If I take for instance, my blood and give it to two or three different companies to sequence my entire genome, will results of multiple companies match to the letter?
Similarly if I repeat sequencing will the one I take today and the one in month after, be the same?<p>If not, how much is the discrepancy?
If you get your genome processed into a VCF file, each variant will be listed together with sort of a posterior probability. The discrepancy will be proportional to how stringent your filter is, as variant calling methods are well calibrated. There's a lot of literature on this.
