Mom had bloodclot homocysteine was elevated I got checked mine 10.9 normal 10.4 so can this cause me to die?

No. Hello Jill, Homocysteine is a marker of inflammation. An elevated level just means you have to pay attention to your health by eating lots of fresh fruits and vegetables, exercise moderately and control your stress. Genetics plays only a partial role in the development of disease. Lifestyle matters more.
