For example, genes selected for neuroblastoma (NB) are characteristic for nerve cells, such as neuronal N-cadherin, and meningioma 1; genes selected for rhabdomyosarcoma (RMS) are characteristic for muscle cells, such as alpha sarcoglycan, and slow skeletal troponin T1; genes selected for Burkitt lymphoma (BL) are characteristic for lymphocytes or blood cells, such as major histocompatibility complex (class II, DM alpha). This evidence concerns the gene TNNT1 and neuroblastoma.
