    Oregon scientists make embryos with 2 women, 1 man

    NEW YORK (AP) — Scientists in Oregon have created embryos with genes from one man and two women, using a provocative technique that could someday be used to prevent babies from inheriting certain rare incurable diseases.

    The researchers at Oregon Health & Sciences University said they are not using the embryos to produce children, and it is not clear when or even if this technique will be put to use. .............

    The genes they want to replace aren't the kind most people think of, which are found in the nucleus of cells and influence traits such as eye color and height. Rather, these genes reside outside the nucleus in energy-producing structures called mitochondria. These genes are passed along only by mothers, not fathers.

    About 1 in every 5,000 children inherits a disease caused by defective mitochondrial genes. The defects can cause many rare diseases with a host of symptoms, including strokes, epilepsy, dementia, blindness, deafness, kidney failure and heart disease.

    The new technique, if approved someday for routine use, would allow a woman to give birth to a baby who inherits her nucleus DNA but not her mitochondrial DNA. Here's how it would work:.................more at link......

    But I agree, this makes me uneasy.

    Maybe those with such extreme genetic defects could adopt?
