The world’s first baby has been born in the United States using a new scientific Technic which combined DNA of three persons: father, mother and egg donor.
The somewhat controversial scientific procedure was conducted to prevent the baby from inheriting a fatal genetic disease from the mother. According to experts, the move heralds a new era in medicine and could help other families with rare genetic conditions.
A report in the magazine, New Scientist, said the baby was born on April 6, 2016, and doctors confirmed he’s healthy. The infant’s parents were treated by the U.S. fertility specialists in Mexico, where there are no laws prohibiting such methods.
We learned that the baby’s mother carries a genetic mutation for Leigh syndrome, a rare neurological disorder that usually becomes apparent in the first year of life and is generally fatal.
With the latest discovery of DNA editing, scientists were able to use this technique to removing some of the mother’s DNA from the egg, and leaving the disease-causing DNA behind.
The healthy DNA was slipped into a donor’s egg, which was then fertilized. As a result, the baby inherited DNA from both parents and the egg donor.
About the rare Leigh Syndrome
This Mitochondria DNA infected disease can affect both parents and children. The Jordanian family involved in the 3-parent DNA merge had already experienced four miscarriages as well as the death of two children – one at eight months and the other at six years of age.
Symptoms of Leigh disease usually progress rapidly and lead to generalized weakness, a lack of muscle tone and a buildup of lactic acid in the body, which can cause respiratory and kidney problems. Children rarely live more than six or seven years.
Research showed that the severe neurological disorder only affects at least one in 40,000 new-born babies, which become apparent during the first year of a child’s life.
First signs include vomiting, diarrhoea, and difficulty with swallowing; causes the progressive loss of movement, and deterioration of mental functions.
