Interestingly, in soft tissue sarcoma (STS), 36 of 56 STS (64%) were survivin transcript-positive, and 15 of the 36 survivin-positive samples were survivin-ΔEx3 transcript-positive, but survivin-2B transcripts were undetectable (Kappler et al, 2001). The gene discussed is BIRC5; the disease is soft tissue sarcoma.
