A recently filed patent (Publication Number: US20230407375A1) outlines a method for detecting the presence, absence, or amount of multiple genetic variants in a composition. The method involves preparing amplicons from target nucleic acid species, hybridizing these amplicons to oligonucleotide species, and contacting them with an extension composition containing terminating nucleotides. Importantly, the terminating nucleotides include a capture agent, and the extension process distinguishes between different genetic variants. The extended oligonucleotide species are then captured on a solid phase, released, and detected by mass spectrometry to determine the genetic variants' presence, absence, or quantity.

This innovative method offers a comprehensive approach to detecting genetic variants by utilizing a combination of hybridization, extension, and mass spectrometry techniques. By incorporating a capture agent into the terminating nucleotides and distinguishing between different variants based on their extension patterns, the method provides a reliable and efficient way to analyze genetic compositions. The use of mass spectrometry for detection adds a high level of sensitivity and accuracy to the process, ensuring precise results in determining the genetic variants' status. Overall, this patent presents a sophisticated and effective method for genetic variant detection that could have significant implications in various fields such as medical diagnostics, research, and personalized medicine.
