Hi all,
I am following the "**best practice**" suggested by broad institute to call variants from whole exome sequencing data. Currently, I am using **Mutect2** to call variants from **tumor** sample and **normal** sample based on latest reference genome **GRCh38.** 
But, I don't have *interval list* to use **-L** option.
Is there any way to generate interval list from exome sample which I have? or Is there any default interval list for exome data?
Thank You

something like:

    $ curl -s "http://hgdownload.cse.ucsc.edu/goldenPath/hg38/database/refGene.txt.gz" |\
        gunzip -c | cut -f 3,5,6 | sort -t $'\t' -k1,1 -k2,2n | bedtools merge -i - > exome.bed
