A person’s skin pigment is influenced by the melanocortin-1 (MC1R) gene receptor. For the population’s 1 to 2 percent of redheads, a mutation in MC1R accounts for their red hair color and typical light skin. Now researchers from Harvard Medical School have discovered that the same MC1R mutation responsible for the red-hair phenotype also promotes an important cancer-causing pathway. Read more here.
