Uniparental disomy at chromosome 11p15.5 followed by HRAS mutations in embryonal rhabdomyosarcoma: lessons from Costello syndrome.
Costello syndrome (CS; MIM 218040) is characterized by short stature, facial dysmorphism, cardiac defects and predisposition to embryonal rhabdomyosarcoma (CS/ERMS) and other neoplasias.

The critical gene for ERMS development in this region is unknown. The...
متن کاملCytotoxicity of Zardaverine in Embryonal Rhabdomyosarcoma from a Costello Syndrome Patient
Costello syndrome (CS) patients suffer from a very high 10% incidence of embryonal rhabdomyosarcoma (ERMS). As tools to discover targeted therapeutic leads, we used a CS patient-derived ERMS cell line (CS242 ERMS) harboring a homozygous p.G12A mutation in HRAS, and a control cell line derived from the same patient comprising non-malignant CS242 fibroblasts with a heterozygous p.G12A HRAS mutati...
