Summary of genetic analysis
| Case | Homogeneous LOH | Heterogeneous LOH | Genetic pattern | FAL |
|---|---|---|---|---|
| Microsatellite markers listed showed LOH for each case. | ||||
| α, β, allelic losses of the opposite chromosomal arms; complex, single clonal process cannot be confirmed because of the complexity of the LOH pattern; divergence, single clonal process with subsequent genetic divergence; homogeneous, all the foci show the same genetic alteration; progression, linear genetic progression of a clone. | ||||
| FAL, fractional allelic loss; LOH, loss of heterozygosity. | ||||
