In finding the variant, researchers focused on a tumorsuppressor gene that is mutated. This gene is activated in most cancers and only occurs in people of African decent. About 2-8% of African and African Americans have this mutation. The researchers tested the variant on mice and 80% of those mice developed cancer. The types of cancer in which the mice developed were the common cancers found in African Americans.
This finding it truly life-saving! Now that scientists have isolated the mutated gene, accurate prognoses can be given. Different races may have different genetic explanations and these findings could start a revolution to finding the cure to cancer.
