False hype and hope about hypo-alergenic GM cats?

As Cory posted below, Allerca is taking deposits for $3,500 cats genetically engineered to be hypo-allergenic. Caveat emptor though. New Scientist reports that geneticists and allergists doubt Allerca’s claims.

It is probably possible to create cats that do not produce the most common protein allergen, says Thomas Platts-Mills, director of the Asthma and Allergic Disease Center at the University of Virginia in Charlottesville, US. But he adds that cats produce many more allergens, and that blocking production of the protein could damage the cat’s health.

Moreover, Allerca’s claims that a technique called RNA-induced gene silencing can work in cats are “unfounded”, says Greg Hannon at the Cold Spring Harbor Laboratory in New York state, and author of the book RNAi: A Guide to Gene Silencing. So far the technique has been used only in mice.
