Agilent Sureselect : Missed Regions picking up if we give gene coordinates seperately

Question

[Amk]

Dear all,

I am using Agilent SureSelect to design probes for a particular gene. I got the missed regions in a bed file after finalizing design.I input these missed regions into the designs because I don't want to miss, as it is a promoter region of that gene. I came to see that SureSelect covers that region with a coverage of 75% which it said to have missed in the design with the entire coordinate of the gene. Can I go with that design(with missed region added)? Is 75% is a good coverage?

All answers are appreciated.

Thank you

Amk
