Two thoughts on this:
1. Your FDR (Not Franklin Delano Roosevelt) sounds like another name
for Type I error rate. The definition of "reasonably reliable FDRs"
would seem to relate to the status of the literature on this issue among
researchers in genotyping. As more reports of FRDs in genotyping are
published, I would expect that methodology for estimation and the
standard for accuracy would similarly evolve.
2. Have you tried the Bioconductor (www.bioconductor.org/)
listserve? They might be able to say something more useful than a
general list like this.
