aIn bold SNP-specific base, underlined base deliberately changed to create mismatch with template
bLat control primers: Lat1-F AGACCACGAGAACGATATTTGC, Lat2-R TTCTTGCCTTTTCATATCCAGACA
cSecond set of primers with deliberate mismatch closer to 3’-SNP end of primer gives better results at some laboratories
