1. A method for amplifying and sequencing DNA, comprising:
- ligating adaptors to cell-free DNA isolated from a biological sample, wherein the adaptors each comprises a universal priming sequence and a molecular barcode;
performing a first PCR to simultaneously amplify at least 10 target loci using a first universal primer and at least 10 target-specific primers in a single reaction volume;
performing a second, nested PCR to simultaneously amplify the at least 10 target loci using a second universal primer and at least 10 inner target-specific primers in a single reaction volume, wherein at least one of the primers comprises a sequencing tag; and
performing high-throughput sequencing to sequence the amplified DNA comprising the target loci.

Abstract
The invention provides methods for simultaneously amplifying multiple nucleic acid regions of interest in one reaction volume as well as methods for selecting a library of primers for use in such amplification methods. The invention also provides library of primers with desirable characteristics, such as minimal formation of amplified primer dimers or other non-target amplicons.
