on the surface
of epithelial cells and in body fluids and determines the secretion status of the
ABO antigens (see 110300). Secretor status of this polymorphic protein was used by
Mohr (1951) to provide the first autosomal linkage in humans between secretor factor
and the Lutheran blood group (see 111200) (summary by Hazra et al., 2008). The secretor
factor (Se) might be considered either a physiologic trait or an honorary blood group
(VAM). The individual who is a so-called secretor has demonstrable ABH blood group
antigen in the saliva and other body fluids; the nonsecretor does not. Secretor is
dominant.;
