21668-9
LaboratoryF5 gene p.Arg506Gln [Presence] in Blood or Tissue by Molecular genetics method
Definition
Factor V Leiden R506Q assays allow for the detection and genotyping of a single point mutation (G to A at position 1691, [NCBI dbSNP ID: rs6025]) of the human Factor V (F5) gene which leads to an amino acid change from arginine to glutamine (R506Q) in the F5 protein. Expected results include wild type, heterzygous, or homozygous for the R506Q (or 1691G>A) mutation.
