A 21-year-old Chicago man who began college at age 9 and medical school three years later is about to become the youngest student ever awarded an M.D. by the University of Chicago.

Sho Yano, who was reading at age 2, writing at 3 and composing music at 5, will graduate this week from the Pritzker School of Medicine, where he also received a Ph.D. in molecular genetics and cell biology.

Yano earned his undergraduate degree from Loyola University at age 12, finishing in three years and graduating summa cum laude, the Chicago Tribune reported Sunday.

The average age of students entering medical school in the U.S is 23, and there were schools that refused Yano's admittance because of his age, worrying that medical school would hinder his ability to have a normal adolescence.

But the University of Chicago admitted Yano in 2003.

Yano told the paper he hopes his graduation will silence those who questioned his developmental aptitude when he entered medical school.

Genius, seemingly, runs in the Yano family.

His sister, Sayuri, is his only sibling, also and prodigy and his closest confidante. After receiving a bachelor's degree in biology from Roosevelt University in 2010, the 15-year-old is at Johns Hopkins University in Baltimore, pursuing a second bachelor's degree in violin performance.
