A British Tv show has unravelled Elvis Presley's genetic code in an effort to gain extra insight into the singer's death. Bosses of Channel 4's Dead Famous Dna tracked down samples of the singer's hair and used it to sequence his genome, which revealed he had several genetic mutations which may explain a number of the Blue Suede Shoes singer's health woes, including an enlarged heart and struggles with glaucoma and poor eyesight.
