Final answer:
The overexpression of the c-myc gene results in the creation of an oncogene and causes malignancy, exemplified by Burkitt's Lymphoma.
Step-by-step explanation:
Abnormal overexpression of c-myc results in the formation of an oncogene, leading to malignancy. The c-myc gene is a proto-oncogene that normally promotes cell growth and reproduction, but when overexpressed or mutated, it becomes an oncogene. This process is exemplified in conditions such as Burkitt's Lymphoma, where the overexpressed myc leads to the transformation of normal B cells into cancerous ones, causing tumors and uncontrolled cell growth. The overexpression of c-myc could be regarded as a result of a fusion gene since it is a translocation mutation involving the c-myc gene that characterizes Burkitt's Lymphoma.
