Clinics and Pathology

Disease Giant cell tumour of bone is a locally destructive tumor, usually seen in patients over 20 years of age, a borderline lesion between benign and malignant tumours, with a good prognosis, despite of recurrences and, more rarely, pulmonary metastases. The most frequent genetic finding is telomeric associations.


Note In a study by Scotlandi et al., 2000, was found that a minor population of cells from giant cell tumour of bone samples had an EWSR1/FLI1 transcript, but this was found in a high percentage of samples (13/15).

Genes involved and Proteins

Gene NameFLI1 (Friend leukemia virus integration 1)
Location 11q24.3
Protein From N-term to C-term: a 5' ETS domain, a Fli-1-specific transcriptional activation domain, and a 3' ETS transcriptional activation domain. Member of ETS transcription factor gene family. FLI1 binds to DNA in a sequence-specific manner.

Gene NameEWSR1 (Ewing sarcoma breakpoint region 1)
Location 22q12.2
Protein From N-term to C-term: a transactivation domain (TAD) containing multiple degenerate hexapeptide repeats, 3 arginine/glycine rich domains (RGG regions), a RNA recognition motif, and a RanBP2 type Zinc finger. Role in transcriptional regulation for specific genes and in mRNA splicing.

Result of the chromosomal anomaly

Hybrid Gene
Description 5' EWSR1 - 3' FLI1. EWSR1 exon 7 is fused in frame to FLI1 exon 6 and/or 5 (type 1 and type 2 fusions respectively), indicating, when both transcripts were produced in a given sample, genetic heterogeneity within the tumour.
Fusion Protein
Description Fusion of the N terminal transactivation domain of EWSR1 to the ETS type DNA binding domain of FLI1.
