Mitochondrial Donation Treatment (MDT)


Source: HT


Context:  A baby has been born in the UK using a technique called mitochondrial donation treatment (MDT) (popularly called ‘Three Parents Baby’), which involves using the DNA of three people in an effort to prevent children from inheriting incurable diseases.



The procedure combines the sperm and eggs from the biological parents with mitochondria from a donor’s eggs. Harmful mutations in mitochondria, which are inherited only from the mother, can affect all the children a woman has. As of now, the technique is still in its experimental stage.

Approximately 1 in 5,000-10,000 children are born each year with mitochondrial disease. Concerns: Development of designer babies, dilutes parenthood, costly in nature etc.
