VT vtns variant information does not match VT epacts summary

[erampersaud]

We noticed that for any gene-based test result from EPACTS VT, that the number of individuals carrying variants (Burden_CNT) do not match with the .vnts files.

1. Is this a bug?

2. there a way to extract the individuals and their genotypes that contribute to the gene-based test results (taking phenotype and covariates into account)?

Example:
VT gene burden output
Number of individuals carrying variant in gene GRB14 = 8

Grepped for GRB14 across all *.epacts.vnts files = 5 ; 3 are missing.
