*Number of microsatellite markers analyzed in parentheses. Tetra, Tetranucleotide repeat; Tri, trinucleotide repeat; Di, dinucleotide repeat; Mono, mononucleotide.
†BAT-26, BAT-25, and TGF-beta RII mononucleotide repeats analyzed.
‡The rate of MSI is the proportion of instable loci observed compared to the total number of loci examined (n = 32).
