Additional Information

​Rhabdomyosarcomas (RMS) are classified mainly into alveolar, embryonal , spindle cell and pleomorphic types. Recent publications report a recurrent somatic point mutation c.365T>G encoding p.Leu122Arg in the myogenic transcription factor MYOD1 in approximately 10% of spindle cell RMS, resulting in the mutated MyoD1 protein having MYC-like properties. MYOD1-mutated spindle cell RMS have an aggressive clinical course.

Expected Test Result: MyoD1 p.L122R mutation detected/not detected.

The molecular test result must always be correlated with clinical and histopathological findings by an appropriately trained, qualified and experienced pathologist.
