Steinberg, who has written extensively on PCSK9, said that patients with the protective mutation were shown to have an almost 90 percent reduced risk of coronary artery disease, compared with the general population.
"That's probably because their LDL has been low from birth," he said.
But he fails to mention OS.
There are certainly many genetic mutations that both reduce life expectancy and risk of coronary arterial disease.
PCKS9 might very well be real, but I would not trust this Steinberg guy for one second.
