Abstract
Systems, methods, and devices for generating synthetic genomic datasets and validating bioinformatic pipelines for genomic analysis are disclosed. In preferred embodiments, synthetic maternal and paternal datasets with known variants are used with matched normal synthetic datasets to validate various bioinformatic pipelines. Bioinformatic pipelines are evaluated using the synthetic datasets to assess design changes and improvements. Accuracy, PPV, specificity, sensitivity, reproducibility, and limit of detection of the pipelines in calling variants in synthetic datasets is reported.
Claims20
A computer-implemented method of generating a synthetic digital genomic dataset, comprising:
- obtaining a reference genome and introducing a plurality of SNPs at a predetermined frequency and distribution into at least one autosome and an X-chromosome of the reference genome to so prepare a synthetic maternal genome;
- introducing a plurality of SNPs at a predetermined frequency and distribution into at least one autosome and an X- or Y-chromosome of the reference genome to so prepare a synthetic paternal genome;
- and
- merging the maternal and paternal synthetic genomes into a combined synthetic digital genomic dataset.
