SSX1 and synovial sarcoma: Cytogenetics also plays a significant role in synovial sarcoma as both monophasic and biphasic types are characterized by reciprocal chromosomal translocations (x;18)(p11.2;q11.2) [28], translocating the SYT of chromosome 18 to either of the two homologous genes SSX1 or SSX2 on Xp11 [28].
