A specific chromosomal translocation t(9;22)(q22;q12) leading to a fusion gene, EWS-CHN has been found in 75 % EMC cases [6], and another fusion gene TAF2N-CHN caused by t(9;17)(q22;q11.2) translocation has recently been identified [5]. This evidence concerns the gene TAF15 and extraskeletal myxoid chondrosarcoma.
