Genetic testing could predict baby’s appearance, poll

PARENTS will soon be able to examine their unborn child’s future health, height and even eye colour before it is conceived, with a new genetic test likely to be available in Australia within the next five years, a leading fertility expert says.

The technology, reported in New Scientist this month, creates digital embryos by mixing the DNA of a woman with possible sperm donors, simulating how two people’s genes would interact during reproduction.

It allows a potential mother to eliminate donors who, when their genes are mixed with hers, could increase the risk of the baby inheriting genetic diseases, the report says.

‘‘We can already look at an embryo and tell if it will produce a child with a certain disease,’’ said Michael Chapman, fertility specialist and professor of obstetrics and gynaecology at the University of NSW.

‘‘That disease can then be avoided by using a different embryo that doesn’t have that genetic structure. This will take it a step further. It’s trying to get the best recipe when you bring an egg and sperm together.’’

The technology, to be launched by start-up company GenePeeks in the US in April, includes a list of non-medical traits, including what colour eyes the baby will have, their skin pigmentation, height and waist size.

‘‘The reasons we do it now are to avoid inherited disease, but it will go much further than that and we will be faced with some very difficult moral dilemmas about how far we take it,’’ Professor Chapman said.

‘‘The technology is way ahead of what society has even vaguely thought of.’’

New Scientist reports that before a woman selects a donor from a fertility clinic, the technology’s algorithms are run thousands of times for each donor. The potential mother pays almost $2000 for the test to screen for genetic mutations that can cause up to 500 diseases.

He said although digital embryo technology is not yet available in Australia, other tests which can identify birth defects or genetic problems, ‘‘have taken off in the past two years’’.
