Definition | The protein variant model is an AMR detection model. Protein variant models are similar to protein homolog models - they detect the presence of a protein sequence based on its similarity to a curated reference sequence, but secondarily search submitted query sequences for curated sets of mutations shown clinically to confer resistance relative to wild-type. This model includes a protein reference sequence, a curated BLASTP cut-off, and mapped resistance variants. Mapped resistance variants may include any or all of: single resistance variants, insertions, deletions, co-dependent resistance variants, nonsense SNPs, and/or frameshift mutations. Protein variant model matches to reference sequences are categorized on two criteria: strict and loose. A strict match has a BLASTP bitscore above the curated BLASTP cutoff value and contains at least one detected mutation from amongst the mapped resistance variants; a loose match has a BLASTP bitscore below the curated BLASTP cutoff value but still contains at least one detected mutation from amongst the mapped resistance variants. Regardless of BLASTP bitscore, if a sequence does not contain one of the mapped resistance variants, it is not considered a match and not detected by the protein variant model. | ||
