There are multiple definitions:

1. single-locus variant(English)

   • bacterial sequence type that differs at only one of the seven canonical multilocus sequence typing loci. Estimating the relative roles of recombination and point mutation in the generation of new alleles that lead to SLVs is helpful in understanding how organisms evolve

2. standard liver volume(English)

   • is important in risk assessment for major hepatectomy. Calculating SLV is more complicated in children than in adults due to changes in BW and BH owing to overall growth
   • aFLR, BH, BW, FLR, FLV, RLV, sFLR, TFLV, TLV
