FTDNA pads a haplotype with 1, 2, or 3 DYS464 alleles to the standard 4.
For example, most members of haplogroup N have a deletion that has left them
with only 2 DYS464 alleles; but FTDNA lists them as having 4.

FTDNA's DYS464X test, at additional cost, can determine the precise number
of DYS464 alleles. This test is routinely run on WTY candidates, apparently
as a preliminary test of the DNA sample.
