New regions of the human genome linked to skin color variation in some African populations
Findings may shed light on how genes repair DNA damage caused by UV radiation.
In the first study of its kind, an international team of genomics researchers has identified new regions of the human genome that are associated with skin color variation in some African populations, opening new avenues for research on skin diseases and cancer in all populations. These findings may help researchers determine if humans with certain DNA sequences are more or less susceptible to DNA damage caused by ultraviolet radiation (UVR) or respond to cellular stress differently. National Institutes of Health researchers contributed to this effort, led by Sarah Tishkoff, Ph.D., at the University of Pennsylvania in Philadelphia. The findings were published October 12, 2017, in the journal Science.
