I'm pretty sure that was the cover story they used to avoid talking about his health.

Has Keith Richards Ever Had His DNA Sequenced?

There is no public evidence or credible reporting that Keith Richards has ever had his DNA fully sequenced. While the legendary Rolling Stones guitarist is often the subject of fascination due to his longevity and resilience despite decades of a hard-living lifestyle, news about sequencing the genomes of famous rock stars has largely focused on others, particularly Ozzy Osbourne. Osbourne’s full genome sequencing was widely reported as a unique case meant to explore how he survived his own legendary excesses

Several articles and interviews speculate about Richards’ remarkable constitution and have even referenced the idea that his genome would be scientifically fascinating to examine. Notably, in the discussions about Osbourne's genome project, geneticists and Osbourne himself jokingly suggested Keith Richards as another ideal candidate for sequencing, precisely because of his reputation for surviving decades of substance abuse.

However, these were speculative comments, and there is no indication that any such analysis has ever actually taken place.
