When a study has tested 500 cases and 500 controls, and has not found
any carrier of a mutation.
How do I based on these numbers calculated a maximum frequency of the
mutation in the population studied? With 95% Confidence interval? Is it
possible in STATA?

One of the smart things in Stata is the immediate commands:
. cii 1000 0 , binomial
-- Binomial
Exact --
Variable | Obs Mean Std. Err. [95% Conf.
Interval]

Hope this helps
