Abstract
Nucleic acid amplification assays for mutations to two short sections of the fungal gene FKS1. Mutations in these target sequences have been shown to correlate with resistance to echinocandin-class drugs. Assays may include detection by sequencing or by labeled hybridization probes. Also, primers, probes and reagent kits for performing such assays.
Claims20
A nucleic acid assay for echinocandin drug resistance in fungi susceptible to echinocandin drugs and containing the FKS1 gene corresponding to 1-3β-D-glucan synthase subunit Fks1p comprising amplifying a first nucleic acid target sequence of the FKS1 corresponding to at least a portion of CaFks1p amino acids 636 to 654 that includes amino acids 641 to 649, and detecting any difference from the wild-type allele in said amplified first target sequence.
An oligonucleotide set that includes a first pair of forward and reverse primers for amplifying said first target sequence and forward and reverse primers for amplifying a first target sequence of the FKS1 gene corresponding to 1-3-β-D glucan synthase subunit Fks1p corresponding to at least a portion of CaFks1p amino acids 636-654 that includes amino acids 641-649.
