Genome-wide DNA methylation analysis revealed epigenetic mechanism underlying end-stage renal disease.

Key takeaways

Scientists looked at chemical tags on DNA, called methylation, which switch genes on and off without changing the genes themselves. They compared 1,031 people with kidney failure against 704 people without it, across two separate groups of people. They found 52 spots on the DNA where the tags reliably differed. The same spots showed up no matter which kidney disease a person started with, which hints at a shared path to failure, but this study shows a link and not proof of cause.
