Study suggests genetic testing on infants could be beneficial

There has been a long debate about whether newborns should undergo genetic testing.

The results of a new study suggest it may be a good idea.

Scientists conducted DNA sequencing on about 160 infants.

Almost 10 percent carried mutations that revealed a risk of diseases that could be treated in childhood, inclduing heart problems and hearing loss.

Surprisingly, the diseases were not in their family history.

Three of the babies had gene mutations that put them at a higher risk of adult-onset cancers.

The researchers say they are not recommending that it becomes part of the standard newborn screening at this time.

However, they do plan on following the babies and their parents long term.
