FDA approves drug from genetically-altered animals

The Food and Drug Administration has approved the first drug made with materials from genetically-engineered animals.
According to the New York Times, the drug is produced by livestock that have been given a human gene. GTC Biotherapeutics said regulators cleared its drug, ATryn, which is manufactured using milk from goats that have been scientifically-altered to produce extra antithrombin, a protein that acts as a natural blood thinner.
The FDA said it cleared the drug to treat patients with a rare hereditary disorder that causes a deficiency of the protein, putting them at higher risk of deadly blood clots. Genetically engineered, or GE, animals are not clones but rather animals that have had their DNA changed.
