Four typical types of STR alterations in HCC. (A) partial loss of heterozygosity (pLOH), (e.g., allele 18/20 → allele 18/20, but the peak of ‘20’ allele in cancer tissues was significantly reduced); (B) complete loss of heterozygosity (cLOH) (e.g., allele 8/9→ allele 9/9); (C) an additional allele (Aadd) (e.g., allele 22/23 → allele 21/22/23); (D) the occurrence of a new allele (Anew) (e.g., allele 17/20 → allele 18/20).
