Gene responsible for making people look older identified
Q. Scientists have found that a specific gene variant can make people look two years younger than their actual age. What is it called?- Published on 02 May 16a. MC1R
b. MC2R
c. MC3R
d. None of the above
ANSWER: MC1R
Scientists already know that the gene in question, known as MC1R, is responsible for producing red hair and pale skin, according to the report in the journal Current Biology.
- But now they have identified a variation in this gene that seems to age people faster.
- For the current study, scientists examined the genomes of more than 2,600 elderly Dutch Europeans "for DNA variants associated with differences in perceived facial age and wrinkling as estimated from digital facial images," the report said.
- They found the influence of the MC1R gene variant was not swayed by age, sex, skin color, or sun damage.
MC1R is also known for its role in inflammation and DNA damage repair, processes that may influence how youthful a person appears, researchers said.
