High-specificity gene point mutation detection by PAM-free Cas12a system with double-stranded substrate positioning-unwinding.

A new gene-editing detection tool can spot cancer mutations more precisely without sequence limitations, improving early detection potential in liquid biopsies.

PAM-free Cas12a with double-stranded substrate positioning-unwinding enables high-specificity single-nucleotide variant detection without PAM sequence constraint, expanding the detectable mutation space for liquid biopsy and somatic cancer mutation monitoring. This record was retained from the prior triage attempt for PubMed pipeline handoff.
