Can CVNkit call CNV correctly at HLA genes region?

Hello, I use CNVkit to call CNV from WES data. I check my WES target region and find this include HLA genes region.

I want to know can CNVKIT call CNV good quality at those regions? I guess this depends on BWA alignment and Hybrid capture at HLA regions, so my answer is no. What do you think?

Thanks @linouhao. I don't need to handle those regions. All I want to discuss is what will affect CNVKIT performance at those regions.
