Your best option is to genotype the samples that you have for the
marker in question and estimate the frequency from that.
Alternatively you may find estimates of the allele frequency in
various online databases (although you haven't disclosed the organism
in question, or whether they are haploid or diploid, but given the
context I'd say a fair bet is to guess that you are dealing with human
diploid data (unless your marker lies on the X or Y chromosome).
As Austin has elegantly demonstrated theres not much you can do with
the information you have provided.
