Abstract
Provided herein are methods for determining ploidy of an embryo. The methods can include the steps of amplifying, using a primer pair that amplifies a plurality of human genomic loci, nucleic acid from a preimplantation embryo to generate a plurality of amplicons, sequencing the amplicons to generate a plurality of sequence reads, matching the sequence reads to the genomic loci and counting a number of matches, and determining chromosome count based on the number of matches. Also provided herein are systems for determining chromosome count comprising a processor coupled to a tangible memory subsystem storing instructions. When executed by the processor, the instructions cause the system to implement the methods provided.
Claims26
A method for determining ploidy of an embryo, the method comprising:
- amplifying, using a primer pair that amplifies a plurality of human genomic loci, nucleic acid from a preimplantation embryo to generate a plurality of amplicons;
- sequencing the amplicons to generate a plurality of sequence reads;
- matching the sequence reads to the genomic loci and counting a number of matches;
- and
- determining chromosome count based on the number of matches.
A system for determining chromosome count, the system comprising:
- a processor coupled to a tangible memory subsystem storing instructions that when executed by the processor cause the system to:
- obtain sequence reads from amplicons, wherein the amplicons are generated by amplifying, using a primer pair that amplifies a plurality of human genomic loci, nucleic acid from a preimplantation embryo;
- match the sequence reads to the genomic loci;
- count a number of matches at the genomic loci;
- and
- determine chromosome count based on the number of matches.
