From: Mapping loss of heterozygosity in normal human breast cells from BRCA1/2 carriers
Loss of heterozygosity in normal cell clones demonstrated by amplification of microsatellites D17s1323 (A) and D13s267 (B). The normal tissue control for each sample shows two allele peaks. The ‘normal’ clones from samples 3 and 4 each demonstrate loss of one allele (arrow).
