Clinics and Pathology

Disease Aneurysmal bone cysts
Note Benign but locally aggressive tumor.
Phenotype / cell stem origin Occurs mainly in vertebrae and flat bones. Multiple involvement is frequent.
Etiology May involve the arrest of maturation of the osteoblasts caused by USP6 overexpression and dysregulation of autocrine BMP (bone morphology protein) signaling (Lau et al., 2010).
Epidemiology Usually seen in patients aged 10-20 years; represents about 5% of primary bone tumours; slightly more frequent in female patients.
Clinics Forms a spongy hemorrhagic mass; symptoms are pain, swelling, pathological fractures. Two cases to date was found with a t(17;17)(p13;q21), a 8-year-old boy with a tumor of the soft tissues, and a 13-year-old boy with a tumor located in the tibia (Oliveira et al., 2005; Panagopoulos et al., 2008).
Treatment Surgical curetage.
Prognosis Recurrence occurs in one fourth of cases.

The t(17;17)(p13;q21) was the sole anomaly.

Genes involved and Proteins

Gene NameCOL1A1 (collagen, type I, alpha 1)
Location 17q21.33
Protein Two pro a1(I) chain associate in trimers with one pro a2(I) chain to form the type I collagen fibrils after proteolysis. Constituent of the extra cellular matrix in connective tissue of bone, skin, tendon, ligament, teeth.
Germinal mutation COL1A1 has been found mutated in osteoporosis, osteogenesis imperfecta types I-IV, Ehlers-Danlos types I and VIIA, and Caffey disease (Stover and Verrelli, 2011).

Gene NameUSP6 (ubiquitin specific protease 6 (Tre-2 oncogene))
Location 17p13.2
Protein USP6, also called TRE17/ubiquitin-specific protease 6 (USP6), is a deubiquitinase. It is the first de-ubiquitinating enzyme to activate NF-KB, and requires both catalytic subunits of IKK (IKKalpha and IKKbeta) (Pringle et al., 2011).

Result of the chromosomal anomaly

Hybrid Gene
Description 5' COL1A1 - 3' USP6
Fusion Protein
Description Fusion of the exon 1 of COL1A1 to a splicing variant of USP exon 1 in the case reported in Oliveira et al., 2005.
