At-home DNA test screens for breast cancer

Posted: Updated:

Genetic testing company 23 and Me has been given federal approval to sell at-home test kits to detect three breast cancer gene mutations.

The FDA says this will be the first direct-to-consumer DNA test for these particular breast cancer gene mutations.

A 23 and Me spokeswoman said the test for the three BRCA-1 and BRCA-2

Breast cancer gene mutations will be added in the coming weeks to the broader "health plus ancestry" services.

There will be no increase to the existing $199 testing cost.

The FDA says the test can only detect three out of more than one-thousand known b-r-c-a mutations. 

The FDA says those three hereditary mutations occur in about two percent of Ashkenazi Jewish women, but rarely in anyone else.
