Sensitivity of Mutation Testing


These sensitivity classifications allow researchers to note the level of BRCA1 and BRCA2 testing that has been performed in the non-BRCA1/2 families. In most cases only one person has been tested from a family, so the sensitivities relate to that person's tests. Where more than one person has been tested, the sensitivities relate to the most sensitive tests performed.


Complete
very high sequencing plus MLPA
Very High
full sequencing of the coding region and splice junctions by Myriad, GTG, Peter Oefner, PMCC, Flinders SA (Full), POWH (Full)
High + MLPA
high sensitivity screening plus MLPA
High
DHPLC, chemical cleavage, sequencing by any lab other than Myriad or GTG for all exons.
High
restriction enzyme/sequencing
High
a combination of methods (e.g. PTT/DHPLC/SEQ/MLPA of all exons)
Moderate
PTT, DGGE for all exons
Moderate
PTT for exon 11 but sequencing/DHPLC for all remaining exons (includes PhaseI and PhaseII PeterMac Reports)
Low
e.g. SSCP, or analysis of only some of the exons by any method e.g.Jewish mutations only or predictive testing.
Low
MLPA only
