Greetings

I am working on a small bioinformatics project. Using the common disease, common variant hypothesis I am assuming that the common disease I am looking at is caused by common variants. Is there a formula which describes how many individuals need to be sequenced to find a specific percentage of the common variants in that species? So for example, if I have the sequence of 100 individuals I would like to estimate how much of the common variation (where common is defined as occuring in 1% of the population) might be present in the data (and hence how much of the common variation might not be present). I don't know if such a formula exists of whether it is too difficult to predict because of the variables (e.g sequencing depth, exome vs whole genome). I looked at the 1000 genome project which estimates to have discovered 95% of common variation. The different sequencing approaches in this project had a different power to detect variants.

Thank-you for your time
