-clogit- with the "cluster" option?

I'd like to do something like McNemar's test, -mcc-, where I'm comparing
presence of two dichotomous traits in each person. [In this case, is a
finding more common on the left side of the spine, compared to the right.]

The problem is that the subjects are twins, in this analysis a nuisance
parameter, but svyset or cluster(pair) are not options for mcc.

For continuous outcomes I can get the equivalent of a paired t-test by
computing the difference and then getting the p-values from the
intercept in

reg difference, cluster(pair)

but I've not come up with anything along these lines either.

Any guidance would be appreciated, thanks!
