Overview
Causes
Chondromyxoid Fibroma
There are no established causes for chondromyxoid fibroma. However, scientists have noted an association of chondromyxoid fibroma with certain chromosomal abnormalities. Chondromyxoid fibroma may be caused by a clonal rearrangement of chromosome 6. The oncogene activation resulting from this clonal rearrangement is likely to be involved in the pathogenesis of chondromyxoid fibroma. Scientists have found that the glutamate receptor gene GRM1 recombines with several partner genes through promoter swapping and gene fusion. The subjects with chondromyxoid fibroma also showed increases in GRM1 gene expression levels.[1][2][3]
