Abstract
Methods and compositions for detecting genetic instability using digital amplification assays. The methods may be performed in a set of isolated volumes and generally may involve competitive hybridization of a competitor and a probe/primer with a normal allele and one or more mutant alleles of a microsatellite locus. The competitor may be configured to compete similarly with, or to outcompete, the primer/probe for hybridization with the normal allele. The primer/probe may be configured to outcompete the competitor for hybridization with various mutant alleles of the locus that alter the length of the repetitive sequence by different amounts. Isolated volumes in which the primer/probe outcompetes the competitor may be enumerated, and represent one or more of the mutant alleles. The methods may enable diagnosing microsatellite instability and treating a subject based on the diagnosis.
