Table 2. Shared Signature Microsatellite Loci.

Percentage of Shared Signature Variant Microsatellite Loci Between Cancer Comparisons
	GBM	LGG	MEL	MB
BC	9.3%	8.5%	9.4%	11%
GBM	-	12%	14%	0.2%
LGG	-	-	26%	33%
MEL	-	-	-	32%

Compared are four cancers with linkage to NTC/NCC lineage (GBM, LGG, MEL, and MB) compared with breast cancer (BC). Described is the relative percentage of signature genotypes that were identified from a shared cohort for any pair-wise comparison. The equation for this analysis is the following: % Common signature loci = ((x–z) / ((y₁ + y₂)–z)) *100; where x = signature loci shared in both cancers; y₁ = total signature loci in cancer1 (i.e. BC, GBM, LGG, or MEL); y₂ = total signature loci in cancer2 (i.e. GBM, LGG, MEL, or MB); z = CAML common to both cancers.
