They did a DNA test on his hair and this is what AI says:
DNA analysis of a hair sample, featured in the documentary Dead Famous DNA, suggests Elvis Presley had genetic variants predisposing him to heart disease, specifically hypertrophic cardiomyopathy, which causes thickened heart muscle. These genetic factors likely contributed to his early death at 42, rather than just lifestyle, say researchers.
Key findings regarding Elvis’s genetic makeup include:
Heart Disease (Hypertrophic Cardiomyopathy): A "crucial" variant was identified, which aligns with his known, severe heart issues (enlarged heart, irregular heartbeat) and his mother’s early death from heart failure.
Other Genetic Tendencies: The analysis found, or Biographer Sally Hoedel highlighted, potential genetic links to high blood pressure, obesity, glaucoma, migraines, and an immune deficiency (hypogammaglobulinemia).
Genetic Inheritance: Many of these health issues appear to have been inherited from his mother, Gladys, and potentially exacerbated by consanguineous marriage (first cousins) among his maternal grandparents.
Physical Complications: Reports indicate he suffered from a serious Alpha-1-antitrypsin deficiency (linked to lung and liver issues).
These findings challenge the narrative that his death was solely due to drug abuse or unhealthy lifestyle, suggesting his body was under significant strain from inherited conditions.
