Examining secretor status
The SNP rs601338 at chr19:48,703,417
in FUT2 determines whether an individual secrets the Lewis
antigen. An individual who is homozygous AA doesn't secret Lewis antigen ("non-secretors"), and
everything else does ("secretors"). We have provided a file
(GGVP/GGVP_secretor_status.txt
) that includes the real secretor status for these individuals.
Question. How accurate is the secretor status called from imputation, in comparison to the real data provided?
