VQSR filter

Hi,

I have exome sequencing data on 90 samples, and my lab uses the VQSR filter to remove low quality variants. I was wondering if I should also perform a genotype-level filter by DP/GQ post this VQSR filtering step. Is there a protocol that is recommended, or some metrics I can look at to determine if such a step is required?

Thanks,
Shweta
