It’s a boy! Such a familiar statement but with somewhat peculiar and mysterious echo on the morning of 29th September, 2016. While drinking my first coffee of the day, I am wondering what is so unique about this boy to put him in the headlines of CNN, The Washington Post, The New York Times, The Guardian and every other -post or -times that exist around the world . Aha! ˝World’s first baby born with new ‘three parent’ technique. Ok, this requires a larger cup of coffee….
Even though many believe that all of our genes reside in the nuclei of our cells, it’s more complicated than that. A small part of human genome (only 37 genes compared to an estimated 20,000-25,000 genes in the whole genome) is situated outside the nucleus, in the “energy factories” of the cells called mitochondria. Mutations in one of these 37 genes might cause mitochondria failure, cell damage, and even cell death. Mitochondrial diseases are usually progressive; they manifest differently and affect those parts of the body that have highest energy demands: brain, muscles or heart. These tiny pieces of DNA are inherited only from our mothers. So, each of us inherited these 37 genes from our mother, who inherited them from hers, and so on and so forth through generations.
