  • Patent number: 11879157
    Abstract: The invention provides methods for assessment of risk for genetic conditions using target-enriched multiplexed parallel analysis, for example fetal risk for genetic conditions in prenatal testing. The methods of the invention utilize Target Capture Sequences (TACS) to thereby enrich for target sequences of interest, followed by massive parallel sequencing and statistical analysis of the enriched population. The methods of the disclosure can be used to determine carrier status of inheritable genetic abnormalities associated with genetic conditions and from this information the fetal risk of inheriting the genetic condition can be determined. Kits for carrying out the methods of the invention are also provided.

  • Publication number: 20230416826
    Abstract: The invention provides methods for assessment of fetal DNA samples using target-enriched multiplexed parallel analysis. The methods of the invention utilize Target Capture Sequences (TACS) to thereby enrich for target sequences of interest, followed by massive parallel sequencing and statistical analysis of the enriched population. The methods can be used with fetal or embryonic DNA samples, for example for the detection of the presence of genetic abnormalities, e.g., for purposes of IVF Pre-implantation Genetic Screening (PGS) and Diagnosis (PGD).

  • Publication number: 20220145368
    Abstract: The present invention relates to a method for the detection of genetic and or genomic abnormalities in a mixed sample, comprising the steps of biochemical and in-silico enrichment of a subset of cell-free DNA fragments derived from the mixed sample. The invention utilizes a pool of long DNA probes to enrich for sequences of interest in the mixed sample, followed by massive parallel sequencing and a computer-based analysis of the enriched sub-population to detect a risk of genetic and/or genomic abnormalities in the said sub-population of the mixed sample. The computer-based part of the method does not necessarily require alignment on a reference genome nor calibration values using reference samples. The method also comprises a kit for performing the invention.

  • Publication number: 20220106642
    Abstract: The invention provides methods for non-invasive prenatal testing that allow for detecting risk of chromosomal and subchromosomal abnormalities, including but not limited to aneuploidies, microdeletions and microduplications, insertions, translocations, inversions and small-size mutations including point mutations and mutational signatures. The methods of the invention utilize a pool of TArget Capture Sequences (TACS) to enrich for sequences of interest in a mixed sample containing both maternal and fetal DNA, followed by massive parallel sequencing and statistical analysis of the enriched population to thereby detect the risk of a genetic abnormality in the fetal DNA. Kits for carrying out the methods of the invention are also provided.

  • Publication number: 20200157602
    Abstract: The invention provides improved methods for enriching targeted genomic regions of interest to be analyzed by multiplexed parallel sequencing. The methods of the invention utilize a pool of TArget Capture Sequences (TACS), wherein the pool comprises a plurality of TACS families, each member of a family binding to the same target sequence but with different start and/or stop positions on the sequence (i.e., staggered binding of the family members to the target sequence) to thereby enrich for target sequences of interest, followed by massive parallel sequencing and statistical analysis of the enriched population. The methods of the invention can be used for a variety of clinical purposes, including non-invasive prenatal testing for chromosomal abnormalities, for example using a maternal blood sample or a sample of fetal cells, assessment of maternal and paternal carrier status for genetic disorders and detection of tumor biomarkers (e.g., liquid biopsy).
